There are things that seem to exist forever. There are also things that wear out under high strain! These elements must do what they are intended for every day. We contribute to things staying that way. Read more...

Flame spraying

Increased productivity and performance of technical equipment and machines increase the requirements of segments or elements. Therefore the highly burdened surfaces at risk are protected by thermal spraying. Read more...

Base coats

By our maintenance work that we carry out on defect and worn machine parts in consultation with our customers, we provide the opportunity to limit production disruptions and standstill to Read more...

Applications

We coat worn surfaces with suitable materials in the required coating strengths. The special features of metal spraying find versatile applications in many industrial sectors. Read more...

Material selection

We use standardised and certified spray wires and spray powder for metal spraying. These wires and powders are sprayed with various, tested flame spraying pistols with thermal and kinetic energy in various methods. Read more...

Metal spraying technology

Metal spraying method is a collective term for the various thermal spraying methods. Metal spraying is based on the interaction between kinetic and thermal energy.

Metal spraying was developed in the early 20th century and originally included spraying of molten metal particles. Thermal spraying made it possible to apply metal on correctly prepared elements, without reaching the heat input necessary with welding or melting.

Aluminium

Aluminium flame spraying is a variant of flame spraying according to DIN EN 657 / DIN EN ISO 14919 for all elements which are not suitable for spray galvanising or fire galvanising. chromed or nitrated elements are unsuitable for example.

Bronze

Bronze coating is a variant of flame spraying according to DIN EN 657/DIN EN ISO 14919 for all elements suitable for bronze coating chromed or nitrated elements are unsuitable for example.

Ceramic

We spray on ceramic coatings with plasma ceramic spraying and powder flame ceramic spraying. There are different ceramic spray agents for ceramic coating.

Molybdenum

Molybdenum coatings have a hardness of 60-66HRc depending on the coating method used and are perfect for the manufacture of wear-resistant coatings.

NiCrBSi

NiCrBSi alloys and their composition according to DIN EN 1274 and DIN EN ISO 14920 with subsequent fusion have a particularly good resistance to wear and corrosion.

Copper

Spray copper plating was further developed and based on new findings became a fixture of very good electric conductive coatings and improved electric conductivity of elements made from poor or non-conductive agents.

Wolfram

Wolfram/Tungsten carbide with hardness of up to 2300HV represents an excellent base for a wear protection coating for long duration. The coating is carried out through flame spraying.
