A plastic mold design knowledge based on dimensional accuracy associated with design size is correct. Specifically plastic products throughout the product to be outside and functionality to determine its quality and specific dimensions which are based on: the appearance of a higher quality requirements, dimensional accuracy requires a lower plastic products. Such as toys; functional plastic products, strict size requirements; appearance and dimensions are very strict requirements for plastic products. Plastic mold processing such as a camera, stripping slope not reasonable. Drafts of stripping and directly related to the quality of plastic products, which is related to the injection process Shenzhen plastic mold, injection can be smoothly carried out: stripping slope enough; gradient want and plastic molding parting or parting surface adaptation; whether it will affect the accuracy of the appearance and the thickness dimension; whether it will affect the strength of certain parts of plastic products. Plasticizers Plasticizers increase the plasticity and flexibility of plastics, reduce the brittleness of plastic molds, plastic molding process is easy. Plasticizers are generally miscible with the resin, non-toxic, odorless, light, heat-stable 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. Plastic mold structure, Guangdong plastic mold, mold Ltd.
