Liquid Nitriding

Liquid nitriding is a subcritical surface enhancement process with one of the longest track records of success of any 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 thin 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.
