Blow Molding Troubleshooting Guide Top 5 Problems

Blow Molding Troubleshooting Guide – Top 5 Problems

Blow Molding Troubleshooting Guide – Top 5 Problems – Extrusion Blow Molding is a popular process for the production of HDPE chemical drums, edible oil jerry cans, beverage, chemical or pharmaceutical bottles, and more. Such popularity comes from being the most economical and highest production output forming process of plastic products that are not only durable, but very high quality. However, there is a chance of encountering some problems during this process, so when it comes to blow molding defects, it is extremely important that you learn to identify their origin and know how to handle each of them.

This blow molding troubleshooting guide will therefore introduce you to the Top 6 Common Defects and Problems of HDPE Extrusion Blow Molding, their possible causes, and solutions and recommendations which can help you obtain the best plastic products possible.

Top 5 Problems and Solutions

Becoming familiarized with blow molding defects should always be a priority. This way, when production problems arise, coming up with an efficient solution will not take too long and overall plant productivity will be kept. Therefore, this leaves no doubt that having a proactive approach to blow molding troubleshooting is necessary to prevent delays and maintain a company’s overall performance.

Blow molding troubleshooting includes a variety of defects including the following:

1.  Leakage

Leakage from HDPE bottles can be caused by many reasons, it can be due to tear in the bottle’s wall, poor welding of the molten plastic in areas such as the bottom, side or top handles; it can also be caused by the melted resin being contaminated by dirt or impurities coming from recycled material, which can lead to the product’s walls not being leakproof.

For plastic products with a narrow neck (such as bottles, jerry cans and narrow mouth drums) the source of the leakage can be at the top surface of the neck and might be a little harder to detect. When designing the tooling for your product, the blow molding manufacturer must make sure the blow pin nozzle and the mold are the perfect match, depending on the parison wall thickness, the gap between these two should be narrow enough to let the blow pin push the material inside the mold so the plastic can fill the space between the mold and the blow pin, hence making the top of the neck flat (avoiding leakage when sealing the container). If this gap is too big, the material will not be pushed inwards to fill the space and the top surface of the neck will not be flat, thus, causing leakage.

2. Rocker Bottoms

Why are rocker bottoms caused in bottles? Unstable or rocker bottoms of blow molded bottles is a problem usually caused by insufficient cooling of the blown bottle before removing it from its mold. If this is the case, try increasing the water flow of your cooling system. If there is still no result, you can also check the blow molding machine’s cooling channels for any blockage and clean them. Sometimes, the problem can be caused by excessive thickness of the parison in the flasher area at the bottom, this causes the mold to not fully close at this point and the material not touching the mold completely as it is supposed to; thus, make sure the parison thickness at this area is adequate to allow the mold to fully close.

Additionally, rocker bottoms can also be originated by poor air exhaust from the product’s neck after the blowing cycle has finished and before the mold opens; as when the product is being formed, there is air being blown at a constant pressure pushing the Parison walls against the mold, so when this process finishes, the blow pin nozzle should slightly retract and allow the extra pressure out, otherwise this pressure will most likely expand the product at the bottom, hence resulting in an unstable bottle.

3. Tearing of Welding Line at Pinch-off (or Deflashing)

Tearing of a container when deflashing the flasher material can happen and especially at the welding lines of the product (such as handle areas and the product’s bottom), a very common cause of this issue is the mold close slow speed. What does this mean exactly? To catch the parison inside, the clamping unit must close the blow mold in two steps: 1st mold close (fast speed) and 2nd mold close (slow speed), the purpose of the 2nd mold close with slow speed is to push the material inwards the mold in order to form strong welding lines, and thus, avoid tearing at these areas when removing the scrap material. So, if your bottle, drum or jerry can is having this problem, try reducing the speed of the mold slow close.

Blow Molding Troubleshooting Guide Top 5 Problems

If after reducing the mold slow close speed the problem persists, then it might be that the parison thickness is too thin at the handle area of the jerry can or that the bottom flasher area is not enough to form a strong welding line, therefore, try increasing the thickness profile at these points in the parison so that when the mold closes, there is sufficient material to support the welding.

If the tearing keeps happening after implementing these two solutions, then the problem might come from a poor cooling system design of the mold.

