    Plastic Products Design

    You can simply provide us with a 3D or a 2D drawing with the tolerance requirements, and our team will design them by using various software like SolidWorks, AutoCad, Mold Flow MPI and enhance it for manufacturability.

    3D printing & prototype

    Plastic Injection Mold Design

    Our injection mold designers have more than 10 years of experience in designing electronic pieces and precise molds. Materials, ejection mechanisms and other factors are considered when we put forward a perfect mold tool design.

    3D Prototype

    The 3D prototype is based on the finalized design by the client. Accurate proptotypind sets a precedent for mass production. Only precision methods make the 3D prototype suitable for injection molding later.

    mold tooling making

    Making Mold Tooling

    During the mold tooling process, we take the help of advanced plastic injection tools. CNC machining, EDM, and drilling as well as milling machines are in the facilities. The manufacturing workshop has experts for operating these machines.
