Abstract

1,003,036. Vacuum-moulding hollow articles. DUNLOP RUBBER CO. Ltd. Aug. 23, 1962 [Sept. 1, 1961], No. 31459/61. Heading B5A. A sheet 1 of thermoplastic material is vacuum moulded by heating the sheet 1 by a heater 11 and simultaneously progressively applying a vacuum so that the sheet, as it softens, is drawn into contact with the former 6. The sheet 1 may be moulded on to a female former 6 (Fig. 1) or may be moulded first on to a female former 6 and then on to a male former 13 (Fig. 3). The sheet 1 may be preheated to remove residual stresses and the formers 6, 13 may also be heated. The process if suitable for many thermoplastic materials, e.g. polystyrene, polyvinylidene chloride and p.v.c. but is particularly suitable for shaping polyethylene or polypropylene containing 0À5% to 30% of a paraffin wax for use as a mould for shaping polyurethane foam. Specification 1,003,034 is referred to.
