Injection mold is a tool for producing plastic products. The processing method of injection molding is used to produce some products with complex shapes 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?
First of all, in the process of injection molding to produce products, the temperature in the injection mold is generally relatively high. 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. Therefore, in the production process of injection molding, the corresponding injection mold cavity surface roughness is required to be relatively small, so that plastic products that meet the standards can be injection molded, 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 choose wear-resistant mold steel to ensure large quantities The quality of the product has always remained stable during the injection molding production process.
