Two-Color Molding

Two Shot and Two Color molding is a Denver Plastics specialty

Two-Color Molding may also be referred to as: 2-Shot molding, Bi-injection molding, Co-injection Molding, or Multi-Shot Injection Molding

This technology produces a part with two different colors and/or materials in a single operation. The machine has two injection units: one vertical and one horizontal. By using a rotating mold, the machine automatically produces a substrate of one resin or color and overmolds the part with the second resin or color.

Denver Plastics provides two-shot two-color molding for a variety of industries. Typically, two-shot two-color molding is used for soft-touch over-molding grips in power tools, outdoor equipment, medical equipment, electrical equipment, consumer products, and automotive components. This process reduces part costs by eliminating labor, improving quality, and eliminating post-molding steps such as sonic welding, assembly, snap fits or fasteners. The cost advantages become obvious, especially when applied to high volume parts.

Advantages over alternative methods:

  • Insert molding and complex secondary operations are eliminated.
  • Painting (which can rub off) is eliminated.
  • Strong substrates can be molded with soft-feel materials on the outside. For more information, please see our Elastomeric Soft-Touch Over-molding page.
  • Two-color applications can enhance appearance.For more information, please see our Elastomeric Soft-Touch Over-molding page.
  • Cores can be made of recycled material
  • Moldings with high surface quality
