Three-plate extension bushings can save material, reduce cycle time and help prevent runner hang-ups in 3-plate molds. Designed for use with T-Series 3-Plate Mold Bases, 3-Plate Extension Bushings reduce sprue length to aid in the ejection of the runner from the mold. Made from AISI 4140 steel that's been hardened to 28-32 HRC, 3-Plate Extension Bushings permit easier, faster installation than competitive bushings. All grinding for the final fit is on flat surfaces with no I.D. or O.D. angles to grind.
