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 workpiece.
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.

Great article! We’ve been using shot blasting machines in our facility for years, and I can’t stress enough how much they’ve improved our surface preparation process. The results are always consistent, and upgrading to an automatic shot blasting machine has really cut down our production time.
