Our custom injection molding services

Plastic injection molding is designed especially for the mass production of plastic parts by repeatedly
using the same mold. Consistent color, structure, appearance is the features for injection molded parts. Hundreds of thousands of custom parts are produced by machines.
The cost of per part decrease with higher quantity manufacturing runs.

Plastic Injection Molding

Plastic Injection Molding

Plastic injection molding is a manufacturing process that involves injecting high-pressure, molten thermoplastic into a custom mold to create precise parts.

Insert Molding

Insert Molding

Insert molding is an injection molding process in which thermoplastic material is molded around pre-positioned inserts—such as metal pins, threaded fasteners, or electronic components—placed inside the mold.

Overmolding

Overmolding

Overmolding is an advanced injection molding process where one plastic material is molded over another to create a single, unified component.
