At present, two-color injection molding has been widely used in electronic products, electric tools and other injection molding industries. In the medical products and home improvement industries, we are now producing and producing two-color molds. The research and development of two-color injection molding machines and raw materials has also made great progress, so what are the characteristics of two-color injection molds?
1. Low-viscosity materials are suitable for reducing the injection pressure of key materials.
2. From the perspective of environmental protection, key materials can be recycled as secondary materials.
3. According to different application characteristics, for example, soft materials should be used for thick finished cortex materials, and hard materials or foam plastics should be used for key materials to reduce net weight.
4. Low-quality key materials are suitable for cost reduction.
5. Cortical materials or key materials are expensive and have special surface characteristics, such as avoiding interference signals and high conductivity materials that improve product performance.
6. Appropriate skin materials and key materials can reduce the residual stress of the molded product and improve the fracture toughness or surface characteristics of the product.
