Abstract
A method for shaping a preform made from thermoplastic material, and a facility for implementing the method, comprising the following steps: a) providing a preform made from thermoplastic material having a surface; b) supplying thermal energy to the preform by radiation in such a way as to make it ductile; and c) shaping the ductile preform inside a forming mould. Step b) further involves simultaneously spraying a gaseous fluid onto the surface of the preform in order to preserve the surface.

A method of forming a preform made of thermoplastic material, comprising the following steps:
- a) providing a preform made of thermoplastic material having a surface;
- b) providing heat energy by radiation to said preform such as to make it ductile;
- and,
- c) forming said ductile preform inside a forming die;
- wherein, at step a), a thermoplastic composite material is provided, and
- at step b), a gaseous fluid is simultaneously projected at the surface of said preform in order to protect said surface.
A facility for forming a preform made of thermoplastic material, comprising, firstly, a radiation heating enclosure for receiving a preform made of thermoplastic material such as to be able to provide heat energy by radiation to said preform to make it ductile, and, secondly, a forming die located downstream of said heating enclosure in order to be able to form said ductile preform;
- further comprising a gaseous fluid projecting device installed inside said radiation heating enclosure in order to be able to project said gaseous fluid at the surface of said preform, when said preform receives heat energy by radiation, such as to protect the surface of said preform.
