1. The two shapes of the master mold are different, and one type of product is formed respectively, and the two shapes of the male mold are exactly the same.

2. Before and after the mould is rotated 180o in the center, it must match. This inspection must be done during the design process.
3. The total thickness of the front mold panel plus the A plate must not be less than 170mm. Please check the other reference data of this type of injection molding machine carefully, for example, the maximum mold thickness, the minimum mold thickness, KO hole distance and so on.
4. The nozzle of the three-plate die can be designed to be able to automatically release the mold. Special attention should be paid to whether the soft glue outlet is capable of being ejected*.
5. When designing the second injection molding master mold, in order to prevent the secondary mother mold from inserting (or rubbing) and hurting the gel part of the product that has been molded for the first time, part of the design can be avoided. However, the strength of each sealant must be carefully considered. That is, whether there will be deformation of the plastic under a large injection pressure in the injection molding, which may result in a possible second batch injection.
6. When injection molding, the size of the first injection molded product can be slightly larger so that it can be pressed tightly with another male mold in the second molding to achieve the function of the sealant.
7.At the second injection molding, does the flow of plastic impulsion to the product that has been molded for the first time to deform the gel position? If this is possible, it must be improved.
