This extruder can be vacuum-exhausted type according to the different materials.
The screw and barrel are specially designed according to different materials.
Extruder can be Siemens PLC touch screen controlled.

Plastic pellets are fed into the barrel of the extruder and conveyed by the screw, the heaters which are outside of the barrel of the extruder as well as the friction from the rotation of the screw melt the plastic pellets into a sheet mold and then placed on a three-roll calender, the produced sheet goes through the bottom and middle roll,wrapping around back of the middle roll and then back to the top roll or other methods as shown in sheet calender picture, these rolls are helpful to take the heat out of the sheet, after the sheet comes off the roll,it moves down the conveyor to the end of sheet line where the edge trimmer cuts the sheet to width as well as a sheet shear cutter to length.
