• • •

Co-molding, also known as Overmould or Insert-Molding, enable the use of two or more different materials in one part, thus improving the quality and performance of the product.

Advantages of Co-molding

  • Simplifying assembly and Lower assembly cost
  • Improving sealing quality between components
  • Increase rigidity and strength of the part
  • Achieve device functionality
  • Design flexibility and Optimise space
