Liquid Nitriding

Liquid Nitriding is one of the pioneering processes carried out to improve the surface properties of Steel & cast iron components. It is a case hardening technology.

PVD Coatings

Physical vapour deposition and plasma-assisted chemical vapour deposition (PVD and PACVD) are environmentally-friendly vacuum deposition technologies involving a deposition of material on the surface of the parts to be treated.

Engineered Bushings

HEF bushings are recognized worldwide for their excellent frictional and anti-seizure properties, and ability to withstand high loads.
