A stable molding process is a window across material, mold, part structure and machine condition.

Practical checks

Injection speed, melt temperature, mold temperature and gate location influence flow balance, weld lines, trapped air and burn marks.

Engineering review

Packing pressure, packing time and gate freeze time affect sink marks, dimensional stability and internal stress.

Discussion

If the root cause is wall thickness, poor venting, weak shutoff or wrong gate position, process tuning can only reduce the symptom temporarily.
