HVCW
MICROJET SYSTEM HVCW High Velocity Wire Spraying
The GMA MICROJET is a New Generation High Velocity Combustion Wire Spray System (HVOFW) which provides supersonic spray velocities, combined with improved heating and melting of the wire particles.
9 Shock Diamonds characteristic of a supersonic flame are visible in the flame. The HVCW technique has great opportunities where near porosity free high quality coatings at the most economical cost is the requirement.
“Recent finds have shown that coating obtained from HVCW technique are similar to or comparable to other High Velocity Spraying Process"
Lower Porosity
High Hardness
High Bond Strength
Excellent Wear Resistance
Good Surface Finish - as sprayed
Thick Coatings (if required)
High Deposition Rate
Fine Finishing Capability
Flow meter Gas flow control
Flash-back arrestors
Safety cooling system
Electric wire feeder Crouzet type or Airmotor
The operating cost of High Velocity combustion wire spray is lowest, compared to other HVOF & Plasma Spray Technique with highest spray rate and quality results.
The system consists of the following main parts:
A complete flame spray installation requires equipment to supply and control compressed air, oxygen, fuel gas and metallizing wire.
AUXILIARY FLAME SPRAY EQUIPMENT
The Wire Reel Stand
The Gas Control Unit & Air Control Unit.
The Hose Kit
The Wire Feed Control Unit (pull)
The Gas Flowmeter
The MICROJET GMA Metal Spray Gun
