MOLD COMPONENTS – INCH Support Pillars and Stop Pins Support Pillars S.A.E. 1040 Steel Pillar height (C dimension) is finished flat and parallel. Support pillars should be used liberally since they greatly increase the capacity of the mold to support the projected area of the cavities, runner and sprue. By providing additional support, they prevent deflection of the mold. The absolute necessity of using support pillars is demonstrated by using standard strength of materials formulas. For example, an 11 7 ⁄ 8 x 15" mold base without support pillars and with a maximum permissible load on the support plate, will permit 14 square inches of cavity area without deflecting enough to cause flash. The use of one row of support pillars on center will quadruple this permissible cavity area to 56 square inches. Two rows will give nine times the area or 126 square inches. Please refer to the drawings below.

Two rows of support pillars increase the permissible cavity area 9 times LOAD Support Pillars Support pillars are universally adaptable for cap screw, threaded locating pin, or socket set screw applications. Order pillars from chart at left and required “fasteners” as listed below. Cap Screw (S.H.C.S.) Applications 3 / 8 -16 or 5 / 8 -11 socket head cap screws can be ordered in length required.
