We provide a complete color gradient plating service from 10K to 24K, leveraging precise color ratio technology and electrochemical deposition processes to achieve accurate reproduction of gold, rose gold, white gold, black gold, and other colors. By optimizing electrolyte formulations (e.g., adding rare earth elements to enhance color stability), we ensure plating color fastness reaches Level 5 or above (ISO standard), with excellent sweat corrosion resistance and anti-sulfidation properties, extending the lifespan of jewelry. For different substrates (copper, silver, stainless steel, titanium, etc.), we have developed compatible pre-treatment processes to ensure plating adhesion passes the cross-cut test at ≥4B grade, avoiding peeling issues during daily wear.

Our plating services cover various fields such as jewelry, watches, and eyewear, providing surface treatment for new products as well as re-plating solutions for restoring old accessories. For example, we restored mid-20th-century gold-plated jewelry for a renowned jewelry brand using micro-current activation technology to remove oxidation before re-plating, restoring the original color. We also provided 18K gold plating on stainless steel for a smart wearable device company, solving the challenge of bonding dissimilar metals by adding an intermediate transition layer.

In terms of cost-effectiveness, our precious metal plating costs are over 40% lower than traditional solid precious metal processing, making it particularly suitable for brand upgrades and product premiumization. We currently support small-batch orders with a minimum of 50 pieces and offer custom color sample services to help clients accurately match brand colors.
