Black Nitride

Unmatched Performance

Black Nitride products from Progressive are proven to perform in medical cleanroom molding environments, cosmetic / appearance product production, harsh conditions such as die casting, and beyond.

Black Nitride (BN) is diffused .003”-.005” into the component, and is not an additive process that can wear off and end up in your parts, like DLC and other surface coatings. 

“Progressive's greaseless components are a gamechanger for Intertech.”

~ Jim Kepler, President, Intertech Plastics

“Progressive's Black Nitride Core Pins outlast all other 5 to 1. We trust these pins to perform in the harshest conditions.”

~ Dan Sheridan, Twin City Die Castings

New Greaseless ejector Sleeves

To expand its offering of Ejector Sleeves, Progressive has added treatments for greaseless applications.

Black Nitride Ejector Sleeves have a precision honed lubricious surface that does not require grease in cleanroom applications, and a high hardness (66-70 HRC) that is suited for harsh conditions such as with die casting.

“When the BN Series Sleeves are combined with Progressive’s Through-Hard Ejector Pins, the dimensional specifications provide the industry’s closest combined precision fit and tolerance between pin and sleeve,” states Glenn Starkey, Progressive’s President. “Unlike PVD processes such as diamond-like coatings (DLC), black nitride penetrates the steel’s substrate and won’t chip, flake, or peel.”


Case Study: Twin City Die Castings Co.

PROBLEM: Die soldering during casting process was degrading core pin surfaces, which required cleaning three to four times per shift, and
replacement every month.

SOLUTION: Switch to black nitride custom core pins from Progressive Components.

RESULTS: Cleaning was reduced, replacement intervals extended five times thanks to greater longevity gained from using black nitride products.
