Abstract
1,157,806. Moulding hollow articles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 25 July, 1966 [11 Aug., 1965], No. 34362/65. Heading B5A. Hollow articles are made by coating a male mould member with a thermoplastic composition, heating to fuse the coating, transferring the coating to a female mould member on insertion of the male mould member while it is still plastic, and after cooling, removing the article therefrom. The female mould may have more detailed local features and surface texture than the male mould. The composition may be applied as powder e.g. by fluidized bed. Transfer may be assisted by application of pressure to the coating through the male mould and/or by applying suction through the female mould.
