Flame Spray Gun

Flame spraying uses flame spray gun for coating. A thermal spray process variation in which the controlled explosion of a mixture of fuel gas, oxygen, and the powdered coating material is utilized to melt and propel the material to the work piece.

A flame spray gun involves blowing a plastic powder through a flame that partially melts the powder and fuses it because it contacts the substrate. It includes low-velocity thermal spray powder, red, and wire flame processes, and high-velocity processes.

The part's surface is preheated with the flame. The standard approach is to coat only a few square meters at a time, so the temperature can be controlled. The flame is then adjusted. When the coating is completed, the powder is shut off and therefore the coating is post-heated with the flame. Flame spraying is especially useful for coating products with surface areas overlarge for heating.
