Two-color molding and overmolding
1. Advantages of two-color molding:
Two-shot molding, also known as 2-shot molding, twin-shot molding, co-injection molding, or multi-shot injection molding, produces parts with two different colors and/or materials in one operation.
The two-color mold can combine two resins with different characteristics and colors into a single two-color product, which reduces the assembly and post-processing of the molded product, saves the cost of melting and printing, increases the aesthetic effect, and improves the grade and additional of the final product Value, not only anti-skid increases friction, but also flexible resin material makes it more ergonomic and feels better. Two-color injection molding products have high quality stability, are easy to control product deformation, shorten the molding cycle, increase production, the scrap rate is 7% lower than overmolding, and the product manufacturing cost is reduced by 20%-30% lower than the latter.
Production process characteristics of two-color injection molding products
1. Two-color injection molding machine is composed of two sets of plastic injection devices with the same structure and specifications. The nozzle needs to have a special structure according to the production method, or be equipped with two sets of injection molds with the same structure that can be rotated and replaced. During plasticizing, the process parameters such as melt temperature, injection pressure and injection volume in the two sets of plasticizing devices are required to be the same, so the fluctuation of process parameters in the two sets of devices should be minimized.
2. Compared with ordinary injection molding products, the melt temperature and injection pressure parameters of two-color injection molding products are higher during the injection process. The main reason is that the flow channel in the two-color mold is longer, the structure is more complex, and the melt flow resistance is higher. big.
3. For two-color injection molding products, it is best to choose raw materials with good thermal stability and low melt viscosity to avoid decomposition due to high melt temperature and long residence time in the flow channel. The most widely used plastics are PC, PS, ABS and so on.
4. In the injection molding process of two-color plastic products, in order to make the melts of two different colors weld well in the mold and ensure the quality of the molded products, higher melt temperature, mold temperature, injection pressure and injection speed should be adopted. was adopted.
In addition, two-color molding: not only anti-skid increases friction, but also flexible resin material makes it more ergonomic and feels better. Double-color injection molding products have high quality stability, easy to control product deformation, shorten molding cycle, and increase output
