The screw of single screw extruder is generally divided into three sections, according to screw diameter, screw pitch, and screw depth to determine the effective length of the three sections, each by one-third of the general division.
The first section is called conveyor section: materials in the plastics can not be here, but the process of [...]

According to the number of screw, extruders can be divided into single screw, twin screw and multi-screw extruder.
At present, single screw extruder has been the most widely used in the world, in general the extrusion processing of materials.
Due to less heat generated by friction and average material shear, twin screw extruder has greater transmission capacity [...]
