ABSTRACT:
A method for molding is disclosed in which a fluent molding material is flowed into a cavity of a mold, which is then shaped into a configuration defined by the mold. Control signals which are applied by operating a master controller to control the transfer of heat with respect to the molding material, in order to predeterminately control the temperature of the molding material as it flows into and is retained within the mold. The temperature of the molding material flowed into the cavity is sensed, and feedback signals are generated relating to the sensed temperature. The feedback signals are compared to reference signals indicative of a desired molding material temperature and a further control signal is generated which is applied to control the variables of the molding operation, including the temperature of the molding material.
