Non-standard/Custom Mold Base Features
Support Pillars
Support Pillars 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. Support Pillars are universally adaptable for cap screw, threaded locating pin, or socket set screw application.
