Automatic electroplating plants at Rosenberger

Surface Treating Technologies


For More than 60 Years the Rosenberger Group has had its Own Electroplating Shop for Finishing Products

Innovation and competence ensure resource-saving, energy-efficient electroplating is an essential component in the material flow. After all, the quality of a surface coating depends greatly depends on the existing process capability to produce consistently high-quality workpieces. The most important components are: modern process monitoring systems and a pronounced material competence - disciplines which the Rosenberger Group has always regarded as an indispensable factor in the manufacture of its products.


What is Electroplating?

Electroplating is the coating of surfaces with metals. It is used to apply a functional layer of only a few µm (micrometer) thickness to the base material. The purpose of electroplating can vary depending on the products concerned. For example:

  • Protection of the product from corrosion
  • Visual enhancement of the product in the form of smooth or shiny surfaces
  • Optimization of functionality

Electroplating is also a key technology for industrial sectors such as the automotive, telecommunications and electrical industries.


Production Facilities

From the smallest components to mass refinements: Different production facilities in the surface technology area at Rosenberger ensure a flexible production process. This enables the required functional property to be applied to base materials of any size. These may be for end products as well as those needing further processing and production by the company.

All materials undergo three process steps. The process-determining work flow - the coating - is always preceded by a pre-treatment such as degreasing. Post-treatment includes, for example, drying or selective coating of the product.

Quality Management

Control with competence: Constant monitoring is essential for achieving consistently high quality processes and products as well as environmentally-friendly production. With the help of innovative measuring equipment and galvano-specific analysis methods, production reliability and capability is guaranteed. Material analysis is subject to just as much control as wastewater monitoring. Because resource efficiency and environmental protection are the basis of sustainable and innovative production in the Rosenberger Group.

Environmental Protection

Success with responsibility: In its role as a globally operating surface coating company the Rosenberger Group understands its responsibility for protecting the environment. The electroplating industry, in particular, produces wastewater that requires special treatment, recycling or disposal. In addition to strict compliance with all the requirements of the Water Resources Act, the Federal Immission Control Act and the Ordinance on Major Accidents, Rosenberger takes a stringent and innovative approach to meeting all environmental standards.

How does Electroplating Work?

Electroplating is Based on the Principle of Electrolysis

In this process metals are coated with a layer of another metal. In order for the coating metals to accumulate on the workpieces they are switched as a cathode (negative pole). The anode (positive pole) consists of the superior coating material. The electric current detaches metal ions from the anode, which are then located in a salt solution. The ions discharge at the cathode, where they settle as metal atoms. Suitable electroplating baths are, for example, copper sulphate for copper plating.
