Q

Overpacking

A

This problem is a typical manifestation of overpacking 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 recommended t...

Q

Warpage Deformation

A

Warpage is macroscopic bending caused by inconsistent shrinkage of various parts of the part. The solution ideas are: achieve uniform cooling of all parts during the cooling stage (cooling water channel optimization), adopt symmetrical layout and isotropic design in structural design (wall thickn...

Q

Silver Streak / Material Flower

A

The essence of silver streaks is that gas/volatile components expand in the melt to form surface defects. The first priority of the solution is always to fully dry the raw material, followed by controlling the barrel temperature to avoid material degradation and gas generation, supplemented by op...
