We attended and exhibited at NPE2018 with Sumitomo (SHI) Demag! There were over 65,000 manufacturing professionals from every segment of the plastics industry and its vertical markets in Orlando, Florida in May 2018.
Sajar Plasticsprovided our gasassist injection molding system for injecting and cooling the HDPE pellets. It is a process where we heat the tool up during injection and cool it down rapidly during cooling while concurrently packing out the part for no sink utilizing a nitrogen gas. Our Rapid Heat-Rapid Cool with Gas Assist process achieves a Class A type surface without sink. Adding the Heat and Cool portion to the molding of the part with Gas Assist can take your designs to the next level and eliminate paint! We can also achieve this with glass-filled materials. There are many methods to achieve the heating and cooling of the tool. Some of those methods are Hot Oil, Steam, High-pressure hot water, and Induction.
