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

PVD coatings involve the deposition of thin (2-10 microns; 0.0001" – 0.0004") films on the surface of tools and components.

Engineered Bushings

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

HEF's Operational Capabilities for High Volume Automotive Coatings

HEF has also demonstrated the ability to handle large volumes of automotive parts using specially designed robotics; pre and post-coat surface finishing capability and a robust quality management system, including TS 16949. A combination of high throughput / high productivity PVD equipment & PVD processes; extensive use of robotics and automated product inspection; efficient product handling systems and optimized coating specifications have made it possible for HEF to position PVD coatings as a value-added surface engineering option to enhance the performance of automotive and precision-engineered industrial components.
