Structure design of precision castings: to ensure the requirements of its working performance and mechanical properties, while taking into account the requirements of the casting process and alloy molds on the casting structure, a reasonable casting structure design has a great impact on the quality, production efficiency and production cost of the castings Impact.
The next step is to share the knowledge of rust prevention of precision castings. In the atmosphere, corrosion or discoloration caused by oxygen, water, acid, salt, and humid air is called rust or rust. This phenomenon can transform a very strong metal surface into a very low-strength compound. Therefore, it is usually necessary to carry out mid-term rust prevention treatment on investment castings. Use anti-rust method, generally choose water anti-rust or oil anti-rust. No matter which method you choose to prevent rust, precision castings must be washed in advance to remove dirt on the surface and promote the production of a passivation film. The composition, temperature and purpose of the cleaning fluid. The washed castings should be blown dry with hot air, and anti-rust treatment should be carried out immediately after drying the compressed air.
