welcome to Berlin

“Stern-Radio”, under this name radio sets were produced in the GDR. The main plant in Berlin-Marzahn also included the electroplating manufacturing plant in the present-day Springpfuhl industrial estate, which was acquired by the AHC almost two years after the fall of the Berlin Wall in 1991. Since then, a consistent path of modernization and automation has been taken, which continues to this day. Since 2019 we have been offering surface coating technology in Berlin as part of the Aalberts Group, including:

color anodizing of metals (aluminum)
hard coating,
electroless nickel plating,
plasma chemical coating.

Except for one manual electroplating system, all surface technology coating systems in Berlin today are fully automatic, including the documentation of all process parameters.

The Aalberts surface technologies plant in Berlin offers surface technology produced in a 3-shift operation with around 80 employees and regularly trains surface coaters.

our surface treatment services in Berlin

hard anodizing solution in Berlin with HART-COAT®

The HART-COAT® process, or HC for short, is an electrolytic treatment of aluminum that results in the formation of a hard and thick layer of aluminum oxide. With the HART-COAT® surface refinements, we hard anodize workpieces in Berlin for which a high degree of corrosion protection, wear resistance, dimensional accuracy, sliding behavior or insulation is required. HART-COAT® coatings are characterized by good adhesion to the base material. Compared to conventional anodized coatings, HART-COAT® coatings are thicker and more wear-resistant. HART-COAT® surface refinement is used in almost all technical areas in which aluminum parts are subject to special functional requirements.

electroless nickel plating in Berlin with DURNI-COAT®

DURNI-COAT® is a process for the chemical nickel plating of metals (electroless nickel). In this process, the electroless nickel coating in Berlin takes place as chemical deposition without an external power source.

The performance spectrum of DURNI-COAT® electroless nickel coatings ranges from chemical resistance, dimensional accuracy and optimum sliding properties to electrical conductivity and increased hardness. The coatings are deposited uniformly and true to contour. This ensures optimum finishing even for geometrically complex components.

Electroless nickel plating in Berlin with DURNI-COAT® is suitable for surface finishing of all low-alloy ferritic steels, cast iron materials, stainless steels, non-ferrous metals such as copper, brass or bronze, aluminum alloys and sintered metal materials.

The three most demanded properties in the application of electroless nickel coatings are wear protection, corrosion resistance and contour fidelity. This is followed by solderability, favourable friction behavior, high ductility and certain magnetic properties.

technical anodizing solution in Berlin

Technical anodizing is a coating for the functional, but also decorative finishing of aluminum and aluminum sheets. The coating is carried out in an acid electrolyte at temperatures slightly below room temperature. The workpiece is connected as an anode. In the course of the treatment, the workpiece surface is converted into a porous (dense), hard and wear-resistant aluminum oxide layer. Sealing closes the pores and greatly improves corrosion resistance. The layer thickness varies between 10 and 30 µm depending on the application and alloy.

Technically anodized aluminum parts and sheets offer increased corrosion and wear protection in almost all industries.

fields of application

Our coating company offers anodized aluminum services in Berlin to customers from various industries, including the construction industry, chemical industry, computer industry, electrical engineering, vehicle construction, household appliances and goods, lighting industry, aerospace industry, mechanical engineering, medical technology, furniture and fittings industry, optics/precision engineering, sports and camping industry, textile industry.

application examples

Aluminum components coated with KEPLA-COAT® in Berlin can be used in a variety of ways: they serve, for example, as geometrically complex rotors in turbo-molecular pumps. There, the crack- and pore-free layer of the workpiece prevents the penetration of reaction gases and thus provides the necessary protection against plasma etching processes, while at the same time withstanding the mechanical stress of extremely high speeds. KEPLA-COAT®-coated aluminum materials are also used as sealing rings, fixing discs, rollers, drums or cylinder tubes. Due to their high light absorption capacity, black KEPLA-COAT^® coatings are suitable for optical parts, diaphragms or radiant heaters, for example.
