Shuangcheng Hardware knows that many die-casting companies know that unreasonable use of die-casting dies will cause many problems. Today, Shuangcheng Hardware will give you a detailed explanation abouthardware die-casting I. Molten metal liquid enters the mold cavity at high pressure and speed, which will produce severe impact and corrosion on the surface of mold forming parts, causing corrosion and wear on the surface of mold steel. The pressure will cause the offset and bending of the mold core II. During the filling process of the metal die casting mold, the metal liquid, impurities and slag will have complex chemical effects on the mold surface, thus accelerating the surface corrosion and cracks III.The metal die castingdie is produced at a very high working temperature, so the thermal stress produced is the main reason for the surface cracks and even the overall cracks of the die forming parts, which will lead to the scrapping of the die. In the production process of eachmetal die castingpiece, in addition to being scoured by the high speed and high pressure of the metal liquid, the cavity surface also absorbs the heat released during the solidification of the metal materials, resulting in Thermal conversion. Due to the limitation of heat conduction, the cavity surface can reach a very high temperature first and then expand, but the temperature of the inner layer mold needs to be relatively low, and the expansion force will be relatively small, so the surface will generate compressive stressmetal die castingafter opening the mold, the cavity surface will contact with the air, be cooled by compressed air and paint, and generate tensile stress. The production time increases with the increase of production time IV. There will be air holes in the metal die casting. The reason for the metal die casting is that the air is mixed in the molten soup, the dissolution is improper, and the release agent cannot be used correctly Shuangcheng Hardware believes that the above will give you a better understanding ofhardware die-casting.
