INCH PINS, SLEEVES, BLADES Thin Wall Ejector Sleeves and Sleeve Extensions
Thin Wall Sleeves DME Standard Thin Wall Sleeves reduce cost by replacing the need to buy expensive custom ejector sleeves or to machine steps in standard sleeves.
Ejector sleeve applications Fig. A shows a typical Ejector Sleeve application for plastics molding or die casting where the sleeve is used to eject the piece part. Fig. B shows an application where the sleeve serves as a bushing for the ejector pin. This allows replacement without machining if wear occurs. This practice is also desirable where the ejector pin is located between cavity inserts. Using a sleeve as a bushing provides a full bearing diameter for the pin.
•
Precision made of superior quality thermal shock resisting hotwork die steel Hot-forged heads provide uniform grain flow, higher tensile strength Outside diameter nitrided to 65-74 HRC hardness and finished to minimize wear Centerless ground and polished outer diameter Inside bearing diameter is 30-35 HRC hardness and finished honed Lead-in taper designed to allow interference-free entry of the ejector pin into the sleeve
