During the processing and production of aluminum alloy castings, due to many factors such as technology, molds, raw materials, etc., there will be a variety of quality problems in aluminum alloy die castings. We will also introduce solutions to these quality problems.
Carbon deposits. What is carbon deposition? It is the dark oxide on the surface of the aluminum alloy casting, which can usually be removed by wiping it with 0 # emery cloth. This kind of problem can usually be checked by visual inspection. The problem of carbon deposits in aluminum alloy die castings is because after the mold is continuously produced, release agents or other impurities are accumulated in the mold and adhere to the product surface. In order to avoid the problem of carbon deposits in the die castings, we recommend that the processing unit clean the molds regularly to keep them clean.
Lack of or fleshy meat. This problem is easy to check out. If there is more or less part of the surface of the die casting, it is a problem of fleshy or lack of meat. This is because after the mold is continuously produced, cracks or other failures occur, which will cause the surface of the aluminum alloy die-casting to be short or fleshy. How to solve this problem? It's simple, repairing the mold is all you need.
