Product Description

Products Description

Usage:

Extruder is used to produce all kinds of pipes, plates, profiles, pelletizing production lines.

Different types of raw materials use extruders with different structures. The extruders are mainly divided into single screw extruders and twin screw extruders. The single-screw extruder is mainly used for processing PP,PE,PET materials, and the twin-screw extruder is mainly used for processing PVC materials.
