Aluminum Die Casting Auto Parts must be heat treated during factory processing, and there are also many precautions during heat treatment.
The first is to control its heating temperature to the right degree, and the second is to ensure its heat preservation time and not let it cool down too fast.
When dealing with this kind of Aluminum Die Casting Auto Parts, we must also pay attention to maintaining its dimensional stability, so as to have a good effect.

Annealing heats Aluminum Die Casting Auto Parts to a higher temperature, generally about 300°C. After holding for a certain period of time, the process of cooling to room temperature with the furnace is called annealing. During the annealing process, the solid solution decomposes and the second phase particles gather, which can eliminate the internal stress of the casting, stabilize the size of the casting, reduce deformation, and increase the plasticity of the casting.
The solution treatment heats the casting to the highest possible temperature, close to the melting point of the eutectic, keeps it at this temperature for a long enough time, and then cools it quickly, so that the strengthening components are dissolved to the limit, and this high temperature state is fixed and preserved At room temperature, this process is called solution treatment. Solution treatment can increase the strength and plasticity of the casting and improve the corrosion resistance of the alloy.
Solution treatment temperature, the higher the temperature, the faster the strengthening element dissolves, and the better the strengthening effect. Generally, the upper limit of the heating temperature is lower than the overburning temperature of the alloy, and the lower limit of the heating temperature should make the strengthening components as much as possible dissolve In solid solution.
In order to obtain the solid solution strengthening effect without the inconvenience of over-burning the alloy, sometimes the method of graded heating is used, that is, the temperature is kept at the low melting point eutectic temperature, so that the low melting point eutectic does not exist after the components are diffused and dissolved. Raise it to a higher temperature for heat preservation and quenching. During solution treatment, it should be noted that the heating rate should not be too fast, so as to prevent Aluminum Die Casting Auto Parts from deforming and locally aggregated low-melting structure melting and causing over-burning.
