What is medal plating process?
How Medal Plating Works
The medal plating process involves submerging the base medal into an electrolyte solution containing dissolved metal ions. An electrical current passes through the solution, causing metal particles to bond permanently to the medal's surface. This creates a uniform, durable coating that transforms the medal's appearance and properties.
Common Medal Plating Materials
Gold Plating
Gold plating remains the most prestigious option for awards and commemorative medals. The process typically applies 24-karat gold in thicknesses ranging from 0.5 to 2.5 microns, providing excellent corrosion resistance and lasting brilliance.
Silver Plating
Silver plating offers an elegant, cost-effective alternative with excellent reflectivity. However, silver-plated medals may require periodic polishing to maintain their luster due to natural tarnishing.
Other Plating Options
Medal manufacturers also utilize copper, nickel, and bronze plating for specific aesthetic effects or as base layers before applying precious metals.
Preparation and Quality Control
Successful medal plating requires meticulous surface preparation, including cleaning, degreasing, and sometimes applying primer coats. The base material—typically brass, zinc alloy, or pewter—must be perfectly clean to ensure proper adhesion.
Modern medal plating facilities employ strict quality control measures, including thickness testing and adhesion verification, to guarantee consistent results that meet industry standards.
Benefits of Professional Medal Plating
Professional medal plating enhances corrosion resistance, improves scratch resistance, and creates stunning visual appeal that reflects the significance of achievements being recognized.
