The exhaust system for ensuring product quality plays a vital role in shaping: A, the use of exhaust ducts, exhaust ducts, generally located in the depth of the cavity is filled with the last part of precision plastic mold, exhaust ducts because of plastic varies Shenzhen plastic mold, basically no plastic burr maximum gap allowed to determine, such as ABS 0.04 to 0.02mm or less match steel marl 0.02. B utilizing core inserts Putters with the gap or dedicated exhaust vent plugs; C sometimes cause a vacuum in order to prevent distortion products at the top out, will set up gas marketing; D products and sometimes in order to prevent a vacuum suction mold, designed anti-vacuum components. Plasticizers Plasticizers can increase the plasticity and softness of plastic, to reduce the brittleness, so that the plastic processibility. 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. Such as the production of PVC, adding more if you can get a soft PVC plasticizers, if not add plasticizers or less (the amount of <10%), plastic injection mold, you have a hard poly vinyl chloride plastic. Stabilizers to prevent the effect of the synthetic resin by heat and light during processing and use during decomposition and destruction, long life, to add stabilizers 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.
