Cash die-casting parts are becoming more and more popular, and China die casting factory is becoming larger and larger. Although die-casting plants are constantly improving the quality of die-casting parts, some problems still exist and have not been solved. Although some are solved, they will inevitably commit, such as the problem of lack of material (shrinkage dent) in castings.
In terms of die casting machine: (1) The nozzle hole is too large to cause the aluminum alloy material to flow back and shrink, and the resistance is too small and the material is insufficient to shrink. (2) If the clamping force is insufficient, the flash will also shrink. Check the clamping system for any problems. (3) Whether the tonnage of the die-casting machine is sufficient, try to choose a large-tonnage die-casting machine, and check whether the screw and barrel are worn. All of these may cause the casting lack of material, which is shrinkage and depression.
Therefore, we can only try to avoid this kind of error. When it is unavoidable, we can only try our best to solve this problem. For example, aluminum die casting can also have this kind of problem. chinaweilong.cn
