Abstract

The invention concerns a sealing plate, in particular a valve plate, as well as a method for making the same. The sealing plate consists of a metal plate (1) with essentially parallel plate surfaces (4, 5) and with one or more ports (3). It comprises at least one sealing bead (9) formed on at least one of the plate surfaces (4), surrounding at least one of the ports (3). This sealing bead (9) is provided with a pressed, flat sealing surface (10). To form the sealing bead (9), plate metal is upset forming a bead (8) on a plate surface (4) in a first step and the top of this bead (8) is flat pressed in a second step. Preferably, the bead (8) is built-up by free flowing upsetting.
