3 Principles and 6 Precautions for Two color Mold Design First principle: determine the viscosity of the combination of hard glue and soft glue. In addition, note that the melting point of hard glue should be higher than that of soft glue. Do not melt the hard glue when molding soft glue. 1. First shot: hard glue: PA66+second shot: soft glue: TPE is OK 2. First shot: hard glue: PC/ABS+second shot: soft glue: combination of

In the manufacture of two-color die, it is usually necessary to conduct die opening evaluation, optimize design and process parameters first, so as to avoid unnecessary errors and meet the high quality requirements of mass production. Common problems of two-color mold opening include: parting, crushing, overflow, obvious glue line, etc.   1、 Exotype The reasons for the product parting during the opening of the two-color mold are generally as follows: 1. The temperature difference between

Two color mold refers to the mold in which two plastic materials are injected on the same injection molding machine and molded in two times, but the product is only molded once.
