Four essential factors that affect the quality of plastic injection molding

2018-03-23T13:34:45+00:00

1. Plastic Material The complexity of plastic material properties determines the complexity of the injection molding process. And the properties of plastic materials may vary greatly with different varieties, brands, manufacturers, and even batches. Different properties, in turn, can lead to completely different molding results. 2. Injection Temperature The plastic melt flows into the cooled cavity, and loses some heat [...]
