METHOD FOR HOT-FORMING A THERMOPLASTIC MATERIAL AND IMPLEMENTATION FACILITY

摘要

The invention concerns a method for shaping a preform made from thermoplastic material, and a facility for implementing said method. The method comprises the following steps: a) providing a preform (15) made from thermoplastic material having a surface (30); b) supplying thermal energy to said preform by radiation (15) in such a way as to make it ductile; and, c) shaping said ductile preform (15) inside a forming mould (26). Moreover, step b) involves simultaneously spraying a gaseous fluid onto the surface (30) of said preform (15) in order to preserve said surface.
