Anti-rust knowledge about precision castings:

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

The following is to share with you the knowledge about rust prevention of precision castings. Corrosion or discoloration in the atmosphere caused by oxygen, moisture, acid, salt and humid air is called rust or rust. Metals or alloys can transform metal surface layers into low-strength compounds. Therefore, investment casting often requires mid-term rust prevention treatment. The method of preventing rust is generally to choose water anti-rust or oil anti-rust. Regardless of the rust prevention method selected, the casting must be scrubbed first to remove the dirt on the surface and promote the formation of a passivation film. The composition, temperature and use of the brush. After pouring, blow dry with dry hot, dry compressed air, and then perform anti-rust treatment.
