Insert Mold

What is insert molding?

Insert molding is a plastic injection molding process that a prefabricated part is inserted into a mold, then injecting the plastic resin, and the molten material is bonded to the insert, cooled and solidified.

Tips on the part design & insert molding mould

1. Material requirements for inserts: hardness, rigidity, shrinkage, melting point

2. The design of the parts shall be convenient for installation and fixation in the mold to prevent the parts from deviation or looseness under the impact of the flowing resin.

3. Manufacturing accuracy and consistency of inserts

4. Select the appropriate mold structure, and the inserts can also be completely sealed into the resin.

5. The shrinkage rate of metal insert molding is not uniform, and the limit test of the shape and dimensional accuracy of the important areas should be done in advance.

6. The metal insert has the possibility of deformation and displacement during the injection process, and the designer should be fully considered about mould construction to help stabilize the metal insert.

What are the Applications for Insert Molding?

Insert molding is used in a wide range of industries for a variety of uses and applications include:

• Home appliance
