Special Process for Die Casting Processing.custom steel plate fabrication

　　1. Annealing. Annealing is the process of heating aluminum alloy castings to a higher temperature, usually around 300 ℃, holding them for a certain period of time, and then cooling them to room temperature in the furnace. During annealing, the solid solution will differentiate and the phase particles will show a trend of aggregation. At this time, the internal stress of the casting can be removed to prevent deformation of the casting. 2. Solid solution. The effect of solid solution is generally related to three aspects: solution treatment temperature, solution treatment insulation time, and cooling speed. The higher the temperature of solid solution treatment, the faster the dissolution rate and the better the effect. 3. Timeliness. Aging treatment is the process of supersaturated solid solution differentiation, which can help the lattice of the alloy matrix recover to a relatively stable state. Its main purpose is to improve the mechanical properties of the alloy and enhance its corrosion resistance.