4. Surface wall defects

From almost unnoticeable defects like tiny black spots, to larger ones like horizontal ring-like lines, vertical streaking lines, wall bubbles, and rough, rippled or “orange peel” like surfaces, these can all affect your bottles and appear due to many different reasons.

Black spots

Black spots can be caused by foreign matter or old resin (which has already degraded) inside the extruder die head that contaminated the melt and resulted in different colored spots on your jerry can or bottle. Sometimes, the foreign matter or old resin might be stuck inside the die bushing and causes a distortion or vertical line in the extruded parison, thus marking streaking lines in the product; the solution to this is to find where in the die head the contamination is and clean it thoroughly.

Wall bubbles

As for wall bubbles, these are caused by moisture or water particles condensed in the cold resin due to warm and high humidity climates. To avoid this, you can install a hopper dryer or try to keep the resin warm to evaporate the condensed water before it goes into the extruder hopper; also make sure cooling water flow in the extruder feed opening is not so high.

Horizontal ring-like line

When a horizontal ring-like line is formed around your drum or jerry can, it means the parison thickness difference between two consecutive points is too large, hence, the parison thickness controller will move the die or die mandrel too fast, resulting in a ring-like line showing on your product. To prevent this, gradually increase/decrease the thickness between the profile points, also keep the thickness of the first and last profile points the same or very close.

Rippled surface or orange peel

A rough surface that seems rippled or like orange peel, is caused by the parison wall coming into contact with the cold mold surface two times intermittently instead of just once, therefore, prematurely solidifying the wall before it is blown and then stretching it a second time, which does not allow the parison wall to be smoothed out. This situation can happen especially with oval shaped jerry cans and bottles because the parison is too narrow, so the pre-blow is set high in order to expand it and get an oval shape-like parison before the cycle blow. To solve this, try using a bigger die mouth so you can reduce the pre-blow, the oval shape needed for the bottle will be formed with the cutting and sealing unit of the blow molding machine.

5. Uneven Radial Wall Thickness Distribution

An even wall thickness distribution of your jerry can, bottle or drum´s wall is very important to avoid excessive shrinkage of the product and overall bad quality. How does this happen? A product with an uneven radial thickness will have a thinner side that will be cooled down faster than the one with wider thickness, therefore requiring a longer cooling time otherwise the bottle will shrink too much.

To solve this, try aligning the die mandrel(pin) and the die until the extruded parison looks straight. Because parisons with bigger diameters are easier to control than narrower ones, you can also try to increase the die mouth diameter and reduce the pre-blow of the parison as well.

Laser Alignment, Alignment Lasers or Aligning Lasers – What’s the Difference?

Laser Alignment, Alignment Lasers or Aligning Lasers – What’s the Difference?

Laser Alignment, Alignment Lasers or Aligning Lasers – What’s the Difference? – Here at OASIS, we often receive requests for “laser alignment” services. However, this term can apply to several similar, but distinct solutions. In this post, we provide a brief overview of the various tools and technologies that can fall under the category of laser alignment. In future posts, we will delve further into laser alignment tools and describe the applications where each solution excels.

In our field of industrial precision alignment, laser alignment is a generic term used to describe the process of aligning machines using lasers. This term is much like the one used to describe machinery alignment performed using optical instruments, often called optical alignment. Laser alignment can be performed using alignment lasers or other portable coordinate measuring machines such as laser trackers. Laser trackers use laser technology to measure 3-dimensional coordinates quickly and with a high degree of accuracy. The alignment data gathered can be converted to geometrical points, planes, spheres or cylinders using a 3D metrology software solution. These features can then be referenced to defined datum for position, form, parallelism, perpendicularity and more. In the hands of skilled metrology engineers, portable 3D metrology tools are an innovative solution for the laser alignment of industrial machines.

Laser Alignment, Alignment Lasers or Aligning Lasers – What’s the Difference?

Alignment lasers are specialized laser instruments specifically designed to perform industrial alignment tasks. There are many brands of alignment laser systems for all types of industrial applications including shaft alignment, and belt and pulley alignment just to name a few. Typically line or point lasers can be used for planar, rectilinear or perpendicular alignments of machine components. Alignment lasers are most often sold loaded with the programs required to perform their various capabilities. Alignment lasers do not however, provide true 3D coordinates or points, but rather provide the relative alignment of their components (emitter and receiver). Learn more about the causes of machine alignment.

