Reasons and solutions for surface oxidation of aluminum casting parts

1. The cause analysis for surface oxidation of Aluminum Casting Parts.

After our observation and research, it is found that there are many factors that cause the surface oxidation of Aluminum Alloy Investment Castings, mainly due to the following reasons. , oxidized or the solution in the casting generally contains metal elements, and it will also oxidize if it is soaked in the equipment for a long time; or the equipment is improperly used during operation, causing damage to the equipment and oxidation.

2. The solution for surface oxidation of aluminum alloy castings.

In the face of the above oxidation reasons, we need to take correct measures according to the actual situation, clean the aluminum casting parts in time after use, and keep the casting surface free of other impurities and pollution; improve the pouring ability of objects, and adopt appropriate production methods to produce, timely Clean the metal solution in the equipment, pour it with clean water after cleaning, repeat several times, and thoroughly clean it; for the treatment of production materials, effectively remove the impurities contained in the materials, and appropriately reduce the use time of the equipment.
