Process and Structure of Screw Extruder

[fyitester]

Extrusion molding, also known as press molding, is a molding method that heats and melts the polymer solid material into a melt, and uses the extrusion effect of the screw to push the viscous fluid material through the die to form a continuous body with a cross-sectional shape similar to the die shape. The corresponding equipment is called a screw extruder. https://fyitester.com/process-and-struct...-extruder/
