ABSTRACT:
In a method for producing shaped synthetic members, one begins with superficially plasticized synthetic granulated material in manner known per se. This is sintered to form a preform in a first operation in a preliminary chamber. The preform is then extruded by way of a narrow nozzle into a moulding cavity, the nozzle cross section being so narrow that on the way between the preliminary chamber and the moulding cavity, the individual granular particles must be deformed mechanically. The moulding cavity is then filled by one or more thin strands, which consist of solid, but mechanically deformed and superficially plasticized granulated particles.
