Abstract

Microcellular injection molding has many advantages such as cost savings, reduced cycle times, and excellent shrinkage properties. However, surface defects on the microcellular injection molded parts-such as gas-flow swirl marks and a lack of smoothness-still remain a challenge. This paper describes a method to improve the surface quality of microcellular injection molded parts.
