Injection Molding Process

  • Mold Design & Manufacturing

    Molds are designed from drawings, steel chosen by production, and precision machined for accuracy.

    01
  • Material Pre-Treatment

    Plastic materials are dried to remove moisture, with color or additives added to meet requirements.

    02
  • Injection Molding

    The molten plastic is injected under pressure, then packed and cooled to control shrinkage and ensure quality.

    03
  • Demolding

    After sufficient cooling, the mold opens and molded parts are ejected either manually or automatically. Parts are handled carefully to prevent deformation or surface damage.

    04
  • Post-Processing

    Excess material is removed, parts are finished as needed, then inspected and packaged.
