Widest range of off-the-shelf Ejector Sleeves in the industry.
To expand its offering of Ejector Sleeves, Progressive has added treatments for greaseless applications and extended its standard size range for very large injection molds.
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 Ken Rumore, R&D Manager at Progressive. “Unlike PVD processes such as diamond-like coatings (DLC), black nitride penetrates the steel’s substrate and won’t chip, flake, or peel.”
In addition, Progressive has added over 300 new sizes to its range of H-13 Ejector Sleeves. Where U.S. standards end at 14” lengths, Progressive now offers off-the shelf sizes from 15” to 18”, along with new Thin Wall Sleeves and Sleeve Extensions added.
“Whether it’s small, tight-tolerance medical tooling, or huge molds for automotive and appliances applications, mold builders now have the convenience of new standards, and molders benefit from a heat treatment that penetrates the substrate,” said Glenn Starkey, Progressive’s president.
