High Consistency Rubber (HCR) silicone injection molding requires special considerations to manufacture quality parts. The selection of the press, mold design, and gate design are integral to success. HCR silicone processing poses unique challenges when compared with organic polymer based rubber compounds. Part shrinkage, air entrapment, and hot tear issues are examples of processing issues to be considered. Bonding strategies and techniques for metal and plastic substrates are addressed in detail.
