<p>A device comprising as forming elements a matrix (1) with a guiding channel (2) and a plunger (3) all of them being executed as splitted collets provided with elastically fixed and radially folded back lobes (4, 5, 6). The lobes (4) of the matrix (1) and the lobes (6) of the plunger (3) form in their closed position the forming working surface (7, 8). The lobes (5) of the guiding channel (2) are directly contacting the lateral surface of the matrix (1). The device can be used in different fields of technology where spherical articles moulded made of oxidative powdered materials are used.</p> |
