Abstract
Process and device for the extrusion-moulding of hollow bodies made of a thermoplastic, comprising the extrusion of a tubular parison, its deposition via the use of a robot arm in a preforming device which takes it into a lower part of a mold in which the parison is blow-molded in order to produce the hollow body. Certain steps of the process may be carried out in parallel. This process and this device are very suitable for producing hollow bodies of complex three-dimensional geometry with a high productivity.
