Decorative electroplating
Decorative electroplating is mainly used to embellish objects. Among other things we can offer surface refinement as chrome plating as well as gilding and silver plating of jewellery up to cutlery.
Functional electroplating
Functional electroplating is mainly used for corrosion protection and wear protection. Furthermore, the electrical conductivity can be increased by the surface coating of contacts with the aid of galvanic silver plating and gold plating.
Rhodium - Electro plating
Rhodium is one of the platinum metals. This very valuable metal is distinguished by its extremely hard surface during electroplating and is chemically very resistant. It often acts as a tarnish protection for silverware.
Gold - Electro plating
Like hardly any other metal, electroplated gold plating has a very broad and varied range of applications. Gold has very good electrical conductivity, is virtually corrosion-free and is therefore used in technical applications.
Nickel - Electro plating
The good physical and mechanical properties of nickel electroplating are characterised by its hardness, wear resistance and tensile strength. The nickel coating has a silver-like colour with a matt to shiny good appearance and is also in demand for its corrosion resistance.
Silver - Electro plating
We offer various processes of galvanic bright silver plating as well as soft and hard silver plating. Silver has good formability and ductility and very good electrical and thermal conductivity. In addition, we are specialists in the silver plating of contacts and connectors.
Chrome - Electro plating
Chrome electroplating is used in the decorative and technical fields. For example, matt to glossy coatings with good corrosion protection properties can be produced. Galvanic chrome coatings have a shiny silver colour, high hardness and wear resistance and retain their shiny appearance.
Copper - Electro plating
With its reddish colour, copper electroplating is interesting for decorative applications and is easy to polish. In the technical field, copper is used as an intermediate layer before silver plating or nickel plating of copper and copper alloys.
Tin - Electro plating
Tin electroplating provides good chemical resistance and solderability. In the functional area, for example, tin plating of electrical contacts is used for the electronics industry.
Electroplating or electroforming is the term used to describe processes that use electrochemical processes to create metallic deposits on a self-conducting material. Today, they are mostly used to coat surfaces.
Electroplating, which was once used to create statues and monuments, is hardly used today. The technique of electroplating was made possible by the invention of batteries by Alessandro Volta around the year 1800. He invented this battery in connection with the research of Luigi Galvani, who also gave his name to today's galvanization.
During his experiments, Volta discovered, among other things, that copper was deposited on an iron rod that was connected to the negative pole of his battery and immersed in a copper sulphate bath. He also immersed a copper rod, which was connected to the positive terminal, in the solution. This simple procedure is still used today by hobbyists to enhance workpieces with copper luster.
Later, the first documented gilding was carried out by one of Volta's students in 1805, and the process was increasingly used industrially from 1840 onwards. From around 1850, life-size statues were produced comparatively cheaply using the process, and the triumph of electroplating had begun.
Over the centuries, electroplating has developed into a mature process with numerous possible applications. In addition to plastic electroplating and the application of metallic coatings, a distinction is made between decorative and functional applications. The enhancement of surfaces is characteristic of one use of the technique. Fashionable jewelry, for example, is often gold-plated, silver-plated or coated with other metals. Typical examples of objects enhanced by electroplating are chrome-plated components in motor vehicles, silver-plated cutlery or shiny metallic plastic parts.
However, electroplating is much more important in the field of functional applications. Because the thickness of the coating can be controlled very well and, if carried out professionally, is also uniform, workpieces can be coated in a variety of ways. Technically, it is also possible to make plastic components electrically conductive, which expands the field of application of electroplating immensely. For example, screws are galvanized for corrosion protection, machine parts are hard chrome-plated for longer durability and electrical contacts are gold-plated, silver-plated or copper-plated for better conductivity. The field of functional electroplating includes mold making for injection molding machines and lithographic electroplating molding technology, which was only invented around 1980.
In Germany alone, around 2100 registered companies in the sector currently generate annual sales of 8.3 billion euros and employ around 60,000 people. Training to become an electroplater, which today is more simply known as a surface coater, takes three years in Germany and four years in Switzerland. Further training as a technician is possible, and if you have a university entrance qualification, you can also study or train as a master craftsman.

