Precious Metal Electroplating for Coins, Medals and Jewelry

Electroplating, or galvanic technology, has a long and rich tradition and is considered one of the most important surface finishing techniques in the field of metal and precious metal refinement. Decorative electroplating encompasses everything from the galvanization of pure materials to chrome plating of components and gold plating of jewelry and precious metal items such as medals or coins. Today, it is an indispensable part of metalworking. While some trace its origins back to ancient times, it is widely accepted that Luigi Galvani, an Italian physician and the technology’s namesake, developed this sophisticated technique in the 18th century by leveraging electrochemical processes.

During the electroplating process, metal ions are deposited onto the surface of a metallic object. The workpiece to be coated is placed at the negative pole within an electrolytic bath of metal salt solution, while the metal to be deposited is attached to the positive pole. Direct current passed through the solution causes the metal ions from the anode to dissolve and then deposit onto the cathode — the workpiece — effectively coating it in the desired metal. This process significantly enhances the physical and mechanical properties of the coated surfaces.

Traditional electroplating methods include coatings with gold, silver, and copper. A gold electrolyte, for example, allows the formation of high-quality gold layers on various surfaces. Decorative electroplating ranges from pure material coatings to surface finishing of components and gold plating of jewelry and precious metal items like medals or coins.

Today, electroplating is essential in modern metal processing. While its conceptual roots may go far back, it was Galvani in the 18th century who gave the field its electrochemical foundation and technological depth.

 

At MünzManufaktur, we offer a broad range of services and products known for the highest quality and individuality. Both base and precious metals are used in the coating of workpieces, allowing virtually unlimited finishing options. Whether it's jewelry or decorative components – electroplating enables surface refinement tailored to customer preferences. Classic techniques like zinc plating, copper plating, silver plating, or gold plating are available, along with chrome plating for particularly demanding designs. The result is unique outcomes that align perfectly with each customer’s style.

Our jewelry service at MünzManufaktur is defined by precision and expert craftsmanship. Though the concept of electroplating may seem simple, it requires careful adjustment of numerous parameters. Factors like pH levels, temperature, and particle concentration must be meticulously calculated and harmonized. Only through this precise control can we guarantee top-tier results that meet even the most stringent demands.

Electroplating is thus a fascinating yet demanding field, requiring deep knowledge of electrochemical metal finishing. At MünzManufaktur, we combine technical expertise with creative craftsmanship to deliver products and services of the highest caliber.

 

Since the minting and distribution of precious metal investment products like coins or gold bars have always been a core focus of our business, electroplating as a key refinement technique naturally plays a central role in our daily work.

Our innovative production processes are tailored to the needs of jewelers and manufacturers of decorative components – we specialize in custom-made solutions to your specifications. We are happy to assist you in creating a product that stands out through its superior coating quality.
