Title (EN) POLYMER FABRICATION METHODS
(FR) PROCÉDÉS DE FABRICATION DE POLYMÈRE
Abstract:
(EN) There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.
(FR) La présente invention concerne un procédé de fabrication de polymère permettant de former des formes tridimensionnelles à partir d'une ébauche de polymère en feuille (10) par usinage d'une ou plusieurs rainures allongées rentrantes qui forment une partie d'épaisseur réduite (25) permettant à l'ébauche d'être pliée et ayant des bords en opposition (12) au niveau de sa surface, pliage de l'ébauche autour de la ou des rainures de manière à former une ou plusieurs parties de forme tridimensionnelle, la partie rentrante de la rainure formant une chambre allongée (21) adjacente à la partie d'épaisseur réduite et qui s'ouvre à travers un espace allongé (20) entre les bords en opposition, soudage à l'air chaud des bords opposés au travers de l'espace au moyen d'une une tige de remplissage (22), puis chauffage de la partie d'épaisseur réduite à une température de thermoreformage choisie par l'intermédiaire de la chambre.
