How to solve the cracking on the surface of aluminum alloy die castings?

Summary: 1. The iron content or silicon content in the aluminum alloy is too high. 2. The content of harmful impurities in the alloy is too high, which reduces the plasticity of the alloy. 3. Aluminum alloy die-casting mold, especially the overall temperature of the mold cavity is too low. 4. Where there are drastic changes in the wall thickness and thickness of the casting, the shrinkage is blocked, and the sharp corners form stress. 5. The mold retention time is too long and the stress is large. the solution: 1. Correctly control the alloy composition. 2. Change the casting structure, increase the angle, change the draft angle, and reduce the wall thickness difference. 3. Change or increase the ejection position, so that the ejection force is uniform.
