Q

Haul-off slipping

A

This problem is a typical manifestation of haul-off slipping in extrusion molding. The core of the solution lies in eliminating the root cause of the defect through systematic optimization of process parameters (temperature, speed, pressure) and precision correction of the die/sizing system. It i...
