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.

CERTESS® SD Titanium Boron Nitride

CERTESS ® N Chromium Nitride Coating

CERTESS SD is an excellent coating
for die-casting applications.

CERTESS SD TiBN Titanium Boron Nitride coating which is exceptionally hard at 3500 HV, is typically deposited in the range of 1 to 5 μm.

CERTESS SD coatings provide temperature resistance up to 800°C. Like most HEF PVD coatings, Certess SD is chemically inert. Processing temperature is at a minimum 300°C.

CERTESS SD is most advantageous for die-casting mold applications to counter soldering, heat-checking and wear issues. It can also be used for applications that require an exceptionally hard surface for abrasive wear resistance.
