After the mixing of PP raw material and color masterbatch, the mixture is extracted for fusion injection molding. The uniformity of the mixture is the key control point.
[0003] Currently, the injection molding material is mixed by PP and color masterbatch in a certain proportion, and the incomplete mixing and uneven mixing can lead to poor consistency of the surface color of the tank and cover, affecting the appearance. If PP and color masterbatch are placed for too long, some water will remain on the surface, and a small amount of metallic iron impurities will be contained in the incoming particles. Water can cause white spots on the injection molding tank cover product, and iron impurities can react with the dilute sulfuric acid inside the battery to dissolve, causing tank leakage. Therefore, it is necessary to remove water and iron impurities.
