Insert Molding Process

Insert molding is a molding method to make integrated products.

Ⅰ. Definition of insert molding
Plastic insert molding means that after inserting a pre-prepared dissimilar
material into the mold, injecting resin and molten material, and finally
joining with the insert to solidify.

Ⅱ. Characteristic of insert molding
Injection molding on the substrate refers to the embedding method of injection
molding parts on the local part of the metal plate surface. Its features are as
follows:

1. The mutual combination of resin's formability, bending and metal's rigidity,
strength, and heat resistance can firmly produce complex and exquisite metal
plastic integrated products.

2. In particular, the custom injection molded products made of the combination
of resin insulation and metal conductivity can meet the basic functions of
electrical products.

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

4. Inserts are not limited to metal. There are also cloth, paper, wire,
plastic, glass, wood, wire coil, electrical parts, and so on.

5. For the rigid molded products and the bending elastic molded products on the
rubber sealing pad, the integrated products are made by injection molding on
the substrate, which can save the complex operation of arranging the sealing
rings and make the automatic combination of subsequent processes easier.

6. Because it is the joint between molten material and metal insert, compared
with the press in molding method, the gap of the metal insert can be designed
narrower, and the molding reliability of composite products is higher.

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

8. Selecting the appropriate mold structure so that the insert can also be
completely sealed into the resin.

9. With the combination of the vertical injection molding machine, manipulator,
and insert line device, most insert molding projects can realize automatic
production.

10. After the insert molding is formed, it can also be made into products with
hollow grooves after core removal.
