(FR) PISTON DE COULÉE SOUS PRESSION, ET APPAREIL DE COULÉE SOUS PRESSION INCORPORANT CE DERNIER
Abstract: front page image
(EN) A piston of a die-casting apparatus comprises: a piston head fabricated of a first material; an elongate, inner carrier coupled to the piston head; a generally annular body seated on the carrier adjacent the piston head; and a wear ring disposed on the piston head, the wear ring being fabricated of a second material. The first material has a higher toughness and a lower hardness than the second material.
(FR) L'invention concerne un piston d'un appareil de coulée sous pression comprenant : une tête de piston fabriquée à partir d'un premier matériau ; un support interne allongé accouplé à la tête de piston ; un corps généralement annulaire supporté sur le support adjacent à la tête de piston ; et une bague d'usure disposée sur la tête de piston, la bague d'usure étant fabriquée à partir d'un second matériau. Le premier matériau présente une plus grande résistance et une dureté inférieure à celles du second matériau.
