Double Injection Mold

Double Injection Mold

Double injection molding is a process of producing parts with two different polymers or two different colors during single operation. The process starts with injecting the melt into primary cavity. Then the cavity plate rotates by 180 degree or the primary molding is moved to the secondary cavity. Finally the second color or a different polymer is injected into secondary cavity to fill the space between primary molding and secondary cavity.

Welson Mold can help you make the double injection molding and mold. We start from the parts design analysis, tooling design, tooling manufacturing through the whole project management, to parts injection and delivery.

Double Injection Molding optimizes co-polymerization of hard and soft materials to create powerful molecular bond. The result is a single part with production and feature advantages. It can be used for a variety of product designs across all industries. It also allows for molding using clear plastics, colored graphics and stylish finishes which improving your product functionality and marketplace value.

Double Injection advantages include:

  • Lower unit cost
  • Improved part integrity
  • Multi-material efficiency
