Abstract
952,130. Moulding plastics articles. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 20, 1962 [Dec. 22, 1961], No. 46004/61. Heading B5A. Articles of thermoplastic sheet material are formed by clamping the sheet 1 between two chambers formed by hinged mould halves 4 and 5, heating the sheet to a formable temperature by a variable electric heater 7, and conforming the thus-softened sheet to a shaping die 6 by first evacuating both chambers and then re-admitting air at a regulated rate into the upper chamber. The heater is then switched off, the article allowed to cool and then removed from the mould.
