Lab Scale TPE Thermoplastic Elastomers

Development status of plastic extruder

by：TENGDA 2023-01-10

Plastic extruders play an important role both as plasticizing granulation machines and molding processing machines. In recent years, plastic extruders have made great progress. At present, the large-scale granulation plastic extruder produced by TENGDA has a screw diameter of 700mm and an output of 36t/h. The main sign of the development of plastic extruders lies in the development of its key parts - the screw.

In recent years, people have carried out a lot of theoretical and experimental research on the screw, and there are nearly a hundred kinds of screws, the common ones are separation type, shear type, barrier type, shunt type and wave type. From the perspective of twin-screw development, although twin-screw extruders have been relatively perfect in recent years, with the continuous development of polymer materials and plastic products, more characteristic new-type screws and special twin-screw extruders will emerge.

In general, plastic extruders are developing in the direction of high speed, high efficiency and specialization. The plastic extruder has good feeding characteristics, is suitable for powder processing, and has better mixing, exhaust, reaction and self-cleaning functions than the plastic extruder, and is characterized by processing plastics and blends with poor thermal stability. It also shows its superiority. In recent years, foreign plastic extruders have developed greatly. Various forms of plastic extruders have been serialized and commercialized, and there are many manufacturers.
