Injection pressure should be set considering the mold construction and other molding conditions, but generally 49 to 118MPa will be enough. Reny molding recommends relatively high resin temperature of 130 . Reny has good flow property, so burr might occur depending on the molding condition. Avoid molding only by the primary pressure, and use

Injection molding is a process in which the hot polymer is injected into a mold cavity. Heat is removed from the polymer in the mold until it is rigid and stable enough to be ejected. Therefore the design of the part and mold are critical in ensuring the successful molding process. For the recent years, the insert molding in injection molding .
