Share the secret of reasonable control of injection mold processing color.
1. To reduce the influence of the barrel temperature on the color difference, it is often encountered that a heating ring is damaged and invalid, or the heating control is out of control, and the barrel temperature changes dramatically and then produces color difference.
2. To eliminate the influence of injection molding machine and injection mold elements, it is necessary to select an injection molding machine with appropriate volume of injection molding products. If there are questions about the dead angle of materials in the injection molding machine, it is the best to replace the equipment. For the color difference caused by mold pouring system and exhaust slot, it can be handled by corresponding mold repair. It is necessary to deal with the problems of injection molding machines and molds before production can be organized to reduce the complexity of the problems.
3. The key to thoroughly deal with color difference is to eliminate the influence of resin and color masterbatch on raw materials. Therefore, especially in the production of light colored finished products, the significant impact of different thermal stability of material resins on the color fluctuation of finished products cannot be ignored. Whereas most injection mold manufacturers do not produce plastic masterbatch or color masterbatch. In this way, attention can be focused on production management and raw material inspection.
