Our Plastic Injection Molding Service

  • Dimensional Accuracy

    Injection molded parts of our custom plastic injection molding deliver excellent dimensional precision and tolerances as fine as ±0.005 inches, thanks to precisely machined steel molds and automated processes.


  • Complex Geometries

    Intricate part geometries by our plastic molding services with thin walls, undercuts and complex curves can be molded as the plastic fills the mold cavity under pressure.

  • Material Versatility

    A wide range of plastic polymers from common grades like ABS and nylon to high-performance materials can be molded of our custom plastic injection moulding to meet mechanical, thermal and chemical needs.


  • High Production Volumes

    Once molds are fabricated, injection molding enables mass production of hundreds, thousands or millions of identical plastic parts in a short timeframe.


  • Surface Finishes

    Multiple surface finish options like gloss, matte, soft-touch and textured can be achieved straight from the molded part with no secondary processing.

  • Q

    What is plastic injection molding?

    A

    Plastic injection molding is a manufacturing process for producing plastic parts in high volumes. Granulated polymer is melted and injected under pressure into a mold, where it cools and hardens into the final part shape.


  • Q

    What is an advantage of injection molding?

    A

    Injection molding enables high production output, part consistency, complex geometries, tight tolerances, material versatility, and lower costs for large production runs compared to other manufacturing methods.


  • Q

    What's the process for injection mold making?

    A

    Injection molds are CNC machined from tool steel to high precision based on a CAD model. The two-plate mold is designed with cooling channels and precision-ground surfaces to repeatedly produce complex plastic parts.


  • Q

    What are the typical tolerances for injection molded parts?

    A

    Injection molded parts can routinely hold dimensional tolerances of ±0.005 inches and as tight as ±0.002 inches due to the consistency and repeatability of the automated injection molding process.
