Causes and solutions of surface oxidation of aluminum die castings
1. Reason analysis

 

Through our observation and research, we have found that there are many factors that cause the surface oxidation of aluminum castings. The main reasons are as follows. The equipment of aluminum castings is not properly cleaned after use, resulting in a lot of material impurities adhering to the surface of the castings. , It is oxidized; or the solution in the casting generally contains metal elements, so it will be oxidized if it is soaked in the equipment for a long time; and the equipment is oxidized due to improper use of the equipment during operation.

Two, the solution

 

In the face of the above oxidation reasons, we need to take correct measures according to the actual situation, clean the castings in time after using them, and keep the surface of the castings free of other impurities and pollution; improve the casting capacity of the objects, and use appropriate production methods to produce; timely Clean up the metal solution in the equipment, pour it with clean water after it is cleaned, repeat it several times, and clean it thoroughly; for the processing of production materials, the impurities contained in the materials are effectively removed, and the use time of the equipment is appropriately reduced.
