Sand casting aluminum housing is widely applied in the kind of military electronic control box in China.With a sand mold casting aluminum housing surface film quality problem of the blister and low product qualified rate in the process of hot and humid test,we do the analysis from the base material,operation personnel,paint and.Draw the film blister barb causality diagram,list the reason to the paint film in bubbly,analyze each reason,elimination and test verifica-tion,find the paint film is the main reason for the blister,and formulate the corresponding countermeasures.Finally we solve the quality problems,improve the quality of the paint on the surface of the box body and provide valuable experience for the machining of the similar products in the future.
