EXPULSEURS DE MATRICE POUR EMBOUTISSAGES AU MOYEN DE PRESSION.

摘要

The ejector has a female part, and a male part (1) situated inside a cavity (2) existing in a central zone of a shoulder (2a). Small independent elements (4) are adapted to be incorporated or inserted in a hollow zone created in the central zone, where the elements are made of polyurethane. The cavity forms graphics by pressing the male and female parts installed adequately in an opposed manner. A shoulder or lug (5) absorbs a pressure exerted by a press on a metallic or acrylic plate e.g. license plate.
