Due to defects such as oxidized inclusions or looseness in the die casting, the compactness of the casting is reduced. For die castings with air tightness requirements, these micro-gaps can be filled by infiltration treatment. So what are the benefits of infiltration treatment of aluminum alloy die castings?
1. Improve efficiency and output
1. The foam model used for the impregnation of aluminum alloy die castings is mechanical foam. While ensuring the quality of the model, the production speed is also quite rapid.
2. The impregnation process of aluminum alloy die-casting parts simplifies the cumbersome steps of traditional processes, such as modeling the lower core, which is not only laborious and inefficient.
3. The aluminum alloy die-casting parts are impregnated into one box with multiple injections, and multiple boxes can be poured at the same time until the metal solution is used up.
Second, cost savings
1. The mold used for the impregnation of aluminum alloy die castings can be used for life, with almost no loss, reducing or eliminating the cost of the mold.
2. The infiltration of aluminum alloy die-casting parts abandons the traditional core-forming process, which saves labor and reduces manufacturing costs.
3. The infiltration of aluminum alloy die-casting parts has gradually developed from a casting industry that uses many male workers to many female workers, and the labor force has been greatly reduced in various links, and the cost has been reduced in disguise from the wages of workers.
4. Sand for impregnation of aluminum alloy die castings can be recycled, with a loss of 2%-5%.
Infiltration treatment is to immerse the die-casting part in the impregnating liquid filled with infiltration and filling, so that the infiltrating liquid penetrates into the loose parts inside the die-casting part, thereby improving the airtight performance of the die-casting part.
