What is Plastic Injection?

Plastic injection molding is the most widely-used manufacturing technique for the production of mass units of plastic parts that serve industrial and commercial purposes. Plastic injection molding also has the highest range of materials, color, and configuration when put side-by-side with processes like CNC machining or Additive manufacturing

Plastic Injection Molding with fast profuction speed and high efficiency, can cover many varieties of designs and colors. The shape can be from simple to complex, so as the size(from large to small). Injection molding is suitable for mass production, complex shape products. more options for materials and treatment.

There are mainly six stages: mold closing, glue injection, pressure maintaining, cooling, mold opening and product removal.

    形状 Created with Sketch.
    Moldmaker's choice of finish. Typically SPI B-2, depending on geometry and drafts. Interior, non-cosmetic faces, are typically as-machined.
  • SPI Finishes
    Created with Sketch.
    形状 Created with Sketch.
    Range of Society of Plastics Industry (SPI) finishes from Grade 3 diamond / high polish to 320 stone low polish. Finishes include: SPI A-1, SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3
  • MoldTech Finishes (Mold Texturing)

    Holy has the ability to assemble and label injection molded parts. Discuss your needs with your salesperson.
  • Rapid Prototyping: Low-cost tooling allows for rapid injection molding to be produced in as fast as 10 working days at affordable prices.

    Production Parts: Injection molding can be the ideal process for low-volume production molding of 250 units to mass production molding of over 1,000,000 units. Plastic injection parts will generally perform better than the same part CNC machined or 3D printed using the same material. Careful selection of the resins allow for a wide range of properties and solvent compatibility. Molds are CNC machined to high precision, high tolerances and are able to produce thousands of identical parts with very small and intricate details.
