Two independent thermostats control each platen separately, so you get the exact temperature you need for the top and bottom of your mold. Ideal for the new 0% shrinkage rubbers (such as Castaldo No-Shrink Pink) that demand precise temperature control.  Heavy-duty cast-iron and aluminum construction with 1" diameter pressure screw and heavy guide posts to ensure uniform pressure on mold and perfect alignment of stainless steel platens. On/off toggle switch with pilot light and 2 separate thermostat pilot lights. Accepts both single and double mold frames. Made in USA.
