Extrusion Barrel Alignment & Laser Barrel Alignment

Extrusion barrel alignment is very important when it comes to saving money on needless replacement costs. It is quite easy to justify the costly investment in laser barrel alignment equipment while counting the money being spent by you for wear and tear on essential components. It causes the cost of important parts that require replacement and the down-time that invariably arises during this replacement. It also brings reduction in power consumption when the extrusion barrel gets misaligned.

Relative to the output shaft of the gearbox, the proper extrusion barrel alignment helps the extrusion line last for long. This is caused by the small endurance between the screw and the extruder barrel. It is for this reason; the more large size an extrusion screw has, the more is the importance of proper alignment. Laser barrel alignment, in this regard, significantly prevents misalignment. This operation needs to be implemented when the gearbox gets decoupled from the extruder or the screw is taken away. The most accurate and the fastest method of laser carry out the alignment process within a deviation of not more than 0.001”.

On an average, it takes about 10 hrs for the laser alignment of an extrusion line. However, the time and cost invested on this operation is lesser than the cost paid by you in case the line gets misaligned. Precision Parts Inc or PPI has made a niche in this regard and is well-known for its services like barrel alignment in addition to roller, coupling and pulley alignment. The laser alignment, at PPI, is performed on the CNC and traditional machining centers. The collimated laser system also helps set up the alignment of the tool holders and chucks at the initial stage.
