Typical Defects of Injection Molding Products - Causes and Countermeasures
We will introduce the causes and countermeasures for each case, including hiccups, voids, short shots, and burrs.
Shrinkage caused by the contraction of resin during curing pulls the interior, resulting in a depression on the surface of the molded product. The main cause is the variation in shrinkage due to differences in the thickness of the plastic. In response, measures such as lowering the resin temperature and injection speed can be taken. This document introduces typical undesirable cases in injection-molded products, including shrinkage, voids, short shots, and burrs, along with their main causes and countermeasures, using photographs for illustration.
