Hardware die casting forming temperature note?

Time:2021-04-14 10:15:12Click:

       I believe many people will not feel unfamiliar with hardware die casting, because as an effective metal casting process, it has a relatively wide range of applications in many related industries. Die casting mainly refers to the application of a high pressure to the molten metal using the cavity of the mold, so that it becomes what we want.
       Die casting is a kind of pressure casting part. It uses a pressure casting mechanical die casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the inlet of the die casting machine and pass it through the die casting machine. Die-casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size restricted by the mold, such parts are usually called die-casting parts. So what do you pay attention to about the forming temperature of hardware die castings?
       In the process of die-casting, if the temperature is controlled too low, the internal structure of the entire casting will generally become looser. In terms of air exhaust, the difficulty will also increase. Therefore, for the entire forming, it is also relatively difficult.
      In addition, if the temperature is too high, it is also undesirable, because it will make the internal structure of the die-cast metal too tight, which will increase the difficulty of unloading during the sticking process. At the same time, too high temperature will cause the phantom itself to expand, which will affect the accuracy.
       Therefore, only by controlling the temperature within a reasonable range during the operation of the die-casting plant, can the success rate of the entire die-casting process become higher. It mainly refers to three aspects: the melting temperature of the material, the temperature of the mold during injection, and the temperature of the melt.
