Advantages of Two-color Injection Molding

Compared with ordinary injection molding, two-color injection molding has the following advantages:

  1. The 2K molding main raw materials can use low viscosity material to reduce the injection pressure.
  2. The 2K molding main raw materials can use recycled recycled plastic, both environmental friendly and economy.
  3. Meet the special requirements of some products, make plastic parts more beautiful and colorful. For example, soft plastic is used for the surface material of the thick  product, and hard plastic or foamed plastic is used for the main body to reduce the weight.
  4. lighter or cheaper plastics can be used in unimportant parts of over-molding parts to reduce product cost.
  5. The expensive and special performance of plastic material could be used on the important and special area , such as electromagnetic interference prevention, high conductivity and other plastics
  6. Proper combination of surface material and core material can reduce residual stress of 2K plastic parts, increase mechanical strength or optimize surface performance of products.
  7. Products surface like marble texture can be obtained.