What is electroplating?
Electroplating is a process that coats metal surfaces with a thin layer of metal through an electrochemical reaction. This electroplating protects the component from corrosion, improves its electrical conductivity or gives it an aesthetic finish.
The principle is based on the deposition of metal ions on a conductive surface. The workpiece is immersed in an electroplating bath in which a metal solution is activated by an electric current. This causes metal particles such as nickel, chrome, silver or gold to be deposited evenly on the surface. This makes electroplating one of the most precise and efficient methods of surface finishing.
This process is also frequently used in the jewelry industry. Anyone who has jewelry electroplated receives a high-quality coating of gold, rhodium or silver, which makes the piece of jewelry more durable and protects it from tarnishing. The process also makes it possible to enhance the appearance of cheaper metals and give them a sophisticated look.
Dresdner Silber und Metallveredlung GmbH uses state-of-the-art technology to ensure long-lasting, precise electroplated coatings. Our company specializes in functional and decorative electroplating that meets the highest quality standards.

Which materials can be electroplated?
Electroplating is often used for steel, copper, brass, aluminium and zinc to improve their corrosion resistance, conductivity or wear resistance. Electroplating can be used to coat these base materials with metals such as nickel, chrome, gold or silver.
In industry, steel or copper is often electroplated to make it more resistant. In the automotive industry in particular, many components are coated with nickel or chrome to increase their durability. In electronics production, a silver or copper coating ensures better conductivity and lower contact resistance.
Electroplating is also a proven method for jewelry. Anyone who has jewelry electroplated receives an even gold coating or rhodium coating, which not only ensures an elegant appearance, but also prevents the piece of jewelry from tarnishing or being damaged by external influences.

What are the advantages of electroplating?
Electroplating offers numerous advantages for both industrial and decorative applications. One major advantage is the high level of protection against corrosion, as the metal coating protects the underlying material from environmental influences such as moisture, acids or chemical stresses. Steel or copper in particular benefit from electroplating, as it considerably extends their durability.
In addition to corrosion protection, electroplating also increases the mechanical resistance of a component. A nickel or chrome coating makes surfaces harder and protects them from abrasion and scratches. In the electronics industry, a copper or silver coating also improves electrical conductivity, making components more powerful.
Another advantage is the visual enhancement. In the jewelry industry in particular, it is common to have jewelry electroplated in order to apply a gold coating, rhodium coating or silver coating. This makes jewelry look higher quality and keeps it shiny for longer. Electroplating is also used in the automotive industry to finish components with chrome and give them a long-lasting, shiny appearance.
Thanks to modern electroplating technology, our company is able to offer everything from high-precision protective coatings to decorative coatings with a sophisticated look.

How does the electroplating process work?
Electroplating is an electrochemical process that takes place in several steps. First, the component is thoroughly cleaned to remove impurities and oxide layers. It is then immersed in a solution containing metal ions of the desired coating material.
An electric current is applied to this solution. The metal ions from the bath are deposited evenly on the surface of the component. The coating thickness can be individually determined depending on the current intensity and duration of the process. Precise control is particularly important when electroplating industrial coatings in order to ensure an even layer without material loss.
The process can be adapted for different purposes: While nickel or chrome is often used to protect components, gold or silver is mainly used for decorative purposes. Anyone who has jewelry electroplated benefits from a shiny and durable surface that makes the piece of jewelry more valuable.

Why should you have components professionally electroplated?
Electroplating is a high-precision process that requires specialist knowledge and experience. Professional electroplating not only ensures a uniform and durable coating, but also exact adaptation to the respective requirements.
Incorrect electroplating can lead to uneven layers, poor adhesion or loss of material. It is particularly important for industrial components or high-quality jewelry that the coating is applied perfectly. Anyone having jewelry electroplated should ensure that the gold or rhodium coating adheres perfectly and is not too thin or too thick.
