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. There is no need to pre-crystallize or pre-dry the PET or PLA as the feed mechanism is combined with a high-performance Vacuum.
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 a correspondingly low melt temperatures. This results in excellent color values and minimal IV loss. A low thermal load accompanied by very low specific energy consumption high quality product at very low operating cost.
If it is desired to produce an FDA complaint pellet or sheet, the MAS Extruder can be combined with the standard crystalizing and drying system or the advanced KREYENBORG Infrared Dryer since both process have been granted an LNO from FDA for food contact.
