Q

Ejector Pin Sticking / Breakage

A

This problem is a typical manifestation of ejector pin sticking/breakage in '2079851475616104452; the core of the solution lies in eliminating the root cause of the defect through systematic optimization of process parameters (temperature, pressure, speed) and rationality checks of mold design. I...

Q

Parting Line Flash

A

The root cause of flash is that the mold-opening force generated by the cavity internal pressure exceeds the closing force of the clamping system. The logic chain of the solution is: first reduce the cavity pressure peak through process adjustment, then check and repair the clamping system to ens...
