What are the major standards for high-quality injection molds? Let's take a look together.

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 manufacture 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 precision 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 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 ground.

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, a lot of friction will be formed on the surface of the entire mold. Therefore, it is necessary to select wear-resistant mold steel to ensure the large batch The quality of the products has always remained stable during the injection molding production process.
