How to carry out anti-corrosion treatment for stamping parts

The stamping and drawing parts need to do a good job of anti-corrosion treatment in the whole process of manufacturing, so as to ensure a reasonable prevention of corrosion in the product application process. Based on many years of experience, Precision has refined some anti-corrosion treatment methods for stamping and drawing parts for your reference. 1. Epoxy zinc-rich primer coating, heating the stamped and stretched parts before spraying can improve the adhesion of epoxy zinc-rich primer and accelerate dryness. 2. The mixed mortar lining and special coating can improve the corrosion resistance of the lining of the stamping and drawing parts. 3. The epoxy resin asphalt mortar coating is a component coating, which has high adhesion and a very smooth surface. 4. The epoxy resin porcelain lining has certain limitations in application due to the high degree of difficulty in the manufacturing process and the increase in cost. It has high adhesion and smoothness, and is a corrosion-resistant coating for stamping parts. 5. Aluminate cement coating or potassium thiocyanate concrete coating, both of these special concrete coatings are suitable for internal corrosion protection of stamping and drawing parts, and improve the ability to resist corrosion. 6. Polyurethane material coating is a new emerald green special coating developed for new products to meet the requirements of environmental protection. It has excellent wear resistance and corrosion resistance. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
