Soft Core Pins
(60) JBF National soft core-core pins come manufactured from hot forged and annealed steel and feature a ground finish. To ensure the highest quality, JBF National soft core pins are laser inspected throughout the entire manufacturing process. Soft core pin through hardness is 30/35 R/C. /Asset/Soft-Core-Pins---1.jpg Hard Core Pins
(107) JBF National hard core-core pins come manufactured from hot forged and annealed steel, and feature a ground finish. To ensure the highest quality, JBF National hard core pins are laser inspected throughout the entire manufacturing process. Hard core pin through hardness is 50/55 RC. Please see component diagram below. /Asset/Hard-Core-Pins---1.jpg Straight Style Nitride Ejector Pins
(161) JBF National nitride straight style ejector pins are manufactured using certified H-13 die steel and come completely nitride processed. These ejector pins feature a head that is both hot forged and annealed, in addition to being ground finished under the head for maximum seating. Our pins have a 45 R/C core hardness, 68/74 R/C surface hardness and are laser inspected throughout the entire manufacturing process. /Asset/Straight-Style-Nitride-Ejector-Pins---1.jpg Straight Style Metric Nitride Ejector Pins
(235) JBF National nitride ejector pins are manufactured using certified H-13 die steel and come completely nitride processed. These ejector pins feature a head that is both hot forged and annealed, in addition to being ground finished under the head for maximum seating. Our ejector pins have a 45 R/C core hardness, 68/74 R/C surface hardness and are laser inspected throughout the entire manufacturing process. /Asset/Straight-Style-Metric-Nitride-Ejector-Pins.png Conical Pins
(125) JBF National conical ejector pins(countersunk head ejector pins) are manufactured using the highest quality certified H-13 die steel. These pins have a 45 R/C core hardness, 68/74 R/C surface hardness, carry a g6 tolerance, and are laser inspected throughout the entire manufacturing process. Due to their smaller head when compared to typical cylindrical head ejector pins, conical pins are great for applications with head dimension issues. Please see component diagram below. /Asset/Conical-Pins---1.png
Shoulder Style Nitride Ejector Pins
(54) JBF National nitride shoulder style ejector pins are manufactured using certified H-13 die steel and come completely nitride processed. These ejector pins feature a head that is both hot forged and annealed, in addition to being ground finished under the head for maximum seating. Our ejector pins have a 45 R/C core hardness, 68/74 R/C surface hardness and are laser inspected throughout the entire manufacturing process. /Asset/Shoulder-Style-Nitride-Ejector-Pins---1.jpg Mold Leader Pins
(105) JBF National mold leader pins are manufactured from the highest quality steel and feature a nickel-chromium finish. These mold leader pins also feature a groove-less design to allow for optimum alignment between mold halves. /Asset/Mold-Leader-Pins.jpg Steel Shoulder Bushings
(60) JBF National steel shoulder bushings feature the highest quality case hardened steel with a HRC58-62 hardness rating, as well as a ground-in lead. /Asset/Steel-Shoulder-Bushings.jpg
Ejector Sleeves
(103) JBF National ejector sleeves are manufactured using certified H-13 die steel and come completely bright nitride processed both inside and out. These ejector sleeves can both be used as housing for the ejector pin or as the actual ejector pin itself. These ejector sleeves feature a ground finish under the sleeve head to ensure the best seating possible. Surface Hardness: HRC65-74 Core Hardness: HRC 40 ±5. /Asset/Ejector-Sleeves---1.jpg B Series Sprue Bushings
