Workpieces of a synthetic plastics material are heated to enable further lding thereof to be effected. Heating is effected by infra-red radiators and, in order to ensure that localized overheating is avoided, the surface of the workpiece which is exposed to radiation is cooled during the heating process.

Method for heating plastics materials

An apparatus and method for heating parisons or other thermoplastic compots preparatory to forming the component to a different shape, as by blow molding. The parisons are heated by conveying them past an elongated infra-red radiator in spaced relation to the radiator. A concave reflector is provided for each parison, the reflector being movable with the parison in fixed relation thereto. The parison is located at the focal location of the reflector so that heat from the radiator bypassing the parison is reflected back to the parison.