The process of aligning lasers can also fall into the category of laser alignment. In this case, the intended meaning is the act of making alignment adjustments to specialized laser equipment or positioning lasers within an industrial process. Larger equipment or modular laser systems require a certain level of alignment in order to function as intended.

This post covers only a small part of the world of laser alignment. Please check back for more on the various tools, technologies and applications that can fall under the category of “Laser Alignment”. If you would like to discuss your equipment alignment needs and would like a site visit to your facility, please contact the OASIS Service Center nearest you.

Following the roll forming road map

Following the roll forming road map

Following the roll forming road map – Roll forming specialist David Rostocil doesn’t believe in “black magic.” People say that the best roll formers have to gain a “feel” for the process, but Rostocil doesn’t think of it that way.

“You have to take the black art out of it,” he said. “We don’t want to just have a feel for it. We want to gauge the rolls. We want to know what we have.”

That’s the idea behind Rostocil’s forming seminars. As senior technical performance specialist at Roll-Kraft, he has held numerous events, organized by his Ohio-based employer as well as by organizations like the Fabricators & Manufacturers Association International®.

A 40-year industry veteran, Rostocil spent 20 of those years at a custom roll form facility. As he tells the story, he didn’t learn the craft by gaining a “feel” for the machine. He learned by listening to his mentors, the “old engineers” who taught him the ropes and talked about specifics, like what to do and what to avoid to operate an efficient rolling mill, setup after setup.

The Destination and Vehicle

“Sometimes the people who run these machines are seen as not very technical,” Rostocil said. “Sometimes they don’t have drawings. But how can operators know where to go if they don’t have drawings? They may need to be trained or attend a seminar, but it doesn’t take long with the proper training. They learn very fast.”

In effect, the print gives the operator the destination. It identifies the dimensions, material grade, material thickness, radii, and the key control passes. Every set of tooling usually has at least two key control passes, and depending on the severity of the formed section, the operator could have multiple passes that need the proper amount of overform in each to accommodate for material springback.

The setup chart (see Figure 1) is the operator’s vehicle that gets him to the destination. Setup charts should include not only the basics—number of passes, rolls and shim specs, flange gauging points, as well as inboard and outboard spacer dimensions—but also operator notes describing setup intricacies as well as lessons learned from previous runs.

For instance, say a job requires side-roll stands. Before the first pass, the setup sheet might include an explanation, “Mount side-roll stand before the first pass; use edging rolls to keep return legs even.” Additional notes might include something like, “Excessive pressure on passes 9-12 will cause leg heights to become short.”

As Rostocil explained, it’s difficult to give too much information on the setup chart. The more complete the chart is, the smoother an operator’s roll forming road trip will be.

The Road Map

If the print is the destination, and the setup chart represents the vehicle, a documented standard operating procedure is the road map.

The procedure should involve setting the rolls on the machine, gauging the rolls to ensure the distance between them matches the thickness specified on the setup chart, and checking the side clearances and roll alignment without material in the rolls.

(To troubleshoot one pass that is out of alignment, a technician should pull the tooling off and gauge it on a surface plate, Rostocil said. The machine itself may be perfectly aligned; the problem may lie with the tooling. Measuring both the machine and the tooling can help pinpoint the cause of the misalignment. For more on alignment, see the Roll Forming Maintenance Tips sidebar.)

Check the roll spacing. The operator inspects all the rolls to make sure the space between the upper and lower tools mirrors what’s shown on the part print. To do this, the operator places a piece of white paper behind a roll set, then places a mirror in front of the rolls and tilts it 45 degrees. This gives him a good view of the space between the rolls, which should match the part profile on the print (see Figure 2). If it does not, the operator needs to adjust the tooling accordingly, by using shims to align the rolls.

Alternatively, an operator can just crack the nut on the shaft and insert a horseshoe, or split, shim without taking the tooling off the machine. If the operator does this, he will need to double-check the alignment using a feeler gauge. “But watch out,” Rostocil said. “Those horseshoe shims can work their way out at high speeds, and you can lose your alignment anyhow.”

Check the entry table height. Next comes what Rostocil said is a step many operators forget: using a straight edge to make sure the entry table is at the proper height, aligned with the entry rolls (see Figure 3). “Many assume the entry table is always going to be perpendicular and parallel going into the entry rolls. If the table is not perfectly in line with the tooling, the material will skew and twist at the end of the machine. Many times operators focus on the rolls near the end, when the problem really starts at the entry table.”

