The resistance of electroless nickel to most corrosive media effectively protects the base material or component.

Solution:
Electroless Nickel

Due to the rough surface of the anodised coating, there is very good mechanical interlocking with the lacquer coating.

Solution:
Anodizing

Intergranular corrosion can occur at the grain boundaries due to certain alloy constituents. The component becomes brittle. Anodizing and post-compaction counteracts this effect.

Solution:
Anodizing

State-of-the-art bonding techniques are used in automotive engineering. In order to ensure a secure connection at all times, it is necessary to produce a uniform, residue-free surface. This cleanliness can be achieved using special processes approved by the automotive industry.

The rough surface of the anodised layer results in very good mechanical interlocking with the adhesive layer.

Lösung:
Anodizing

The ceramic anodised layer reliably prevents contact corrosion.

Anodizing

With the ZinKlad MGL process, Holder Oberflächentechnik offers protection for fasteners that are installed in contact with magnesium.

The ZinKlad MGL process reliably prevents contact corrosion with magnesium.

Holder is an officially approved supplier to the Volkswagen Group for the TL 194 specification.

Solution:
Zinc (ZinKlad MGL)

Under special climatic conditions, corrosion can occur in aluminium components. The corrosion resistance of aluminium can be improved by appropriate passivation.

The resistance of electroless nickel to most corrosive media effectively protects the base material or component.

Solution:
Electroless Nickel

The resistance of electroless nickel to most corrosive media effectively protects the base material or component.

Solution:
Electroless Nickel

The resistance of electroless nickel to most corrosive media effectively protects the base material or component. This effect can also be achieved by anodizing surfaces – but is much less effective there than with electroless nickel.

Electroless Nickel

Aluminium components are protected against corrosion by a low-phos coating and can be welded at the same time. A double benefit for you.

Lösung:
Chemisch Nickel

Optically different areas (welded and unwelded) can be optically upgraded or adjusted by a uniform semi-matt electroless nickel coating. This increases the value of your components and gives you advantages for your customers.

Lösung:
Chemisch Nickel

Mechanical friction causes wear on steel components. Surfaces with corresponding hardness not only increase wear resistance, but also corrosion protection.

Lösung:
Chemisch Nickel

In order to be able to weld aluminium components, a defined starting position must first be established. The natural oxide layer of aluminium disrupts automated processes due to inhomogeneity. Defined conversion layers remove the natural oxide layer and replace it with a defined passivation. Thus, there are constantly defined starting positions for safe welded joints. With our processes, which have been verified by the automotive industry, we ensure the quality and safety of your production.

Ever more complex technologies and high-precision components require increasing technical cleanliness, which can be guaranteed by industrial parts cleaning.
