Apparatus for molding permits a fluent molding material to be flowed into a mold cavity for shaping into a configuration defined by the mold walls. A master controller controls the transfer of heat with respect to the molding material, to control the temperature of the molding material in a predetermined way. A sensor measures the temperature of the molding material flowed into the cavity and produces feedback signals, which are compared to reference signals indicative of a desired molding material temperature. The apparatus generates a further control signal, which is applied to control the variables of the molding operation, including the temperature of the molding material and the flow rate.
