stamping Stretch piece In the production process, it is necessary to do a good job of anti-corrosion treatment, so as to effectively avoid corrosion in the process of use. Let's take a look at the anti-corrosion treatment method of stamping stretch parts together with the small series of Heju precision hardware factory.
 
1. Asphalt paint coating, stamping before painting Stretch piece Preheating can improve the adhesion of asphalt paint and accelerate drying.
 
2. The cement mortar lining with special coating can improve the corrosion resistance of the lining of the stamping tensile parts.
 
3. Coal tar epoxy coating is a two-component coating with high adhesion and smooth surface.
 
4. Epoxy ceramic lining is a kind of anti-corrosion coating for stamping parts because of its difficult manufacturing process and high cost, so it has certain limitations in use and has high adhesion and finish.
 
5. Aluminate cement coating or sulfate cement coating, these two kinds of special cement coating are suitable for internal corrosion protection of stamping tensile parts and improve the ability of corrosion resistance.
 
6. Polyurethane coating is a new green special coating developed to meet the needs of environmental protection. It has good wear resistance and corrosion resistance.

Dongguan Heju Precision Electronic Technology Co., Ltd. is a company focusing on precision Stretch piece The processing of stamping plant, high productivity, high material utilization, products with a certain dimensional accuracy and low surface roughness.
