Method for manufacturing blanks from a synthetic plastics material includes mould cavity defined between a mandrel and an outer mould. A retractable sleeve is slidably mounted on the mandrel and is displaceable within the cavity at a rate which depends on the rate at which the plastics material is injected into the cavity.

Method for manufacturing plastics blanks

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.