Following the roll forming road map

Set the side-pass stand height and center the side rolls. Similarly, if the job’s tooling set uses side rolls—which are mounted on a vertical axis and located between passes to help maintain the profile shape—an operator should check the stand height with a dial indicator.

To center the side rolls, the operator can use a straight edge to measure from the flat surface on the roll form machine, from the pass just before or after the side-pass stand. The distance on both sides of the roll should be the same.

Measure the material thickness. To find the most efficient route, an operator needs to know exactly where he’s starting out, and this is where the material comes into play. An operator should measure the actual thickness of the coil material that will be formed. If the setup chart and print says 16-gauge material, an operator may just set up the material for 0.060 in. Yet the actual material may be a little thicker or thinner.

“You need to make sure the tooling will accept the thickness of material that’s coming into the machine,” Rostocil said.

“If you don’t know exactly what material thickness is being formed into the machine, how do you know where you’re going?”

When setting the rolls with the material, the operator should make sure the feeler gauge has a snug fit between the upper and lower shafts (see Figure 4). “It should be a little snug,” Rostocil said, “and it should feel the same on both the inboard and outboard sides of the machine. You need to make sure you have the proper clearances for the material and for the radii being formed, and make sure everything is set.”

Feed, jog, and adjust. Even on a brand-new machine, the roll stands’ gearbox components (bearings, housing and adjustment nuts, etc.) shift upward once material feeds into the rolls. To compensate for the bearing slop and other movements, an operator inserts a feeler gauge between the top and bottom rolls to reset the roll position to the proper gap. Where to put the feeler gauge depends on the tool profile, but usually the operator places the gauge to ensure the roll remains as parallel as possible on the shaft.

Still, the worst thing an operator can do here is to adjust quickly down “hard” on the gauge until the material feed slows. “This is where you get the squeeze-out,” Rostocil said. “Squeeze-out” occurs when the top and bottom rolls, gapped too close together, squeeze and distort the material, causing twist, bow, camber, and other issues during production. Instead, operators jog the material 1 or 2 in. to allow material to seat in the rolls, then readjust and jog again as necessary. Then it’s on to the next roll.

“For newbies, this can take quite a while, maybe up to 20 minutes per stand,” said Rostocil. “But once you get accustomed to it, you can adjust the roll fairly quickly.”

Run test pieces, measure, then add the straightener and cutoff. The number and length of test pieces depend on the job, but regardless of the application, operators need to measure the profile, compare it to the print, make the appropriate adjustments, then document them in the setup chart.

Once the piece meets specifications, operators then can add the straightener as well as a cutoff system. As Rostocil explained, the straightener is there to account for material and process variation, and it shouldn’t need to straighten the section coming off the mill significantly. In fact, ideally, the section should emerge from the mill as straight as possible. “Otherwise, you might have trouble running a straight profile during production.”

Benefits of Documentation

Material quality matters in any metal forming process, and this of course includes roll forming. But as Rostocil explained, it’s not the operator’s job to complain about the material. “It’s his job to help document the process and make it work.”

This includes documenting material thickness variation, the adjustments those variations require, and even the time those adjustments take. It’s one reason that measuring material thickness periodically throughout the run is so important. He can then share that documentation with supervisors and purchasing personnel.

“I worked at a roll form company for 20 years, and spending a few cents more for better material gave us more than twice the production,” Rostocil said.

Similar thinking goes for tooling choices and the number of stations (passes) on a mill. A roll form operation may try to “make it work” with fewer-than-optimal roll stands, sometimes adding some side rolls to ensure proper forming. All this adds to the setup time, though, and can make the process unpredictable. Documenting all this may help make the case for more roll stations and a better tooling setup.

If the operator records where variation occurs—from poor material or a suboptimal tooling setup—and includes all the subsequent adjustments that variation causes, he ultimately can help the company make better decisions. And those decisions should be based not on some special black magic or a feel for the process, but actual process data that shows what’s happening at the roll forming mill—and why.

Roll Forming Maintenance Tips

To ensure the machine stays in good working order, technicians should perform a comprehensive integrity check and alignment. If an operator performs basic preventive maintenance tasks, such as applying grease and tightening bearing nuts, technicians shouldn’t have to check alignment very often, sometimes just once a year. But as always, maintenance frequency depends on the application.

