Support Pillars & Stop Pins
Support pillars should be used liberally since they greatly increase the capacity of the die to support the projected area of the cavities, runner and sprue. By providing additional support, they prevent deflection of the die. The absolute necessity of using support pillars is demonstrated by using standard strength of materials formulas. For example, an 117/8 x 15" die 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.
