Suzhou double color injection molding factory: Suzhou double color injection molding products production process characteristics
1. The two-color injection molding machine is composed of two sets of plasticizing injection molding devices with exactly the same structure and specifications. The nozzle has a special structure according to the production mode, or is equipped with two sets of molds with exactly the same structure that can rotate and transpose. When plasticizing injection molding, it is required that the melt temperature, injection pressure, injection melt amount and other process parameters in the two sets of plasticizing injection molding devices are the same, and the fluctuation difference of process parameters in the two sets of devices should be minimized.
2. Two-color injection molding plastic products and ordinary injection molding plastic products, the melt temperature and injection pressure during injection molding should use higher parameter values, the main reason is that the two-color injection molding mold runner is relatively long, the structure is more complex, injection melt flow resistance is larger.
3. Two-color injection molding plastic products should use raw materials with good thermal stability and low melt viscosity to avoid decomposition due to high melt temperature and long residence time in the runner. The most widely used plastics are polyolefin resins, polystyrene and ABS materials.
4. Two-color plastic products in injection molding, in order to make the two different colors of the melt in the mold can be well welded, to ensure the quality of injection molding products, should be used higher melt temperature, higher mold temperature, higher injection pressure and injection rate.Key words:- 苏州双色注塑