Roll form machine maintenance includes ensuring bearings on the stands are in good working order, are preloaded properly, and give the proper “float” to accept the shafts. A tech may also inspect the inside diameter of the shafts using a telescoping or boring gauge and inspect the outside diameter with a micrometer to ensure it’s within tolerance (usually within -0.001 in. per 1 in. of the shaft OD).

For drive stands, where the inboard stand incorporates the transmission, the technician will inspect the bearing blocks and tighten and adjust by machining them or using shims to ensure the assembly has a tight fit and the slide can move the top shaft up and down with precision.

The top shoulder also needs to be lined up with the bottom shoulder, often by using sizing rolls of equal width as a “fixture,” slid along the shaft against the top and bottom shoulders. This gives the tech more points of contact when using a straight edge.

Once the tools and spacers are on the machine, the technician can place a straight edge on both sides of the rolls to ensure the top and bottom shafts are parallel. If spacers are too narrow for a straight edge, a tech may insert a drill rod against the rolls to check for parallelism.

A technician also checks for shaft parallelism by placing a feeler block between the shafts, being sure alignment is the same on both the inboard and outboard sides.

Best Laser Cutters for Small Businesses in 2023

Best Laser Cutters for Small Businesses in 2023 – Small businesses frequently use laser cutters for a range of tasks; they’re great for jewelry, signage, and prototyping. Factors such as size, power, and price are important considerations for a small business owner who is looking to buy a laser cutter. To help you make an educated choice, we’ve assembled the following list of the top 12 laser cutters for small businesses in 2023:

1. xTool M1

The xTool M1 has distinguished itself as the first desktop hybrid laser and blade-cutting machine. It doubles as a laser cutting and engraving machine as well as a blade cutting machine. Depending on the materials you wish to cut or engrave, you can choose between two models: the 5W and 10W versions. The xTool M1 can be applied to a wide variety of materials including metal, glass, and wood. For materials such as vinyl, its laser may not be the best option because burnt vinyl releases toxic fumes. This is where the blade becomes valuable. In one pass, the xTool M1 is powerful enough to cut through 8 mm of basswood. Some hardware specifications for this hybrid machine include a carving precision of 0.01 mm, a laser spot of 0.08×0.08 mm, and a work area of 385×300 mm.

What could be seen as P2’s weakness is actually one of this laser cutter’s strengths. xTool has a history of offering interesting add-ons, and the P2 is no different. You can increase the size of the workspace height using a Riser Base. The P2 is speedy too, running at 600 mm/s, it cuts 18mm basswood in one pass with ease.

The xTool P2 is cheaper than the Glowforge Pro (below) but quite comparable overall, despite having a slightly more powerful laser. One thing of note, P2 has a precision of 0.3mm while Glowforge has a macro camera that can reach 0.1mm levels. I have both laser cutters and am currently testing P2, and can say both machines are excellent. With P2 the advantage is it fits into xTool’s wider ecosystem of add-ons, ensuring that overall, this laser cutter can do pretty much anything, including rotary engraving (purchased separately).

REASONS TO AVOID

Ideally needs the Air Filter accessory

Glowforge Pro does for laser cutters what Cricut has done for craft cutters; this is a beautifully designed ‘laser printer’ that removes the mess and fuss and packages it all in a clean and approachable device, making it easily the best laser cutter around at the moment (for a price). This model is the top Glowforge laser cutter, while the brand has a the medium Plus edition and a slightly less powerful Basic model.

The Glowforge does the same cutting and engraving as many of the best laser cutters on my list, but its design keeps any mess inside the machine (a filter sucks away any dust and debris into an external air filter). Designs are sent to the machine via a bespoke app, and the Glowforge machines support Windows, Mac and tablet devices.

The Glowforge Pro uses a high-spec Class 4, 45 watt laser which is the most powerful you can get outside of an industrial use. (The Plus and Basic use a 40 watt, Class 1 laser, which is still more powerful than most on this list.) In my Glowforge Pro review this laser cutter impressed with its speed, ease of use and an excellent design app. It does, however, ideally need to be used with the Glowforge Air Filter accessory.

