Plastic Injection FAQs

Plastic injection molding is a manufacturing process used to produce parts in large volume. It involves injecting molten plastic material into a mold, where it cools and solidifies to the configuration of the mold. The process is highly versatile and can produce a variety of parts with complex geometries and surface finishes.

  • Efficiency: Once the initial costs have been paid, injection molding can produce parts at a very low cost due to its high rate of output.

  • Complex Part Design: Injection molding allows for the manufacture of complex and intricate parts, making it a good choice for components that require detailed designs.

  • Enhanced Strength: In injection molding, fillers can be added to the plastic material, reducing its density and adding greater strength to the part after molding.

  • Multiple Plastic Types: Multiple types of plastic can be used simultaneously through the process of co-injection molding, offering greater flexibility in the design and manufacturing process.

Yes, our advanced machinery and skilled team can handle complex part geometries, ensuring the parts are molded to your exact specifications.

While we don't create prototype designs, our in-house mold engineers provide Design for Manufacturing (DFM) and tooling design evaluation capabilities to ensure that the product can be manufactured to your exact specifications.
