Flame Spray Gun
About Our Product Flame Spray Gun for Metal Coating and Surface Repair
A Flame Spray Gun is a thermal spraying tool used to melt wire or powder material and apply it as a coating onto a metal surface. It's the equipment behind zinc metalizing, corrosion protection coatings, and the repair of worn or damaged machine parts, without heating the base metal enough to warp or weaken it.
Vands Engineering Solutions manufactures and supplies flame spray guns for coating and surface repair work across India. As one of the established Flame Spray Gun Manufacturers in India, we build ours to give operators steady, controllable output, since an inconsistent flame or feed rate shows up directly in coating quality.
What Is a Flame Spray Gun?
A flame spray gun uses a combustion flame, usually oxygen and acetylene, LPG, or propane, to melt a coating material fed into the gun as wire or powder. Once melted, the material is atomized with compressed air and sprayed onto the surface, where it solidifies almost immediately as a coating.
This process is often called a "cold process," even though it uses a flame, because the base metal stays relatively cool during application. That's what makes it useful for repair work and coating parts that can't handle heavy heat input without distorting or losing their properties. Wire flame spray guns work well on both ferrous and non-ferrous metals, and powder flame spray guns handle materials that are harder to feed in wire form, like ceramics and certain metal alloys.
Vands Engineering Solutions Top Benefits of Using a Flame Spray Gun
Protects and Restores Surfaces
1. Applies corrosion-resistant coatings like zinc and aluminium onto steel structures
2. Repairs worn or undersized machine parts by building material back up
3. Extends the working life of components that face wear, rust, or oxidation

3. Extends the working life of components that face wear, rust, or oxidation
Low Heat Input to the Base Metal
1. Keeps the substrate at a fairly low temperature while coating happens
2. Avoids the distortion and metallurgical changes that high-heat processes tend to cause
3. Works well on parts that need to keep their original dimensions and properties

Frequently Asked Questions
It’s used to apply a metal or ceramic coating onto a surface for corrosion protection, wear resistance, or repair. Common uses include zinc metalizing on steel structures, rebuilding worn machine parts, and applying protective coatings on equipment exposed to rust or high wear in industrial settings.
The gun melts a wire or powder feedstock using a combustion flame, usually oxygen mixed with acetylene, propane, or LPG. Once melted, the material is atomized with compressed air and sprayed onto the surface, where it cools and solidifies quickly to form a bonded coating.
Generally yes, since the process keeps the base metal at a relatively low temperature compared to welding or other high-heat coating methods. This is often called a cold process, and it’s one of the main reasons flame spraying gets chosen for repair work on precision or heat-sensitive components.
Most equipment of this kind runs on oxygen combined with acetylene, though propane or LPG are also used depending on the coating material and what’s available on site. Acetylene generally burns hotter, which suits metals with a higher melting point, while propane or LPG can work for lower-melting materials.
Flame spraying uses a combustion flame to melt the coating material, while arc spraying uses an electric arc, and HVOF uses a high-velocity combustion process at much higher pressure. Flame spray equipment is generally simpler and more affordable, though HVOF and arc spray can offer denser, harder coatings for specific applications.
