Insert Molding

How Does Insert Molding Work?

Insert molding can be processed both vertical and horizontal molding machines:

1. The inserts are loaded into the custom mold manually or robotically.

2. Molten plastic is injected into the mold.

3. The mold opens once cooling and the components are removed.

4. Components are separated from the sprue and inspected.

The Insert Injection Moulding ( Molding) Process

• Firstly, pellet resin is added to a hopper that serves as a material inlet in insert molding process.

• Secondly, the pellets are heated into a liquid in the cylinder, completing the preparation process for ejection during the insert injection moulding process.

• The material from the nozzle in the injection section is then injected into the insert  injection molding section through a pipe inside the mold called the injection port and through further branching channels.

• After the material is cooled and solidified, open the mold and discharge the molded products to the outside.

• In the final refining process, the injection port and flow passage will be cut and the metal insert molding part will be finished.
