As a common extruder equipment, the single screw extruder is used in plastic processing industry. What is its principle and structure? Below is the analysis for the single screw extruder from the extruder conveying section, compression section and metering section.

The production process of plastic pipe extrusion should be selected according to the type and size of plastic pipe. Generally, plastic extruders are used to extrude products. However, plastic materials and types of plastic pipes are different, so the principle of molding in production is different. ......

Screw diameter Screw diameter refers to the outer diameter of the screw, represented by D, in mm. Like a single-screw extruder, the screw diameter of a twin-screw extruder is an important technical parameter, and its size indicates the production capacity of the twin-screw extruder to a certain exte......

Processing Technology of Chlorinated Polyvinyl Chloride (PVC-C) Pipe

Here, we’d like to briefly introduce you the function of the production line equipment of PVC pipe as follows:

Feeding area of plastic extruder: the fixed groove depth of screw groove, which is responsible for preheating, plastic solid conveying and extrusion. It must be ensured that the plastic starts to melt at the end of the feeding section - that is, it must be preheated to the melting point. The general......
