Two-color Injection Molding
Feb 18, 2023
It refers to the molding method of injecting two different colored plastics into the same mold. It can make the plastic appear two different colors, and can make the plastic parts present a regular pattern or irregular moiré pattern, so as to improve the usability and aesthetics of the plastic parts.
Technical Features:
1. The core material can use low-viscosity materials to reduce the injection pressure.
2. From the consideration of environmental protection, the core material can use recycled secondary material.
3. According to different use characteristics, for example, soft materials are used for the skin layer of thick products, hard materials are used for core materials, or foamed plastics can be used for core materials to reduce weight.
4. Lower quality core materials can be used to reduce costs.
5. The skin material or core material can be expensive and have special surface properties, such as anti-electromagnetic interference, high electrical conductivity and other materials to increase product performance.
6. Appropriate combination of skin material and core material can reduce the residual stress of molded products, increase mechanical strength or product surface properties.
