» Common Causes of Injection Moulding Plastic Deformation

Common defects in injection molding process can be classified in to two ways. They are: 1. Dimensional related 2. Attribute related Dimensional related defects can be controlled by correcting the mold dimensions. But, attribute related defects are generally dependent on the processing parameters. Some of the common attribute related defects are splay marks, sink marks, voids, weld/meld lines
