Abstract

PROCEDE DE MOULAGE DE BOUTEILLES EN PLASTIQUE. ON FABRIQUE UNE PARAISON EN MATIERE PLASTIQUE MOULEE PAR INJECTION. LE FOND PLAT A UNE EPAISSEUR INFERIEURE A CELLE DE LA PAROI LATERALE. ON PLACE LA PARAISON DANS UN MOULE D'ETIRAGE POUR SOUFFLAGE ET ON ETIRE PAR SOUFFLAGE LA PARAISON DANS LE MOULE POUR FORMER UNE BOUTEILLE TERMINEE. APPLICATION A LA FABRICATION DES BOUTEILLES EN PLASTIQUE.PLASTIC BOTTLE MOLDING PROCESS. AN INJECTION MOLDED PLASTIC PARAISON IS MANUFACTURED. THE FLAT BOTTOM HAS A THICKNESS LESS THAN THAT OF THE SIDE WALL. THE PARAISON IS PLACED IN A BLOW STRETCH MOLD AND BLOW STRETCH THE PARAISON IN THE MOLD TO FORM A COMPLETED BOTTLE. APPLICATION TO THE MANUFACTURE OF PLASTIC BOTTLES.
