Our Services

Injection Molding

  • Thermoplastic Injection Molding

  • RapidDirect enables the design and production of tools, dies, and molds for rapid tooling, prototyping and mass production.

  • Mold Making

    Injection molding transforms 3D models into high-quality molds rapidly. We offer mold making processes suitable for both prototyping and mass production runs. 

  • Overmolding

    By injecting a thermoplastic elastomer or silicone rubber material directly onto a rigid plastic substrate, overmolding produces high-quality, multi-material parts. 

  • Insert Molding

    A metal pre-formed part is loaded into a mold and subsequently overmolded with plastic to produce the final part.
