Custom Plastic Injection Molding Service

Mold Design:

The first step is to design the mold that will be used to shape the plastic material. The mold is typically made of steel and consists of two halves, the cavity and the core, which form the desired shape of the final product.

Material Selection:

The appropriate plastic material is selected based on the desired properties of the final product. Factors such as strength, flexibility, and heat resistance are considered during material selection.

Material Melting:

The selected plastic material is melted and brought to a molten state. This is typically done using a hopper and an injection unit, where the plastic pellets are heated and melted.

Injection:

The molten plastic material is injected into the mold cavity under high pressure. This is achieved by using an injection molding machine, which consists of a screw or plunger that pushes the molten plastic into the mold.

Cooling and Solidification:

Once the molten plastic is injected into the mold, it is allowed to cool and solidify. Cooling channels within the mold help to expedite the cooling process.

Mold Opening and Ejection:

After the plastic has solidified, the mold is opened, and the final product is ejected. Ejection pins or plates are used to push the product out of the mold.

Trimming and Finishing:

Any excess material or flash is trimmed off from the final product. Additional finishing processes, such as polishing or painting, may be performed to achieve the desired appearance.

Quality Control:

The final products are inspected for any defects or imperfections. This may involve visual inspection, dimensional measurements, or other quality control techniques.

Packaging and Distribution:

The finished products are packaged and prepared for distribution to customers or further assembly processes.
