Characteristics of Injection Molding Technology for Insert

Insert molding (insert molding) refers to the molding method in which the resin is injected into the mold after the pre-prepared different material insert is loaded into the mold, and the molten material is joined and cured with the insert to form an integrated product. Out-sert molding refers to the injection molding process in which a part of a metal plate is embedded.

The above two molding methods are essentially the same, and their characteristics are as follows.

1. The combination of easy formability, bending and metal rigidity, strength and heat resistance can be used to make complex and exquisite metal plastic integrated products.

2. In particular, the combination of insulation of resin and conductivity of metal can meet the basic function of electrical products.

3. The pre-molding combination of multiple inserts makes the post-engineering of product unit combination more reasonable.

4. Inlay products are not limited to metal, but also cloth, paper, wire, plastic, glass, wood, wire ring, electrical parts and so on.

5. For rigid molding products and flexible elastic products on rubber sealing gasket, the complex operation of arranging sealing ring can be saved after the integrated product is made by injection molding on the matrix, which makes the automatic combination of the later process easier.

6. because it is the joint between the molten material and the metal insert, compared with the pressing method, the gap between the metal insert can be designed narrower and the reliability of the composite product is higher.

7. Select the appropriate resin and molding conditions, that is, for products that are easy to be damaged (such as glass, coils, electrical parts, etc.), the resin can also be sealed and fixed.

8. select the appropriate mold structure, the inlay can also be completely sealed into the resin.

9. After the insert is formed, after the core hole is removed, the product with hollow groove can also be made.

10. With the combination of vertical Injection Molding Machine, manipulator, insert assembly device and so on, most of the insert forming engineering can realize automatic production.
