Q

Sprue Sticking

A

This problem is a typical manifestation of sprue sticking 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. It is recommende...

Q

Embrittlement

A

The essence of embrittlement is that the material toughness reserve drops to a level that cannot meet the use requirements. The key to control is the "three temperatures" — processing temperature (avoid excessive degradation), drying temperature (avoid too low leaving residual moisture and too hi...
