about this location
welcome to Göppingen-Voralb (Eschenbach)
In 1970 the Ebersbach site was founded with the standard processes hard anodizing HART-COAT® and electroless nickel DURNI-COAT®.
In 2006 we moved to the new production facility in Göppingen-Voralb (Eschenbach district) with new, modern facilities and high capacities.
The production area is approx. 6,000 m². 140 highly motivated and qualified employees work in three shifts for you and coat more than 250,000 components daily.
Since January 2019, the former AHC plant in Eschenbach has been part of Aalberts Surface Technologies GmbH. With specially developed and patented processes such as hard anodizing with HART-COAT® and electroless nickel plating with DURNI-COAT®, components are refined to meet the increasing demands of industry.
“Our plant is characterized above all by customer-oriented solutions, high delivery reliability and short delivery and reaction times. We are able to coat both individual parts and large series. Our individual technical advice in advance also enables the realization of highly demanding customer projects.“

coating services from Göppingen-Voralb (Eschenbach)
The HART-COAT® surface treatment in Göppingen-Voralb (Eschenbach plant) protects aluminum workpieces against wear and corrosion, among other things, and is also characterized by very good adhesion to the base material.
HART-COAT® coatings are formed by anodic oxidation in an acid electrolyte of a special composition, resulting in an aluminum oxide layer on the component surface.
DURNI-COAT® is a nickel-phosphorus coating process for surface refinement. In addition to aluminium and steel, all other base materials can also be optimized by means of electroless nickel plating. Our DURNI-COAT® coatings are very well suited for applications with special requirements, because the performance spectrum ranges from chemical resistance, dimensional stability and optimum sliding behaviour to electrical conductivity and increased hardness.
The advantages are high precision, uniform coating thickness, especially for components with complex shapes, and series production reliability for almost all metals. The dispensability of an external power source makes chemical nickel plating additionally interesting.
Like hard anodizing (HART-COAT®), technical anodizing is a process of classical anodizing, which is carried out at relatively low temperatures in an acid electrolyte. The aluminum workpiece is connected as the anode. In the course of the treatment, the workpiece surface is transformed into a porous (dense), hard and wear-resistant aluminum oxide layer. By subsequent compaction the pores can be closed and the corrosion resistance is greatly improved. The advantages of technically anodized aluminum parts include good corrosion and wear protection.

application examples
In Göppingen-Voralb (Eschenbach), we use HART-COAT® (hard anodized) coatings in the automotive industry for valve pistons for automatic transmissions, parts for combustion engines, brake disc pots, pump parts for fire engines and components for control electronics, among other things.
In mechanical engineering, the DURNI-COAT® process is used to finish the boards for machines. The coating process is also used for water pump parts, components for piping systems, precision turned parts, castings, industrial valves and components for CNC lathes and milling machines.
With the DURNI-COAT®-AL process we coat, among other things, shift slides for automatic transmissions, pistons for steering systems, sealing discs, brackets and feed systems.
For aviation technology, for example, we finish handles and floor panels for helicopters with technical anodizing and HART-COAT®.
In the automotive industry, we use technical anodizing to finish brake components for motorcycles, profiles, cooling plates, fastening parts, housings, mounting plates, gear wheels, brush strips, covers, guides, consoles and door guide systems, among other things.
