Problem & Solution

Q

Rough inner and outer walls of heat-resistant polyethylene pipes (Variant: strengthened measures)

A

Pipe wall roughness is caused by low mold temperature or poor surface condition, and needs to be solved from temperature control and mold maintenance. Targeted preventive measures need to be taken in different production scenarios.

Q

Improper production environment control during processing of heat-resistant polyethylene heat-resistant polyethylene (Variant: strengthened measures)

A

The production environment is an important factor affecting the processing quality, and a sound environmental control system needs to be established. In different production scenarios, targeted preventive measures need to be taken.