It’s this ease of use and clean approach to laser cutting and engraving that ensures the Glowforge makes it to No.1 on my list. It looks like a standard printer but can engrave everything from metal to wood and tiles to paper and leather – it’s perfectly suited to every task that requires accurate cutting too, from costume creation to model work. This Pro model comes with a ‘passthrough’ slot for large lengths of material, making it an ideal wood laser cutter – you can even make furniture. The results are always great, making this the best laser cutter for small business overall.

Types of Heavy Construction Equipment and Their Uses

Types of Heavy Construction Equipment and Their Uses

Types of Heavy Construction Equipment and Their Uses – In 2018, people bought more construction equipment than ever, thanks to a growing number of commercial, residential, and industrial projects that require heavy-duty tools and machinery to get the job done. Whether you’re working hard at a construction site, conducting road maintenance on a busy highway, or searching for the right tool for your large-scale landscaping project, there is a piece of equipment out there to make the work both easier and safer.

In this guide, we’ll discuss some of the most common types of heavy equipment and their applications.

1. Articulated Trucks

Articulated trucks are a type of heavy-duty dump truck that many praise for their versatility and adaptability. Unlike rigid haulers, articulated trucks consist of both a cab and a narrow trailer, or dump box. The two connect via a pivoting hinge. They are ideal for applications on challenging worksites with little to no paved roads, steep slopes, slippery or sandy surfaces, or low ceiling height.

You’ll find these at many types of job sites, including:

  • Mining
  • Recycling and scrapping
  • Material and aggregate hauling
  • Utility construction

Always match an articulated truck rental or investment to the size and type of load it will be hauling.

2. Asphalt Pavers

Asphalt pavers are usually accompanied by dump trucks carrying asphalt, which moves the material into the paver. Once it’s full, the asphalt paver uses dispersion augers to disperse the asphalt across a leveled surface. Then, it rolls it flat with a hydraulic cylinder, creating a solid, stable place to drive or walk.

You can use these pavers to lay asphalt on places such as:

  • Public and private roads
  • Driveways
  • Parking lots
  • Bridge decks
  • Recreation courts
  • Industrial sites
  • Building construction

Asphalt pavers are available in a variety of paving widths and speeds.

3. Backhoe Loaders

A backhoe loader is a single piece of equipment that can function as either a backhoe, a tractor, or a loader. The durable backhoe is located on the back of the machine, while the loading mechanism is in the front. The central operating machine is the tractor.

Because it’s capable of handling so many different jobs, you can use a backhoe loader for things like:

  • Farming
  • Excavation
  • Construction
  • Hauling
  • Digging

4. Boom Lifts

Boom lifts are a type of aerial lift mechanism. You might have also heard of it referred to as a basket crane or cherry picker. These attachments allow workers to reach elevated work areas but are not limited to only industrial or construction projects.

They are versatile and used across a variety of industries, including:

  • Forestry
  • Construction
  • Painting
  • Farming or harvesting
  • Window cleaning
  • Fire fighting

There are several different types of boom lifts, including telescoping and articulating. Boom lifts are suitable for one or more workers at a time, depending on the size of the bucket or platform.

5. Cold Planers

Cold planers are a type of heavy equipment for construction that utilize rotating drums and carbide cutters to mill pavement or asphalt. You can use a cold planer for either minimal or in-depth removal. Because pavement and asphalt milling creates a lot of dust, most cold planers utilize a water system to maintain a clean and safe work environment.

There are many reasons why one might use a cold planer to mill a roadway, such as:

  • Recycling asphalt for new roads or other projects.
  • Creating rumble strips for use along highways.
  • Repairing existing damage.
  • Smoothing land before paving to minimize any future potholes or cracks.

Types of Heavy Construction Equipment and Their Uses

Like most heavy-duty equipment, cold planers are available in various sizes to suit several types of projects. Smaller machines are easily navigable and suitable for minor milling projects, while large machines are more challenging to navigate but can tackle large-scale projects with ease.

6. Compactors

Plate compactors use a heavy, vertically vibrating plate to crush and compact a surface into a level, flat area. The force behind the plate and the quick and repetitive movements work to break down and compact debris. In addition to industrial applications, you can also use a plate compactor to flatten an expanse of soil, sand, or gravel.

