The principal of SX-5000 HVOF equipment is: the mixture gas of oxygen and fuel gas is sent to the burning area of spray gun exit under high pressure. Then the burning gas is accelerated to form a supersonic flame with the help of peripheral compressed air. The spray powder is sent into burning flame and make a functional coating.
SX-5000 consists of spray gun, powder feeding machine, control system, heat-exchanger system and pipeline system. It’s a compact equipment with the traits of easy-operating, stable working performance, low fuel consumption and high-quality coating.
Control system
Spray gun
Spray gun with manual and machine fixed way of operation. Gas needed: oxygen and propane (C3H8), weight: 2kg. velocity of spray particles: ≥450m/s. It can work a long time stably.

Powder feeding machine
The SX-5000 powder feeding machine is used to store spray powder and send them to burning flames according to technological requirements. The feeding gas is nitrogen, which pulverizes the powder and sends the pulverized particles along with the gas to spray gun. You can regulate the feeding velocity by the localizer on the regulating control panel.
