Our Product / Services
Our offered Product range includes HVOF Coating Service, Aluminium ARC Spray, TWIN WIRE ARC SPRAY PUSH TYPE, High Velocity Oxy Fuel and WIRE COMBUSTION SPRAY.
High Velocity Oxy Fuel(HVOF) devices are a subset of flame spray. There are two distinct differences between conventional flame spray and HVOF. HVOF utilizes confined combustion and an extended nozzle to heat and accelerate the powdered coating material. Typical HVOF devices operate at hypersonic gas velocities, i.e. greater than MACH 5. The extreme velocities provide kinetic energy which help produce coatings that are very dense and very well adhered in the as-sprayed condition.
BENEFITS :-
Low porosity (10000 psi)
Uniform repeatability
