Color injection should pay attention to: soft partial package of hardware products, these are the most frequent color injection mold problem, you need to pay attention to the material and the adhesive material between the junction between the two mold processing materials (general embossed lines of the phenomenon will have to do a lot of problems or seal cavity) as well as the thickness of the material thickness, etc.! If on the one hand not considered good will have trouble! Abrasives are the same as the male mold different mother die so the design must consider many color injection molding, for example: Do not consider doing slant on the second mold public mode, bit line position or pillow or something. Injection molding technology in the field of automotive plastic parts 1, such as car bumpers, instrument panels and other materials commonly used resin modified ABS modified PP and other modified resins, resin materials have different moisture and water to meet the molding parts content requirements (General requirements 0.2%) Shenzhen color injection molding, resin raw materials before entering the pre-plastic injection molding machine screw metering, go through the hot air drying or dehumidification drying process. Modified PP (PP + EPDM) absorbent resin is small, typically using a hot air dryer under the conditions of 80-100 ℃ 2-3h can. Modified ABS (PC + ABS) are hygroscopic, in mixed doubles before drying color injection molding machine, the application of desiccant dehumidification drying machine. We in the design of complex automotive plastic parts molding system fully consider the use of desiccant system functions. 2, the domestic automotive plastic parts is substantially free of glass fiber reinforced plastic products. And containing chopped glass fiber reinforced resin, compared to none of glass fiber reinforced plastic parts and the materials and structure of the screw injection molding machines are quite different. Injection molding machine in the design of alloy screw barrel and a special heat treatment process to ensure that its corrosion resistance and strength. 3, due to the different auto parts and conventional products, it is very complicated cavity surface, discontinuity, etc., stress uneven distribution of key consideration in the design of its products for the processing capacity to adapt.
