Abstract (en)
[origin: WO9704944A2] The invention relates to a process for making containers (2) from a raw material (5), especially polycarbonate, in which the raw material (5) is plasticised in an extruder (4) and injected through a heating channel (7) into an injection moulding tool (9) for a pre-moulding (14). The pre-moulding (14) is then inserted into a shaping tool (24) and expanded to the desired volume by feeding a pressurising medium into its interior. The container (2) is then removed from the shaping tool (24). A core (15) and a cavity (11) of the injection moulding tool (9) are kept at different temperatures above 70 DEG C in order to produce the pre-moulding (14). The cavity (11) is kept at a higher temperature than the core (15).
