Industry-leading HVOF thermal coating and reclamation

Backed by our state-of-the-art, purpose-built arc spraying and high velocity oxy-fuel (HVOF) facility, our company has a reputation for providing industry best outcomes for companies operating in mining, construction, oil and gas and other heavy industries.

The HVOF process applies very dense, strongly adhered coatings by injecting metal powder into the high pressure gas stream. HMG’s HVOF machine can spray Carbon Chromium Silicon Boron Iron Nickel, Chromium Nickel Molybdenum Silicon Boron Copper, Tungsten Carbide-Nickel, Carbon Chromium Iron and Tungsten Carbide Cobalt Chromium Powders.
HVOF spraying is an alternative for chrome plating because it enables a flexible choice of coating materials for each application. For example, tungsten carbide is up 10 times stronger than traditional hard chrome plating.
The Arc Spraying process melts metallic wires onto the component by an electric arc of compressed air. HMG’s Arc Spray machine can spray nickel aluminium, and a variety of
Arc Spraying is the most versatile of the thermal sprays; it can be used in a very wide range of applications and can be more cost-effective.
