The PP 40 features an individual pressure force regulation in the range of 0 to 40 t. The PP 40 combines the advantage of a small benchtop model with high press forces, which are built automatically in up to three steps, ensuring that even difficult materials are pressed perfectly.

The steel ring or aluminium cup is inserted in the pressing tool of the PP 40 and filled with the sample material via a hopper. The complete slide is then pushed beneath the pressure plate and the pressing is started.
During pressure build-up the density of the powder increases. The maximum pressure force must be held over a certain period of time to allow full development of the interparticulate adhesive forces thus guaranteeing maximum stability. Pressing in up to three steps with e.g. increasing pressure force results in stable pellets.
