Abstract
L’invention concerne un procédé de fabrication d’un écran (1) de protection acoustique pour compartiment à moteur de véhicule automobile, ledit écran comprenant une sous couche (4) en mousse surmoulant une coque (3) obtenue par thermoformage d’une feuille à base de polyoléfine dont la face interne a été traitée par décharge électrique pour augmenter sa tension de surface, ladite feuille étant chauffée selon les phases successives suivantes : une phase de préchauffage à température modérée inférieure à la température de fusion de ladite feuille sans dégrader sensiblement la tension de surface de ladite face interne, une phase de chauffage intensif où ladite feuille est brièvement chauffée à température élevée, au moins égale au double de ladite température de fusion exprimée de degrés Celsius, de manière à atteindre la température de ramollissement de ladite feuille sans dégrader de façon excessive ladite tension de surface.
