plastic mould and custom injection moulding tips

China Injection Molding In the machine industry, there are many people who are aware that  Plastic Injection Molding  is just as necessary and important as any other machining process. Plastic injection molding equipment should be purchased after considering the following factors: shot volume, tie bar distance, ejector travel, platen dimensions, and tonnage. Shot Volume An injection molding machine’s shot size refers to how much plastic it can inject into a mold cavity during a single molding cycle. In the U.S., the amount of “general purpose polystyrene” (GPPS) is measured in ounces, while in Europe and Asia it is measured in cm3. It is a good idea to always search for a machine that can produce 30-40% more shots than the size of your parts. Platen Dimensions Platens are the tools that hold the  cavity of the mold . Platens are inserted and clamped securely to the mold, which is spaced apart. During the molding process, the two platens are brought together and held under tonnag
