Abstract

Thermoplastic mouldings that are open on one side, e.g. cups and dishes, are produced by heating thermoplastic sheet; stamping out a complete plate; hermetically clamping the plate in a zone lying within the cut line, and moulding the plate, either mechanically and/or by a pneumatic pressure difference applied to the two sides of the plate. Exactly dimensioned prods., including the edges are formed with low material use.
