Weltkarte Heiche Standorte


As a strong team, we in the Heiche Group bundle special skills and tried and tested know-how in surface coating and refinement. Each location works with a different focus. The Heiche factories in Baden-Württemberg, Bavaria and Saxony as well as the factories of Metallveredlung Döbeln GmbH and Gt Oberflaechen GmbH, which are part of KAP Surface Technologies, contribute very individual strengths. In addition, we can also offer highly specialized finishing processes in our locations in the USA as well as in Hungary and Poland, which complement our broad, cross-location range of standard and special coating processes. The Heiche Group's unique portfolio for the coating and refinement of surfaces results from the cross-location synergies.

Even with careful casting techniques, some castings can have some porosity, which makes parts for the intended application unusable. Through our modern methods of impregnation, it is possible to seal cracks and sinkholes. The impregnated parts are characterized by excellent temperature and pressure resistance as well as a very good chemical …

The technical paints are applied in a spray process, whereby we use both our own and customer-specified paints. We paint on a wide variety of base materials and can choose from a large number of suitable pre-treatment systems that we have in-house. To protect the environment, we are increasingly using water-based paints. But we also use low-solvent …

Adhesion Promotion

We can offer a process that promotes bonding characteristics from rubber-metal combinations. Depending on the base materials (steel, aluminum or plastics) we can process silane, phosphate and Cr (VI) -free conversion layers for different bonding systems. Our coating equipment can accommodate drum or rack handling, as well as we can produce a …

Anodizing / Hard Anodizing

E coat anodizing generates an aluminum ceramic layer, through an electrolytic oxidation process. In comparison with the base material, the wear resistance increases tremendously. The process is also named as anodization. It can achieve a layer thickness between 3 and 70microns (0.11 and 2.8mil) depending on the procedure. The layers are …

Cathodic Dip Coating (e-coat)

Coating layers that are built through the cathodic dip painting process, have one of the best corrosion protection characteristics in the metal coating industry. They also have a uniform layer structure. We have coated the base material steel, aluminum, zinc and magnesium die-cast components with a layer thickness between 10 and 45 microns. Our …

Chemical paint stripping

When painting components, it can happen that the painted surface does not meet the required quality standards. Then, as a rule, the only thing that helps is stripping. There are basically 3 different options for stripping: a) Thermal paint stripping. The paint is burned at high temperature.b) Mechanical removal of the paint, e.g. by sandblasting.c) …

Degreasing / Etching / Washing

We clean and activate metallic surfaces as a pretreatment for subsequent downstream processes such as gluing, bonding or welding. We use this developed material-specific method especially for light metals. Through various etching processes for aluminum and aluminum alloys, metallic clean surfaces can be achieved, which can provide excellent …

To the process


Through the Conversion / Passivation coating, metals are covered with a non-metallic, Cr (VI) -free protective layer. In the HEICHEGROUP a variety of metal surfaces such as aluminum, magnesium, zinc die casting or steel can be passivated with a variety of procedures, including multi-metal pre-treatments. Conversion / passivation coatings offer …

Phosphating, depending on the crystal structure, is very suitable as a primer for subsequent coatings. It improves drawing, sliding properties and also guarantees a temporary corrosion protection, especially in combination with suitable oil. In the HEICHEGROUP the following phosphates used:Manganese phosphate , Zinc phosphate & Zinc calcium …

Powder Coating

Powder coatings are ideal for mechanically highly stressed parts due to their excellent stone chip and scratch resistance. Typical base materials are steel, aluminum, zinc die casting and cast iron. With a thickness between 40 and 100 microns, powder coatings also achieve excellent corrosion protection. In addition it has a great price-performance …

Sol-Gel-Coating (Nano Technology)

Sol-gel and Nano coating layers are applied to specific pre-treated metal surfaces by a dipping or spraying procedure. Although the layer thickness is thin, the corrosion resistance is excellent. Also the Nano Coating has easy-to-clean properties and has great temperature and chemical resistance. Due to the multifunctional process method, we can …

Chromium VI-free aftertreatment

In the case of chromium (VI) -free post-treatment, conversion layers are produced on freshly deposited zinc or zinc alloy coatings by treatment with a passivation. The freshly deposited coating reacts with the passivation solution to form a thin film (approx. 0.05 μm to 0.5 μm) of complex reaction products that protects the metallic coating. The …

Inside Rinsing of coolers

The internal rinsing of the cooler forms the background for the conductivity rinsing in fuel cell applications. The requirements of the OEMs for the conductivity in the cooling circuit are usually between 5 and 100 µS / cm. The conductivity of a coolant is around 2 - 6 μS / cm, deionized water is around 5 - 8 μS / cm. Since an unflushed cooler …

Over half a century of experience in surface coating

The history of the Heiche Group goes back to 1965. Right from the start, coating and finishing were central issues in family Heiche's company, which initially operated as a jewelry and silversmiths. Over the years, the portfolio of techniques and processes for surface coating has been steadily expanded and new know-how has been continuously acquired.

With the change of generation in 1998, the course was set in the direction of expansion and the goal of market leadership in the area of surface finishing was firmly anchored in the corporate philosophy. We then expanded nationally before we also conquered the international market with agencies in Hungary, Poland and the USA.
