Automatic insert molding system design selection considerations 1, metal insert molding is prone to uneven molding shrinkage, prior to the shape of important parts, size accuracy limit test should be done. 2, the injection process of metal insert is easy to deformation and displacement, should give full consideration to the mold composition and easy to maintain the shape of the metal insert mold design. For the shape of the insert can not change the injection

Features of insert molding injection molding process Insert molding refers to the molding process in which the mold is filled with pre-prepared inserts of different materials and then injected with resin, and the molten materials are joined with the inserts and cured to make products. Injection molding on the substrate refers to the method of insert molding on the local surface of the metal plate. Its characteristics are as follows. 1、The combination of the ease

The selection of insert materials mainly includes four aspects: 1. Hardness; 2. Wear resistance; 3. Strength and toughness; 4. Corrosion resistance. The selection of mold insert materials is mainly based on the batch of plastic products and the types of plastics. The products are ordinary plastics, such as ABS, PP, PC, etc. Pre hardened and tempered steel of P20 type is usually selected. If the batch of products is large, quenched and tempered steel of

1. First, what is insert injection molding? Insert refers to the mold accessories used for inlaying in the mold core. The inserts can be square, round, and sheet type. Like all mold accessories, the requirements for precision are also very high. Generally, there is no finished product and it is customized according to the needs of the mold. Type of insert: insert pin, insert block, insert column, insert ring, etc; Material: SKD61, SKH51, ASP23, SKD11,

Key points for metal insert design of injection molding products The thermal expansion coefficients of plastic and metal are 5~10 times different, so when plastic products with metal inserts are cooled, their shrinkage degrees are different. Because the plastic shrinkage ratio is large, they tightly hold the metal inserts. The plastic inner layer around the inserts is under compressive stress, while the outer layer is under tensile stress, resulting in stress concentration. The following points
