Process modeling offers a fairly simple means of determining the effect of the key parameters of the material being pressed and the working fluid on the rate of pressure rise in the press-container system. The rate of pressure buildup in the container is the higher the smaller the compressibility loss coefficient of the part and the initial volume of working fluid in the container. In the initial stage the rate of pressure rise is smaller for parts of large volume, but toward the end of the densification process practically identical rates of pressure rise are obtained with parts of different initial volumes.
