Title (EN) METHOD OF AND ARRANGEMENT FOR MANUFACTURING A PLASTIC DIAPHRAGM FOR AN ELECTROACOUSTIC TRANSDUCER
(FR) PROCEDE ET AGENCEMENT PERMETTANT DE FABRIQUER UN DIAPHRAGME EN PLASTIQUE DESTINE A UN TRANSDUCTEUR ELECTROACOUSTIQUE
Abstract: front page image
(EN)An arrangement (1) for and a method of manufacturing a plastic diaphragm (2) use a deep-drawing station (20) which has a deep-drawing die (33) of a sintered material, air present between the front surface (34) of the deep-drawing die (33) and the basic foil (10) which faces this front surface (34) is extracted through the deep-drawing die (33) via the particle-free interstices formed in the sintered material between the particles (60) coalesced by sintering.
(FR)Agencement (1) et procédé permettant de fabriquer un diaphragme en plastique (2), qui font appel à un poste d'emboutissage profond (20) comportant un outil d'emboutissage profond (33) constitué d'un matériau fritté. L'air présent entre la surface frontale (34) dudit outil (33) et la feuille de base (10) tournée vers ladite surface frontale (34) est extrait à travers l'outil (33) via les interstices exempts de particules formés dans ledit matériau fritté, entre les particules (60) coalescées par le frittage.
