Two-color injection molding products are not only a simple combination of two or more colors of plastics, but also have higher requirements on injection molding machines in terms of product accuracy, beautiful appearance, better integration of different color plastics, and product molding cycles. Monochrome injection products are relatively simple.
Two-color injection molding products, for products with different plastics on the inner and outer layers, can be replaced by secondary processing to one-time molding. Monochrome injection molding products do not have this function.
Two-color injection molding products can give old products (molds) new life due to different color combinations. The core material can use low viscosity raw materials to reduce the injection pressure.
For two-color injection molding products, the corresponding two-color injection molding machine can also be used to produce single-color products. The core material can use recycled waste materials or low-quality raw materials to reduce costs. The skin material can be made of high-quality materials with special surface properties or anti-electromagnetic interference to increase product performance. Proper combination of skin material and core material can reduce residual stress and increase product strength.
The advantages of the two-color molding die are as follows:
1. The product has high precision and stable quality.
2. Good structural strength and durability.
3. The fit gap is small and the appearance is good.
4. Greatly reduce the cost.
Two-color mold: two plastic materials are injected on the same injection molding machine and molded in two times, but the product is only molded once. In general, this molding process is also called double injection molding, usually completed by a set of molds, and requires a special two-color injection molding machine. Two-color molds are becoming more and more popular on the market. This process can make the product look more beautiful, and it is easy to change the color without spraying, but the cost is high and the technical requirements are high.
