The pretreatment of the molding materials before the production of the plastic barrel manufacturer includes analysis and inspection of the quality of the molding materials and preheating and drying. ①Analyze and check the quality of the raw materials. According to the requirements of the injection molding process characteristics of the raw materials, check the moisture content, color, fineness and uniformity of the raw materials, whether there are impurities, and test their heat stable 50-liter plastic barrels
The pretreatment of the molding materials before the production of the plastic barrel manufacturer includes analysis and inspection of the quality of the molding materials and preheating and drying. ①Analyze and inspect the quality of the raw materials. According to the requirements of the injection molding process characteristics of the raw materials, check the moisture content, color, fineness and uniformity of the raw materials, whether there are impurities, and test its thermal stability, fluidity and shrinkage. If problems occur in the inspection, timely measures should be taken to solve them. ②Preheating and drying: For highly hygroscopic plastics such as nylon, polycarbonate, ABS, etc., before molding, sufficient preheating and drying should be carried out according to the moisture requirements allowed by the molding process to remove excessive moisture and volatiles in the material to prevent After molding, the plastic parts have defects such as bubbles and silver wire, and can also avoid water degradation during injection.

In the injection molding production, in order to make the plastic parts easily released from the mold, some mold cavities or mold cores need to be coated with a mold release agent. Common mold release agents include zinc stearate and liquid paraffin And silicone oil. For soft products or transparent products containing rubber, it is not appropriate to use a release agent, otherwise it will affect the transparency of the product.
