How to prevent corrosion in metal stamping processing in stamping plants

In daily life, the application of Metal Stamping parts is becoming more and more common. And customers also have higher and higher requirements for stamping parts with the bulk requirements. The first thing to bear is the anti-corrosion measures in the process of metal stamping processing. This can meet the anti-corrosion characteristics, and the use time of stamping parts can be longer and longer.

Although the stamping parts produced by the factory currently meet the standards required by the industry, most of them can meet certain anti-corrosion requirements. But so far, more stamping parts have a certain decorative effect. As an appearance part, the customer‘s requirements are even higher.

Therefore, it is necessary to do a good job of anti-corrosion treatment during metal stamping processing, so as not only to avoid corrosion events in the production process to improve the pass rate, but also to increase customer satisfaction during acceptance. Here are several main anti-corrosion measures:

1. Asphalt paint coating, preheating stamped parts before painting can improve the adhesion of asphalt paint and accelerate dryness;

2. Cement mortar lining with special coating can improve the corrosion resistance of stamping parts lining; 3. Metal stamping parts epoxy coal asphalt coating is a two-component coating, which has high adhesion and a very smooth surface.

4. Epoxy ceramic lining has certain limitations in application due to the difficulty and high cost of the manufacturing process, and it has high adhesion and smoothness. It is an excellent anti-corrosion coating for stamped parts.

5. Aluminate cement coating or sulfate cement coating, both of which are suitable for internal corrosion protection of stamped parts, improving the ability to resist corrosion.

　 6. Polyurethane coating is a new type of green special coating developed to meet the needs of environmental protection, with good wear resistance and corrosion resistance.
