Q

Unreasonable die head flow channel design of heat-resistant polyethylene extruder (Variant: mass production scenario)

A

Die head flow channel design needs to ensure uniform melt distribution and no material stagnation, and the die head should be redesigned when necessary. Targeted preventive measures need to be taken in different production scenarios.
