our processes

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 …

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 …

To the process

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 …

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 / …

To the process

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 …

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 …

To the process

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 …

To the process

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 …

To the process

When sealing, we create a thin organic or inorganic protective layer about 0.5-2 μm thick on zinc or zinc alloy coatings. Sealing is generally carried out on passivated surfaces, with the sealing penetrating the …

To the process

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 …

To the process

As a process for the refinement of surfaces, galvanizing is proven and versatile. It is the most widely used and most cost-effective method for achieving reliable corrosion protection for numerous areas of application. …

To the process

The galvanically deposited zinc-nickel alloy meets the extremely high corrosion requirements of the automotive industry. This process is reliably commissioned in the most modern, fully automated systems. Zinc-nickle acid …
