Abstract (en)
A machine presses and consolidates flowing solids, especially powdered solids. It has shaping pressing dies which are novel in that the forming surfaces at least have a diamond-like, amorphous carbon layer. Preferably the thickness is 1-10 mu m. The dies are the tablet plungers (1-4) of a tablet making machine. The outer surface (6) of the plunger (3) can also be coated by the material. The head of the plunger (1) and optionally also the shaft (2) itself, are coated in this manner.
Abstract (de)
Die Vorrichtung zum Verpressen von fließfähigen Feststoffen besteht grundsätzlich aus Preßwerkzeugen mit formgebenden Oberflächen. Dabei sind zumindest die formgebenden Oberflächen mit einer diamantähnlichen, amorphen Kohlenstoffschicht versehen. Insbesondere bestehen die Preßwerkzeuge aus Tablettenstempeln (1, 2, 3, 4), die in einer Tablettiermaschine Verwendung finden. Die Schichtdicke der amorphen Kohlenstoffschicht liegt vorzugsweise im Bereich von 1 bis 10 µm.
