Thin-wall injection molding defect analysis – dimensional out-of-tolerance
Problems with the mold itself, or improper molding conditions cause the molding shrinkage rate to be inappropriate.
Ways to improve:
In general, changing the holding time and injection pressure (second stage) have the greatest impact on the size.
For example, increasing the injection pressure and increasing the packing pressure can significantly increase the size, reduce the mold temperature, and increase the gate inlet or gate can improve the adjustment effect.
