Common surface oxidation of aluminum alloy die casting

　　First, find the cause

　　After a long time of observation, the study found that there are many reasons for the surface oxidation of aluminum castings, and the main reasons are the following: aluminum casting

　　The equipment of the part is not cleaned well after use, resulting in a lot of material impurities sticking on the surface of the casting, and over time,

　　It is oxidized, or the solution in the casting, which generally contains metal elements and is soaked in the equipment for a long time, will also produce "oxidation;"

　　There is also the improper use of equipment in the operation process, resulting in damage to the equipment and oxidation.

　　Second, solutions

　　Encounter the above oxidation reasons, we need to take the right measures according to the actual situation, remember each time after the use of castings

　　Timely clean, so that the surface of the casting no other impurities and pollution; Improve the pouring capacity of the object, using appropriate

　　The mode of production; Clean the metal solution in the equipment in time, and pour it with water after cleaning, repeat several times, and completely clean it

　　To wash; For the treatment of production materials, the impurities contained in the materials are effectively removed and the service time of the equipment is appropriately reduced.
