Title (EN) METHOD FOR MANUFACTURING A HOLLOW GLASS PUNCH FOR PIECE MOLDING
(FR) PROCEDE DE FABRICATION D"UN POINCON DE MOULAGE DE PIECES EN VERRE CREUX
Abstract: front page image
(EN)A compact layer (3) of material is formed by thermal projection on a support piece (1) of which at least the surface portion is made of a material having the property of preventing adhesion of this layer (3) on said support (1) and on the adjacent portion (4) of a piece (2) acting as a base for the punch and the support piece (1) is separated from the projected layer (3) by maintaining the integrity, on the one hand of the assembly formed by the projected layer (3) and the piece (2) acting as a base for the punch, and on the other hand, of the support piece (1). The punch thus obtained is comprised of a hollow body with thin walls having a high mechanical strength.
(FR)On forme, par projection thermique, une couche compacte (3) de matiere sur une piece de support (1) dont au moins la partie superficielle est en une matiere ayant la propriete d"empecher l"adhesion de cette couche (3) sur ce support (1) et sur la partie adjacente (4) d"une piece (2) servant de base pour le poincon et l"on separe la piece de support (1) de la couche projetee (3) en maintenant l"integrite, d"une part de l"ensemble constitue par la couche projetee (3) et la piece (2) servant de base pour le poincon, et, d"autre part, de la piece de support (1). Le poincon ainsi obtenu est constitue par un corps creux a parois minces, ayant une resistance mecanique elevee.
