The next thing to share with you is the anti-rust knowledge of precision casting parts. The corrosion or discoloration of metals or alloys in the atmosphere due to oxygen, moisture, acid, salt and moist air is called rust or rust, which can turn a metal surface with a very high strength into a very low strength compound. For this reason, the molten die castings often need to carry out medium-term anti-rust disposal.
Anti-rust method, usually choose water Agent anti-rust or oil anti-rust. No matter which method is chosen to rust, the castings should be washed in advance to remove the surface of the dirt, and promote its formation of passivation film. The composition, temperature and usefulness of the scrubbing solution. After washing the castings to use hot, boring compressed air to blow dry, and then for anti-rust disposal.
