Abstract

The invention is concerned with a compression molding device (1) with a tool (3) generating at least a part of the work-piece geometry. At least one pressure measuring means (5) and/or at least one pressure space (4) is located directly below the work-piece associated surface (3.3) of the tool (3). Besides this, the work piece (3) selectively exhibits at least one first part (3.1) which is a tool template generating the shape of the work piece and a second part (3.2) forming the base body, wherein a measuring strip (6) is provided between the tool template (3.1) and the base body (3.2). As an optional refinement, the measuring strip (6) is an elastic intermediate layer with a smaller modulus of elasticity than the base body (3.2).
