Extruder Alignment Maverick Systems Corporation uses the latest laser technologies and experienced technicians to bore scope and align your extruder barrels. Lasers are the most accurate method of performing alignments with today’s tight part tolerances.
Our technicians have years of experience in the laser alignment field and plasticating industry.
Looking at the diagram below you can visually see how our methods truly align the barrel to the centerline of the output shaft of the gearbox.
Any deviations found at the barrel output are corrected to match the offsets that are found at the barrel input or feedthroat.
We perform our initial inspection of your extruder before we begin the barrel alignment. This inspection covers how the extruder is mounted to the floor and condition of the foundation. Then we check the gearbox and frame for level, and correct if necessary.
Next, we set up our laser equipment and perform the barrel alignment. We document any concerns found during the initial inspection and provide full reports on the final alignment including before and after graphs.

Adjustable Barrel Supports Save Time |
|
|
Time is Money. Upkeep and preventative maintenance on equipment are essential to maintaining a cost effective production line. In todays market, prolonged downtime due to machine breakage or wear can make or break a company. Take for instance the replacement of a 6" barrel and screw. The installation of the barrel is basic and requires only a minimal amount of time. The alignment of the barrel is critical, requiring extra time and care to insure the maximum life of the barrel and screw.

Comparison of Optical Systems and Alignment Lasers |
|
|
 The major players in the extruder alignment field today are optical systems and laser systems. The alignment of extruders has historically been dominated by optical systems. The technology goes back centuries, and while it can be useful, lasers, which are more accurate and user friendly are very quickly overtaking it. While the field has been dominated by optical systems, the drawbacks to the successful use of these products are illustrated in the following excerpts from THE HANDBOOK OF INTELLIGENT SENSORS FOR INDUSTRIAL AUTOMATION

Offsets - What they are and why they matter |
|
|
Setting the laser up on the true center of the axis of rotation of the output shaft/thrust shaft (drive train) reveals errors both vertically or horizontally from the centerline at the feed chamber and the barrel input. This deviation is the called the offset.

Extruder Barrel Alignment |

 The facts about Extruder Barrel Alignment or Bore Scoping
Most extruding machines are built with the thrust bearings, shaft assembly, and the output shaft of the gearbox as one unit. The thrust shaft (which is splined, or keyed) holds and turns the screw, which is the centerline of the axis of rotation. If any of the components are not aligned from the centerline of the thrust shaft there will be friction between the barrel and screw or feed chamber and screw. Sometimes, both situations happen, depending on the amount of error off centerline. If there is friction between the barrel and screw, the amount of wear will increase causing either the barrel or screw (or both) to wear faster increasing your replacement costs dramatically.
