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

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.
