The Inherent Defects of Injection Molding Products and its Special Processes

Abstract:

In this article, some common defects, which are caused by material properties, and the mechanism of the defects occur are introduced. Author introduces how these defects are treated in conventional process, meanwhile, points out the disadvantages of the process. For the disadvantages, several special processes are introduced, including gas-assisted injection molding, rapid variotherm injection molding and hot runner technology, and their mechanism and advantages.
