The Ejector Sleeve is a vital plastic injection mold component,akin to the ejector pin, but uniquely designed to reach deeper recesses within plasticparts. Unlike the standard ejector pin, the sleeve is specially crafted forareas with a central hole, such as deeper bosses. Without the use of an ejectorsleeve, these intricate regions cannot be demolded effectively, riskingpotential damage.
