Four criteria for the high quality of injection molds




Injection mold is a tool for producing plastic products. Through the processing method of injection molding, some products with complex shapes are produced in batches. During the injection molding production process, the quality of the injection mold determines the quality of the final product, especially for Some precision electronic products have particularly high requirements for injection molds. We need to comprehensively measure when choosing injection molds, so how to judge the quality of injection molds?




4 major standards for the quality of injection molds




First of all, in the process of injection molding to produce products, the temperature in the injection mold is generally higher. Therefore, the steel used by the injection mold factory to make the injection mold must be high temperature tempered mold steel, so that the overall design is good even in a high temperature environment The size of the mold will not be affected, thereby ensuring the accuracy of the mold as a whole.




Secondly, in the process of injection molding, the raw materials of plastic products such as resin and various additives will corrode the surface of the injection mold, thereby affecting the overall precision of the injection mold. Therefore, corrosion-resistant steel must be used in the selection of mold steel. Kind.




Plastic products generally have relatively high requirements for surface gloss, so in the production process of injection molding, the corresponding injection mold cavity surface roughness is required to be relatively small, so that injection molding can produce plastic products that meet the standards, so it must be selected For mold steel that does not contain impurities and pores, after the injection mold is manufactured, the surface of the mold cavity must be polished and grinded.




Finally, in the process of using injection molds to produce plastic products, due to the high-speed flow of plastic raw materials in the cavity of the injection mold, it will form a lot of friction on the surface of the entire mold. Therefore, it is necessary to select wear-resistant mold steel to ensure the mass production During the injection molding production process, the product quality has always remained stable.
