The MAS plastic extruder is perfect for processing A-PET, G-PET, R-PET, PET or PLA both for re-pelletizing and for direct extrusion into final products. The large feed section of the conical extruder supports feeding of both PET flakes (PET bottles, preforms) and pellets as well as sheet regrind. With a combination of venting ports and a feed throat under a high-performance vacuum, the MAS system can process PET and PLA materials without the need for pre-crystallizing or drying.
As the extruder’s intake volume is significantly greater than the discharge volume, an extremely high screw fill level is achieved. This helps to achieve high output values at slow screw speeds and at correspondingly low melt temperatures. This results in excellent color values and minimal IV loss.
When producing an FDA complaint pellet or sheet, the MAS Extruder can be combined with a standard crystalizing and drying system or the advanced KREYENBORG Infrared Dryer.
