Abstract

moulds for mfg. hull or deck components for boats by in situ expansion of a moulding material where the moulds comprises two opposing cavity shells made of laminated polyester resin backed by metal supports. Means are provided for sealing the boundary between the male and female tools by a strip of flexible plastic or elastomeric material located in a channel around the border of the cavity. PRef. the metallic reinforcement comprises pairs of metal ribs clamped at intervals to opposite edges of the mould shells. Suitable for mfg. mouldings with expansion pressures up to 5 kg/cm2 e.g. requiring a clamping force of 45 tonnes for a hull 3.3 m long.
