Role of Rheology in Injection Molding

Melt Rheology and Its Role in Plastics Processing

  • 1029 Accesses

Abstract

In the injection molding process the objective is to produce a product that is free of voids and sink marks, is not subject to warpage, and has sufficient strength and stiffness for its end use. This requires that the melt flow freely into the mold cavity, and that the final part be reasonably free of residual stresses. At the same time, the product must be produced at minimum cost, and this implies the shortest possible cycle time. The challenge, then, is to produce a good quality part at a minimum cost, and melt rheology plays a central role in meeting this challenge.
