Title (EN) METHOD OF FORMING FUEL TANK WITH BAFFLE PLATES
(FR) PROCEDE DE FORMATION DE RESERVOIRS DE COMBUSTIBLE MUNIS DE CHICANES
Abstract:
(EN) A fuel tank characterized in that two preformed baffle plates are mounted to a blow pin, this blow pin is inserted into a molten parison made of thermoplastic resin, closing of a split mold and supply of pressure fluid are performed in this state, and the baffle plates are welded into the tank simultaneously with the forming of the tank. As the two baffle plates are provided in the fuel tank simultaneously with the forming of the tank, the fuel tank having no thin thickness wall portions can be manufactured.
(FR) On réalise un réservoir de combustible en montant deux chicanes préformées sur un poinçon de soufflage en introduisant le poinçon de soufflage dans une paraison fondue en résine thermoplastique, en fermant un moule à coins et en appliquant un fluide sous pression dans cet état, et en soudant les chicanes dans le réservoir en même temps que l'on forme ce dernier, de manière à produire un réservoir dont les parois ne présentent pas des parties de faible épaisseur.
