The production of injection molding products, need to use injection molding molds, generally under normal circumstances, plastic products produced by this injection molding method, the surface has a better gloss and color, but sometimes it is inevitable that there will be some shortcomings, in addition to the material problems of the plastic itself, colorants and the gloss of the mold surface, what are the reasons for injection molding processing to cause such an impact?
Generally speaking, plastics have large crystallinity, small polarity or non-polarity, and low surface energy, which will affect the adhesion of the coating. Since plastic is a non-conductive insulator, it cannot be directly coated on the surface of the plastic according to the electroplating process regulations. Therefore, before the surface treatment, the necessary pretreatment should be carried out to improve the adhesion of the coating and provide a conductive bottom layer with good adhesion to the coating.
there are more and more plastic products processing around us, plastic products processing has many advantages, such as small quality, exquisite appearance, not easy to be rotted, good impact resistance, etc., so plastic products are now very many fields and industries beloved, but also in our daily life has become a commodity that can often be seen, if you look around, there is no doubt that plastic products will appear in everyone's field of vision, it can be said that plastic has long become a raw material that is inevitable in everyone's daily life. However, many people do not know that the production of plastic products is actually asset-risky.
In the case of injection molding processing, it will undoubtedly be applied to injection molding machine equipment, it is a process that cannot be missing in the entire production process, and its necessity cannot be ignored. However, in the case of the application of injection molding machine for production and processing, we must pay attention to the difficulty of the temperature rise of the equipment too quickly, which is likely to lead to great shortcomings.
What are the problems that need to be paid attention to in injection mold processing when designing flange shaping molds?
Plastic products processing manufacturers in many plastic parts, pay attention to polyvinyl chloride, styrene, polyethyl acetate and acrylate and other plastics, the remaining small amount of monomer will produce an unpleasant odor, the use of monomer residual resin can remove those odors.
