1. Decompose the gas generated 

Some mold parts produce volatile gases, most of which are corrosive with certain impact on parts such as erosion or rusting; therefore, after processing, do shut down the production equipment to decompose or exhaust gases immediately, and coat with rust inhibitor;  

2. Wipe away the cooling water 

The professional processing enterprise will appoint a worker to wipe away cooling water; due to high temperature in production of the parts, it is necessary to provide cooling water to cool down the parts instantly; however, the steam is produced when cooling down, resulted in oxidization and rusting after a long soaking in steam; therefore, it is also a method to wipe off cooling water or excessive water rapidly; 

3. Eliminate the carbides

3. Eliminate the carbides

The above solutions are used to prevent rusting of parts in processing; for processing, the rusting and corrosion shall be prevented not only during production, but also during transportation and marketing; therefore, the finished mold parts shall be wrapped with plastic film to isolate from air and prevent damage and corrosion.
