Injection molding temperature is critical for plastic injection molding; the proper injection molding temperature ensures product quality and manufacturing efficiency. As an injection mold manufacturer, we will demonstrate mold and melt temperature ranges for plastics and the optimal injection temperature ranges for various plastic materials. The aim here is to inform you of the temperature necessary in the melting and molding of plastic products. Do read on to find out more.
