Metalizing Gun

Metalizing is a general process of metling metal in molten form to have thermal spray coating process is used for coating metal on product surfaces. The resultant metallic coatings can be used for protective, Anti-corrosive, decorative or functional purposes. These coatings are also known to be long-lasting, effective and highly versatile. 

Three Types of Spraying Techniques:

Electric arc spray
Combustion powder spray
Combustion wire spray

Electric Arc Spray is this process, we utilize two metallic wires that are electrically charged with opposing polarity as the coating feedstock. This will cause them to throw a molten arc between each other. Then injection of inert gas or high velocity air to trigger an atomization of the now-molten material and propel onto the substrate to form the coating. If you opt for the electric arc spray process, we can spray any type of metals which have melting points below 5540°C.
Depending on the equipment being used and the material being applied can provide metallic coatings with either semi-metallurgical bonds or mechanical bonds up to 5000 P-S-I. Distortion will not occur because the substrate is not exposed to high temperature over 120°C.

Combustion Powder Spray is this process, the basic principle of the heat source is the same as wire spray except that powders are fed through a flame and propelled by high velocity oxygen or air onto a substrate. As with the metalizing process, any powdered metal or ceramic having a melting point below 3400°C. Can be sprayed. This process is mainly used for abrasive coatings and spray/fuse hard surfacing.



Combustion Wire Spray is this process, we feed the spray material in wire form into a fuel gas-oxygen flame where it is melted by the heat (temperature up to 3400°C) of that combustion. Compressed air is concentrated around the flame, atomizing the molten material into fine spherical particles and propelling these particles at high velocity onto a the substrate.
We can manipulate the atomization and the melting of metals with different melting points when we control the feeding rate of the wire through the flame. When you opt for this method, we can spray any wire as long as it features a melting point below 3400°C.
