When heat treating aluminum castings, their melting point is very low, making them prone to overheating. The temperature deviation after heating is relatively small. Aluminum castings have very high requirements for the accuracy of temperature measurement instruments. If the insulation deviation after heating is relatively large, the purpose of strengthening cannot be achieved. Therefore, it can be seen that controlling the heating temperature of hot aluminum castings is the key in the entire process. After numerous experiments, it has been confirmed that there is a connection between the temperature generated during manual operation and the duration. If the aging temperature is relatively high, the holding time will be shortened, while if the aging temperature is relatively low, the holding time will be extended to a certain extent. If handled in this way, it will have a large degree of dispersion for large-scale production. If the quality of the final product is not well controlled, the application of the second method can increase the pass rate of the product and also ensure the process quality of the product.
