Analysis Of The Causes Of Shrinkage And Depression Of Injection Molded Products
Analysis of the causes of shrinkage and depression of injection molded products In the process of injection molding, shrinkage and depression of products is a relatively common phenomenon. The main reasons for this situation are. 1. Machine aspect.