Depending on your application, choose between a single, reversible, or heavy-duty plate compactor:

  • Single plate: Single plate compactors are suitable for small-scale asphalt or building projects, like home renovations or laying sidewalks and driveways.
  • Reversible plate: For projects that require more versatility, reversible plates operate in multiple directions.
  • Heavy-duty plate: Heavy-duty plate compactors are the best option for large-scale industrial, construction, or roadway projects.

7. Compact Track and Multi Terrain Loaders

You can use both a compact track loader and a multi-terrain loader to transport heavy worksite materials. The two machines look and function similarly, but they are not the same. Compact track loaders are intended for more rugged, heavy-duty use than a multi-terrain loader. However, that’s not to say a multi-terrain loader isn’t powerful or effective — it’s just better suited for terrains that require more care, like sod or turf, while the compact track loader can handle more challenging surfaces like rocks, mud, and sand.

While each offers an unparalleled level of versatility and traction, you must consider job site conditions when choosing a piece of loader equipment.

8. Dozers

Bulldozers, also known as track-type tractors and crawlers, are critical pieces of machinery for several types of projects, including:

  • Farming
  • Land clearing
  • Road construction
  • Demolition
  • Home renovation

Dozers use a heavy-duty track to move with blades that can push rocks, building materials, debris, sand, snow, or dirt. There are a few different types of dozer blades, including the flat, edgeless straight blade, curved universal blade, and semi-universal combination blade.

9. Draglines

Draglines are a type of large-scale excavator used for reaching extensive depths at surface mining sites, above ground excavation sites, and more. Draglines function using a tall boom arm equipped with wire-based drag and hoist ropes. These ropes work together to move an attached bucket to and from its point of application. Once in place, the dragline operator controls the bucket so it can collect and move debris by dragging it across the surface.

Because they are so tall and heavy, many draglines are assembled on the worksite rather than transported, though there are smaller models available.

10. Drills

Rotary blasthole drills are a type of heavy equipment used for drilling holes at mine sites. Autonomous drills are a growing trend among equipment handlers because they have built-in features that can help you complete projects quickly and safely.

For example, automated drills today might feature:

  • Depth tracking
  • Built-in cameras
  • Automatic leveling, retracting, and drilling
  • HVAC systems to cool while limiting dust exposure

Non-automated drills offer just as much power, but these features can enhance the comfort and safety of your works as well as the overall productivity of the equipment.

1. Excavators

Excavators are important and widely used equipment in construction industry. Their general purpose is to excavation but other than that they are also used for many purposes like heavy lifting, demolition, river dredging, cutting of trees etc. Excavators contains a long arm and a cabinet. At the end of long arm digging bucket is provided and cabinet is the place provided for machine operator. This whole cabin arrangement can be rotatable up to 360o which eases the operation. Excavators are available in both wheeled and tracked forms of vehicles.

2. Backhoe

Backhoe is another widely used equipment which is suitable for multiple purposes. The name itself telling that the hoe arrangement is provided on the back side of vehicle while loading bucket is provided in the front. This is well useful for excavating trenches below the machine level and using front bucket loading, unloading and lifting of materials can be done.

3. Dragline Excavator

Dragline excavator is another heavy equipment used in construction which is generally used for larger depth excavations. It consists a long length boom and digging bucket is suspended from the top of the boom using cable. For the construction of ports, for excavations under water, sediment removal in water bodies etc. can be done by dragline excavator.

4. Bulldozers

Bulldozers are another type of soil excavating equipment which are used to remove the topsoil layer up to particular depth. The removal of soil is done by the sharp edged wide metal plate provided at its front. This plate can be lowered and raised using hydraulic pistons. These are widely used for the removal of weak soil or rock strata, lifting of soil etc.

5. Graders

Graders also called as motor graders are another type of equipment used in construction especially for the construction of roads. It is mainly used to level the soil surface. It contains a horizontal blade in between front and rear wheels and this blade is lowered in to the ground while working. Operating cabin is provided on the top of rear axle arrangement. Motor Graders are also used to remove snow or dirt from the roads, to flatten the surface of soil before laying asphalt layer, to remove unnecessary soil layer from the ground etc.

