Plastics are processed on industrial-sized machines with rack and pinion or linear drives. The benefit of using a machine that utilizes rack and pinion or linear drives is that the machine is able to obtain a perfect surface smoothness. It is also possible to achieve complete transparency on the side surface after processing a material such as plexiglass. This eliminates the extra step of edge polishing, saving a lot of time and work. Processing HDPE materials is also possible at very high speeds, even up to 300mm per second when cutting a 20mm thick board.
