Abstract

A mixture of a foamable thermoplastic material and a blowing agent in a mixing and pressing device (1) is brought to a temperature and pressure at which temperature and at which pressure the mixture is liquid. The mixture is then forced via an outflow opening (2) connected directly to one or more filling openings (8), lying in the same plane, of a female mould (5) into the female mould cavity (7). After the filling, the female mould (5) and the outflow opening (2) are pushed towards one another, the female mould (5) being provided with surfaces which cut off the material flow on displacement of the female mould. It is thereby achieved that the object produced has no sprue and that virtually no blowing agent can escape out of the outflow opening (2).
