Screw Combination in the Technology of Twin Screw Extruder

Screw combination is the key to the development of extruding process. Co-rotating twin screw extruder mainly with a mixing extrusion, screw combination need to take into account of the shape of the main performance and accessories, feeding sequence and location, the location of vents, barrel temperature settings and so on. At the same time, with the various categories of mixture, it is obvious that there is a variety of combinations. The current research mainly depends on a combination of design experience. Nevertheless, the screw combination of twin screw extruder has its own portfolio and basic laws to follow.
