DID YOU KNOW?
Progressive's Black Nitride products are proven to perform in medical cleanroom molding environments, cosmetic / appearance product production, harsh conditions such as die casting, and more.
"Progressive's Black Nitride Core Pins outlast all others 5 to 1. We trust these pins to perform in the harshest conditions."Dan Sheridan, Twin City Die Castings
Black Nitride (BN) is diffused .003"-.005" into the component. It is not an additive process that can wear off and end up in your parts like DLC and other surface coatings.
This treatment is especially advantageous with Ejector Sleeves, where the center Core Pin (our Through-Hard Ejector Pin) also is Black Nitrided. As an option, the Core Pin can be supplied with the black surface removed by diamond polishing.
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.
Progressive’s Ken Rumore recently described this further in a portion of a recent webinar on components for medical molds which can be found HERE. In addition, Darrell Witham describes all of our Ejector Pin and Sleeve treatment and coating options in a 3-minute video found HERE.
