common questions in plastic injection 3
21. Setting of release.
22. Importance of setting the release position
24. Main advantages of gas assisted injection molding (GAM)
28. It is easy to crack when the four columns of the electrical shell are screwed
29. Product deformation
The product deformation is mainly caused by the imbalance of heat shrinkage, or by the internal stress of the product itself.
If the raw material is not dry enough, the product is uneven in thickness, the mold exhaust is poor, and the raw material is easy to decompose, it may cause product bubbles. Fully dry, increase the mold exhaust, and minimize the uneven rubber thickness.
