A process for the production of open containers, in particular sanitaerartikeln such as bath tubs, shower tubs, produce washstands or the like.

摘要

A container e.g. sanitary ware is reinforced by inverting a container inner wall portion 3 over a die 2 which closely abuts the inner surface of the container portion. A layer of fibre material 4 is placed on the outer surface of the container portion 3 either before or after the container portion is inverted over the die 2. A quantity of curable liquid plastics material 5 is placed on at least one point of the fibre layer and the resulting article is hot pressed between the die and a mould 6 whose moulding surface conforms in shape to the outer surface of the finished container. The quantity of plastics material used is approximately equal in volume to the finished reinforcing layer. The moulding pressure is applied until the reinforcing layer is sufficiently hardened to allow the article to be removed from the die without deformation and the die is heated or cooled by passing a heat transfer medium through tubes 7.
