Material Preparation: Plastic pellets are fed into a heated barrel, where they are melted.
Injection: The molten plastic is then injected under high pressure into a mold cavity. The mold is typically made of steel or aluminum and is designed to create the desired shape of the final product.
Cooling: Once the mold is filled, the material cools and solidifies, taking on the shape of the mold.
Ejection: After cooling, the mold is opened, and the finished part is ejected.
Injection molding is highly efficient for mass production, allowing for high precision, repeatability, and complex designs. It’s commonly used for making everything from small components to large parts in various industries.

We offers a variety of finishing options that enhance the appearance, functionality, and durability of molded parts. These finishing techniques can be applied after the part has been molded to achieve the desired final characteristics. Here are some common finishing options for injection molding:
Plastic injection molding creates parts from a single material. Overmolding bonds a soft material (TPE/TPU/silicone) over a rigid substrate for ergonomic grips and seals. Insert molding encapsulates metal inserts (threads, pins, contacts) into plastic to reduce assembly steps. We offer all three processes.
Use plastic injection molding for simple single-material parts. Use overmolding if you need soft-touch grips, waterproof seals, or anti-slip surfaces. Use insert molding if your part requires metal threads, bushings, or electrical contacts integrated into plastic.
Automotive, medical, consumer electronics, aerospace, robotics, and energy industries.
Engineering plastics including ABS, PC, PA66 (Nylon), POM (Delrin), PEEK, PEI (Ultem), PMMA, PP, PE, TPE, TPU, and more. Material selection depends on strength, heat resistance, flexibility, and application.
Most orders can be completed within 15 working days, depending on part complexity and volume.
Yes. Before tooling begins, we provide a comprehensive Design for Manufacturing (DFM) analysis to optimize your design for cost and manufacturability.
