What is the effect of temperature on the performance of aluminum alloy precision die castings?
       Aluminum alloy precision die castings need to be treated by low temperature aging and cannot be strengthened by heat treatment. Because in the process of aluminum alloy precision die casting, the gas in the die casting cavity will be stored in it for a long time, and there is no chance to overflow. These gases begin to expand during the heat treatment process, causing the casting to deform and bulge. Next, the aluminum alloy precision die casting manufacturer-Suzhou Yiguan Hardware will tell you what effect the temperature has on the performance of aluminum alloy precision die castings?
       The cooling effect of the die-casting mold can make the elements in the aluminum alloy precision die-casting parts saturated, which is the basis for the heat treatment of aluminum alloys. The cooling effect of the die-casting mold is used to replace the solution treatment of the aluminum alloy, so that the deformation and bulging of the casting can be avoided, and the purpose of strengthening the aluminum alloy can also be achieved.

Aluminum alloy precision die casting

       Through the test and analysis of high-strength die-casting alloys, aluminum alloy precision die-casting manufacturers understand the influence of low-temperature aging on the performance of aluminum alloy die-casting. Aging technology plays a great role in the enhanced production of aluminum alloys. The understanding of aluminum alloy die-casting aging technology is also to closely combine the phenomenon of current engineering demand for aluminum alloys.
       It is revealed that heat treatment can shorten the aging time of aluminum alloys and affect the properties of aluminum alloys. Experiments show that our team has carried out a better analysis of the effect of low temperature aging on aluminum alloy precision die castings, revealing the aluminum alloy strengthening aging process. While the mechanical properties are improved, the hardness and strength of the aluminum alloy are strengthened, the aging time can be shortened, and the cost can be reduced, and the technical and economic benefits of aging are significant.
       The cooling rate has a significant impact on the performance of aluminum alloy precision die castings. Only by correctly grasping the cooling rate of aluminum alloy precision die castings can the aluminum alloy precision die castings achieve the required quality in the as-cast state and improve the quality of the castings.
       The cooling rate will definitely affect the quality of aluminum alloy precision die castings. The cooling of aluminum alloy precision die castings is a process of thermal expansion and cold contraction. If one part of the aluminum alloy precision die casting shrinks quickly, another part shrinks slowly. , Aluminum alloy precision die castings are subject to internal stress, which will lead to casting deformation and casting defects.
       In addition, the speed of cooling will affect the internal crystal structure of aluminum alloy die castings. The faster the cooling speed, the lower the actual crystallization temperature and the greater the degree of subcooling. On the contrary, the slower the cooling rate, the smaller the degree of subcooling, and the actual crystallization temperature is closer to the theoretical crystallization temperature. When the cooling rate is large, the grains of the casting are finer.
