cation of multilayer ceramic processing, it is important for most substrate designs that the punch surface and the pressure plate surface be parallel to each other. However, with certain other substrate designs one of the surfaces, usually the pressure plate, must be allowed to flex to form slightly concave or convex laminates depending on the quantity of internal metallurgy. The parallelism or flexing results in a constant green density which translates to uniform shrinkage during sintering.
