Five: the cooling system to meet the injection molding process for mold temperature requirements to ensure a variety of products, cooling stereotypes. Waterway should be in parallel fashion. Six: exhaust system ensures the plastic melt in the mold filling process gas is discharged to allow the plastic melt smoothly filled cavity to prevent air bubbles plastic products, mold design, shrinking charred other defects. Plasticizers Plasticizers increase the plasticity and flexibility of plastic, reducing brittleness precision plastic mold manufacturers, plastic molding process is easy. Plasticizers are generally miscible with the resin, non-toxic, odorless plastic mold, optical, thermal stability of the high-boiling organic compounds, the most commonly used phthalates. E.g., the production of PVC, if more plasticizer can be added to give a soft PVC, or less if not add plasticizers (amount <10%), then the obtained rigid PVC . Stabilizer to prevent the effects of synthetic resin by light and heat in the processing and use of decomposition and destruction, to extend the life of Shenzhen, plastic mold, to join a stabilizer in plastics. Commonly used are stearates, such as epoxy resin. Plastic colorants colorants can have a variety of bright, beautiful colors. Common organic dyes and inorganic pigments as colorants. Lubricants Lubricants role is to prevent non-stick plastic molding on the metal mold, while allowing the plastic surface is smooth and beautiful. Commonly used lubricants are stearic acid and calcium magnesium salts and the like. In addition to the above additives, the plastic may be added a flame retardant, foaming agent and antistatic agents.
