Thermal Spray HVAF Guns and Torches

High velocitiy oxygen fuel and high velocity air fuel

Kermetico AK – Universal HVAF Machines to Spray a Variety of Metals and Carbides: from MCrAlY and Super Stainless to Cr₃C₂-NiCr and WCCoCr

Kermetico thermal spray equipment. AK HVAF machines work reliably with LPG fuels, such as propane, propane-butane, propylene and MAPP-gas as well as with methane and natural gas. 

Our HVAF machine sprays metals and carbides at optimal temperature, not overheating it. That is how we are spraying bulk-like gas and liquid impermeable wear and corrosion resistant coatings.

The Kermetico AK HVAF machine family includes:

AK7 – a high-power gun for thermal spray of large parts
AK6 – a tungsten carbide gun to spray a balanced mix of parts
AK5 – a gun to spray smaller parts, thin walls, and complex surfaces
AK5-ID – a compact gun to spray internal surfaces 200 mm (8″) and larger
AK-ID – an 80 mm (3.15”) and larger internal diameter spray gun
AK-IDR – a rotating ID gun to spray bores 100 mm (4”) and larger
AK-HH – a manual gun for on-site work

You can also add our Specialized guns to spray functional metal coatings:

SL – a specialized gun for spraying low melting point metals
SP – a dedicated gun for the most efficient precious metal’s deposition
STi – a specialized gun for the deposition of titanium and Ti-alloy coatings

Our AK thermal spray equipment consists of one or more spray guns, a control console with an operator tablet, a powder feeder, a vaporizer and a set of cables and hoses. Each AK system can run several guns. Custom control systems to run multiple guns simultaneously are available upon request.



You can visit our R&D center in Benicia to meet our designers and see our high velocity equipment in action, or check in our distributor’s showroom and job shop in Beijing, China.

We provide thermal spray coating services for customers around the San Francisco Bay Area in California, USA.
