Injection Molding Guide These settings are to be used only as a guide. This is a typical injection molding temperature profile based on the Test Machine (conditions based on a 75 ton machine with a general pure screw – L/D 17 – ? 35mm). The optimal run conditions for specific equipment will vary depending on the machine and mold design
