Electric wirespray
Electric spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc is generated between them.

The heat from this arc melts the incoming wire, which is then entrained in an air jet from the gun. This entrained molten feedstock is then deposited onto a substrate with the help of compressed air in order to form a coating. With electrical wire spraying, coatings can be applied quickly and at low cost.
The high heat content and conductivity of the plasma flame and the very high gas and transport speed of the molten particles result in a strong, well adhered, homogeneous and clean sprayed layer.

And traction coatings.
More flame spray
Plasma spray
The high heat level and conductivity of the plasma flame, in combination with the very high gas- and transport velocity of the molten particles result in optimal condtions for very strong adhesion, uniformity and purity of the sprayed layer.
Autogenous powderspray
With autogenous powderspray, coatings have a homogeneous structure. These hot sprayed layers are well resistant to line, point and impact loads.
Autogenous wire spray
For corrosion protection, repairs or size corrections. The spray layers applied in this way are more or less impact or shock resistant. The structure of the layer is always micro-porous. This gives the ability to hold oil and thus self-lubricating properties are obtained.
What is flame spraying
Flame spray is a unique and practical technique to apply a coating to almost any kind of metal and non-metal surfaces. This coating improves the basic material properties such as hardness, abrasion, scratch and corrosion resistance.
HVOF flamespray
HVOF flamespray forms a coating with a high density and a high bonding value. The HVOF flamespray principle is based on a transfer of thermal and, in particular, kinetic energy from the spray particles of the substrate.
