The temperatures and processing conditions listed here are intended as guidelines for molders and designers. In some cases, relatively broad ranges are necessary to accommodate variations in compound formulas.
Injection molding is a complex science; best results may only be achieved after several trials. RTP Company’s technical support specialists can assist you with determining optimum settings for your unique compound.
