Abstract
A control system for controlling a molding machine used for exothermic curing senses the rate of change of the temperature of the material in the mold. When the rate of change of temperature has first exceeded and then fallen below a predetermined reference level, it is determined that the exothermic curing reaction has been completed, and the mold is opened after a predetermined delay.
