摘要：
The present invention relates to a press of pressure cell type, a tray for use in a press of pressure cell type and a method. The tray comprises a tray frame, which defines a space for arranging a forming tool and/or a work-piece. Prestressing means are arranged on the external surface of the tray frame and induce a compressing prestress which acts in planes parallel to the plane of the tray. The tray frame presents a curvature along its entire circumference.
