Knowledge about rust prevention of Dongguan precision castings

Knowledge about rust prevention of Dongguan precision castings:

Casting structure design: On the premise of ensuring its working performance and mechanical properties, comprehensive consideration of the requirements of the casting process and alloy casting form on the casting structure, whether the structural design is reasonable has an important impact on the quality, productivity and cost of casting.

What is shared with you below is knowledge about rust prevention of Dongguan precision castings. Corrosion or discoloration in the atmosphere is caused by oxygen, water, acid, salt and humid air. This is what is called rust or rust. Metals or alloys can be The metal surface layer is converted into a low-strength compound. Therefore, mid-term anti-rust treatment is required during melting. For anti-rust methods, water anti-rust or oil anti-rust is generally selected. No matter which anti-rust method is chosen, the castings should be brushed and cleaned first to remove the surface. Dirt promotes the formation of a passive film. The composition, temperature and use of the brush. After pouring, dry it with dry heat and boring compressed air, and then carry out anti-rust treatment.
