Our Manufacturing Processes

We specialize in plastic injection molding, which involves the injection of melted plastic into a mold made of steel. The mold itself has cavities that will form the parts; once injected, the molten plastic fills the cavities and the rest of the mold. Once cooled, the parts are ejected by pins.

Plastic Injection Molding

Plastic injection molding is a manufacturing process that creates plastic parts by injecting molten plastic into a mold. The process is often used to make plastic parts in large quantities.

How it works:
  1. Melt the plastic
    A screw pushes plastic pellets through a barrel, creating friction that melts the plastic.
  2. Fill the mold
    The molten plastic is forced into the mold through a plunger at the front of the screw.
  3. Cool and solidify
    The plastic cools and solidifies in the mold, taking the shape of the part.
  4. Eject the part

The mold opens and ejector pins push the part out.

Why it's used:
  • Low cost per part
    Injection molding is economical for mass production because the cost per part drops significantly once production begins.
  • Versatile
    Injection molding can be used to create a wide variety of parts, from small, intricate parts to large automotive parts.
  • High dimensional accuracy
    Injection molding can produce parts with high dimensional accuracy, even for complex designs.
What it's used for:
  • Automotive
    Injection molding is used to make car parts.
  • Medical devices
    Injection molding is used to make parts for surgical equipment.
  • Consumer goods
    Injection molding is used to make toothbrushes, kitchen appliance housings, and more.
