The principle of yellow chromate zinc plating mainly includes chemical and electrochemical reaction processes. In the process of zinc plating, when the surface of the zinc layer is in contact with the chromate solution containing hexavalent chromium, the surface of the zinc layer is dissolved by the acid to produce hydrogen, and the reduction reaction of the dichromate ion occurs, and the insoluble chromate film with chromium hydroxide as the main body is formed. This fine film has no gaps and can protect the zinc coating under high humidity environment to prevent further oxidation.
Excellent corrosion resistance:The zinc coating provides basic anti-rust protection, and the yellow chromate (hexvalent chromium or trivalent chromium conversion film) further closes the surface pores, enhances the corrosion resistance, and extends the service life of the product in harsh environments such as damp and salt spray. More resistant to oxidation, chemical corrosion and wear than a single galvanized or ordinary coating.
Cost-effective and production efficiency: Low material cost, carbon steel prices are lower than stainless steel and other alternative materials, suitable for mass production. High efficiency of stamping process, rapid prototyping, suitable for large-scale manufacturing, reduce the cost of a single piece.
Beautiful and identification: The surface presents a uniform light yellow or rainbow luster, both rust and beautiful effect, suitable for the appearance of the scene.
Environmental protection and compliance: If the trivalent chromium passivation process is used (instead of traditional hexavalent chromium), it can meet environmental regulations such as RoHS and reduce environmental hazards. Corrosion resistance Prolongs replacement cycle and reduces resource consumption.
Customized design: Customized shape, size, hole position, etc. according to customer needs, perfectly matching equipment or assembly needs, reducing installation adjustment costs. Integrated stiffeners, anti-slip lines, mounting interfaces, etc., improve functionality (such as shock absorption, heat dissipation, stability).
Construction industry: In the construction industry, yellow chromate zinc plated stamping products are often used to build fences, stairs and other structures. These products are not only beautiful, but also can effectively resist the erosion of harsh environments.
Automotive industry : In the automotive industry, stamping products are used in various auto parts to ensure their durability and safety.
Power equipment: In the field of power equipment, yellow chromate stamping products also play an important role in ensuring the durability and safety of zinc plated parts.
Home appliances and consumer products: washing machine counterweights, air conditioning brackets, etc., optimized space utilization through custom stamping design. Patio sunshade base, metal table and chair connectors, resistant to rain and UV erosion.
Electronic and electrical equipment: Installation base for server cabinets and power control boxes, providing electromagnetic shielding (metal) and moisture protection. The custom stamped structure can be integrated with heat dissipation holes for electronic component heat dissipation modules.
Industrial machinery and equipment: Load-bearing bases for heavy machinery (e.g. punches, injection molding machines, CNC machine tools) that take advantage of the high strength and corrosion resistance of carbon steel to ensure long-term stable support. As a structural part of a conveyor system, assembly line or fixed support, it can adapt to vibration, oil and humidity in a factory environment.

FAQ:
1Q: How is steel stamping different from other metal fabrication processes?
1A: Steel stamping is a metal fabrication process that involves shaping and forming steel sheets or strips using a stamping press and specially designed dies. Unlike other processes like casting or forging, stamping primarily relies on the use of dies to cut or shape the material.
2Q: Can the custom stamping base be made according to specific drawings and requirements?
2A: Yes, the custom stamping base can be manufactured to meet specific drawings and requirements. All of our products are made according to customer drawings.
3Q: What is the process of custom design?
3A: Process: Demand communication → drawings /3D modeling confirmation → mold development → sample testing → mass production.
4Q: What is the thickness range of the material used in the stamping process
4A: The thickness range of materials used in the stamping process is mainly between 0.15mm and 2mm .
5Q: Can you provide free samples to customer?
5A: Yes, but customer needs to afford the samples freight cost.