6. Wheel Tractor Scrapers

Wheel Tractor Scrapers are earth moving equipment used to provide flatten soil surface through scrapping. Front part contains wheeled tractor vehicle and rear part contain a scrapping arrangement such as horizontal front blade, conveyor belt and soil collecting hopper. When the front blade is lowered onto the ground and vehicle is moved, the blade starts digging the soil above the blade level and the soil excavated is collected in hopper through conveyor belt. When the hopper is full, the rear part is raised from the ground and hopper is unloaded at soil dump yard.

7. Trenchers

Trenchers or Trenching machines are used to excavate trenches in soil. These trenches are generally used for pipeline laying, cable laying, drainage purposes etc. Trenching machines are available in two types namely chain trenchers and wheeled trenchers. Chain trenchers contains a fixed long arm around which digging chain is provided. Wheeled trenchers contains a metal wheel with digging tooth around it. To excavate hard soil layers, wheeled trenchers are more suitable. Both types of trenchers are available in tracked as well as wheeled vehicle forms.

8. Loaders

Loaders are used in construction site to load the material onto dumpers, trucks etc. The materials may be excavated soil, demolition waste, raw materials, etc. A loader contain large sized bucket at its front with shorter moving arm. Loader may be either tracked or wheeled. Wheeled loaders are widely used in sites while tracked or crawled loaders are used in sites where wheeled vehicles cannot reach.

9. Tower Cranes

Tower cranes are fixed cranes which are used for hoisting purposes in construction of tall structures. Heavy materials like pre-stressed concrete blocks, steel trusses, frames etc. can be easily lifted to required height using this type of equipment. They consists mast which is the vertical supporting tower, Jib which is operating arm of crane, counter jib which is the other arm carries counter weight on rear side of crane and an operator cabin from which the crane can be operated.

10. Paver

Paver or Asphalt paver is pavement laying equipment which is used in road construction. Paver contains a feeding bucket in which asphalt is continuously loaded by the dump truck and paver distributes the asphalt evenly on the road surface with slight compaction. However a roller is required after laying asphalt layer for perfect compaction.

Roll Former Alignment

Roll Former Alignment

Are you experiencing difficulties holding tolerances in length or material straightness of your roll formed product? How about an angular or dimensional cross-sectional problem?

Roll Former Alignment – Roll Former misalignments can be very hard to find. Immediately everyone wants to start by moving the
guides, forming roll spacers or adjusting pressures. The proper way to determine where the problems are originating from is to start with a complete footprint of the entire line, from uncoiler to finished product. Every component should be set to a centerline or an offset centerline, then each component needs to be square, parallel, and perpendicular to each other, as well as centered.  If the mill has a two piece base it also needs to be level and square.
If any of the components are out of square to one another or too far off centers, then it can apply pressure on the product while feeding. It also causes it to rise or warp from one component to the next, which may also be a little misaligned, and by the time it reaches the roll form mill it has pressures applied to it from two or more directions.
Maverick Systems technicians can perform a laser inspection of the entire line. Once the inspection is complete, you will have a footprint of any and all misalignments throughout the length of the roll former line. The footprint allows our technician to determine which components are creating the alignment issues and begin making adjustments to correct them.

Here are some of the problems you may be encountering with the finished product due to misalignment of the Roll Former Line.

Camber

Camber is the variation of a side edge from a straight line, the gradual deviation from straightness of the edge of sheet or coil stock caused during the slitting operation. Camber is the edgewise curvature, a lateral departure of a side edge of sheet or strip metal from a straight line. Extreme camber contributes to curve, bow, and/or twist in the finished part.
Roll Former Alignment

Bow

Bow is the variation from a straight line in the vertical plane of a roll formed piece. It can be either cross bow or longitudinal bow.

Curve (also referred to as Sweep)

Curve is the variation from a straight line in the horizontal plane measured after the part has been roll formed. Causes of curve included incorrect horizontal roll alignment and uneven forming pressure. See bow, camber, sweep, and twist.

Twist

Twist is a term used to define parts when they resemble a corkscrew effect. This is often caused by excessive forming pressure in the final formed part. Twist should be less than 5° in 10 feet of roll formed parts. See bow, curve, camber, and sweep.

Another issue you may be experiencing is the length of leg size being different from one side

to the other or the size deteriorates as you go down the length of the part.

Leg

The leg is typically a 90% bend that is used for interconnection, mounting, or added structural support of the final product.

Length of the leg

A good rule of thumb is the leg length should be three times the thickness of the material.
Maverick Systems can provide a solution to all your alignment needs.
