In some large processing plants, there are more and more places where die-casting aluminum molds are used. When installing, it is necessary to know the processing steps of die-casting aluminum molds. After knowing these steps, it can be installed more quickly.
The four basic processes in the die-casting aluminum industry are annealing, normalizing, quenching and tempering. However, in the process of die casting, the relationship between quenching and tempering is very close, and these two processes are indispensable. Here we will introduce you to these four process annealing: of course, the die-casting aluminum mold is heated. When the temperature is added to the proper temperature, you need to cool it according to the different materials selected to make it internal. Balance.
Normalizing: This process is to cool the product to a suitable temperature and then to cool it in air to improve the cutting function of the material. Quenching is to heat the workpiece and then quench it in water or by other inorganic salt solutions. Rapid cooling in the medium causes the mold to harden and also makes the steel brittle. Of course, if you want to reduce the fragility of the steel, you can place the steel after the liquid fire at a temperature below 650 °C above normal temperature for a long time, then cool, and the process is tempered. .
