Plastic Injection Molding Surface Finishing

Proper surface finishing will improve the injection molded parts’ quality. Zhongde offers a wide range of surface treatment options. These efficient surface finishes improve the part’s functions and aesthetic appeal.

1. Clamping
The first step of the injection molding process is clamping. Injection molds are typically made in two pieces. In the clamping phase, the two metal plates of the mold are pushed up against each other in a machine press.

2. Injection
When the two plates of the mold were clamped together, the molten plastic was injected into the mold.

3. Cooling
Put the mold alone, cool and solidify the plastic into the end-use product that can be safely removed from the mold.

4. Ejection
Open the mold, an ejector bar slowly pushes the solidified product out of the open mold cavity.
