Thermal Spray Gun

A thermal spray gun is a spraying gun in which the molten liquid of abrasive is sprayed on the subject. This lays down a coating onto the surface of the subject. As the name suggests Thermal spray gun means a substance thermally sprayed on the subject.

There are many types of thermal spray gun:

Metallizing Gun : 

In this gun, the metallization of metal takes place with the help of heat. This heat melts the metal wire into the liquid. Then it is sprayed on the surface of the subject. On part of abrasive, we can take rod, wire, powder to fed inside the gun.

Flame Spray Gun :

Flame spraying usually requires only low-cost equipment. It is suitable for single-piece and series production and can be used in both stationary and mobile configurations. The main applications are corrosion and wear protection. The use of wire or powder depends on the material and the application rate. Zinc, aluminum, and molybdenum are mostly sprayed as wire. Most metal and hard-alloys are applied as a powder.

Arc Spray Gun :

In this gun, two arcs of wire are generating with the help of electric supply anode and cathode. These wire when touched generate the spark which leads to heat to the two-wire. Melts down and sprayed over the subject. It is also called as Electric Spray Gun or Twin Arc Spray Gun.

HVOF Gun :

HVOF stands for High-Velocity Oxy-Fuel. HVOF Gun is a thermal spray system utilizing the combustion of gases or liquid. Combustion gases such as hydrogen and liquid fuel such as kerosene are used. Fuel and oxygen combine and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure required for coating.

Zinc Spray Gun :

In this type of gun different abrasive can be used for spraying on the subject. Like commonly anti-corrosive abrasive is used for protecting the surface from the corrosion. Mainly Zinc spray gun, Aluminum spray gun is used.
