What is the reason for the particle foreign matter in aluminum alloy die castings?
In order to prevent the occurrence of particles, relevant measures must be adopted to improve the casting quality of the company.
1. The effect of particles on the casting is that the strength of the casting becomes worse and the deformation resistance is relatively weakened. It also has a great influence on its surface treatment, especially in the time of pretreatment, it is very simple to form the scrap of castings.
2. The existence of particles, in the process of die casting is also a big hidden danger, that is, it will form a sticky die, if severe, it will also constitute die scrap.
3. There are many unbalanced eutectic arrangements and supersaturated solid solution elements in the aluminum alloy die casting, which improve the conditions of forming aluminum bonding.
The main influencing factors are mold, aluminum and die casting process. Through the joint efforts of various departments of die casting company, a relatively serious break has been made, which greatly reduces the occurrence of particles.
In the future work, we should strengthen the training of the staff and strive to improve the operation level of the operators; on the basis of production practice, we should constantly analyze problems, sum up experience, reduce or prevent the occurrence of particles, adhesion of aluminum, surface roughness, scratches, and other defects, so as to improve the company's product quality, casting yield and production efficiency.
