Metal Spray Gun
Metal spray gun
A Metal spray gun is used for the thermal coating process which uses a single wire, cord, and powder as a raw material for coating. This feed material is melted in an oxygen fuel gas flame or with the help of an electric arc. This molten metal is atomized by compressed air and impinges on the surface of the substrate.
For melting the coating material both a flame spray gun and electric arc process are used. In the electric arc process of a metal spray gun, the arc is generated between the cathode and anode. In metalizing gun coating material having opposite polarity is used.
In the electric arc spray gun process, two methods are used to forward the coating wire. One is an air drive and the other is an electric arc drive. In the air drive, compressed air is used to forward the wire and in the electric drive, a motor is used to forward the wire connected to the electric panel.
In the flame type compressed air is used with oxygen and acetylene gas to melting the coating material. Thermal spray gun LPG gas is also used sometimes at the place of acetylene with oxygen.
Features of Metal Spray Gun
- Very efficient and reliable
- High performance
- Easily utilized
- Cost-effective
Thermal spray gun rollers are used to pass the wire in a forward direction for melting. Compressed air is used to impinge the molten metal on the surface of the substrate with high velocity.
Metal spray guns are very much useful in various kinds of industrial, automobile, and mechanical utilities. Metalizing Gun provides excellent coating facilities while giving minimum heat input to the base metal. A metalizing gun is very much helpful in corrosion control coating.
A metal spray gun provides a thick coating to prevent the surface of the substrate from rust and oxidation. The coating process increases the life of the substrate. A metalizing gun provides an equally thick layer of coating.
