PROCESS FOR THE MANUFACTURE OF SINTERED PRODUCTS |
摘要 |
<p>The process for the manufacture of sintered products (5), comprising the steps of: mixing a sinterable powder material (1), a liquid carrier (2) and a gelling agent (3) to form a mix (4) for the manufacture of a sintered product (5), the gelling agent (3) having a gelling temperature below which the mix (4) is substantially rigid and a sol temperature above which the mix (4) is substantially fluid; introducing the mix (4) into a forming mould (6) having filtering means (7) suitable for being crossed at least by the liquid carrier (2) and trapping at least the sinterable powder material (1); applying a pressure in the forming mould (6) with the mix (4) which has a temperature substantially higher than the gelling temperature and is substantially fluid, applying a pressure being suitable for allowing the liquid carrier (2) to come out at least partially from the forming mould (6) through the filtering means (7); lowering the temperature of the mix (4) in the forming mould (6) below the gelling temperature to obtain a substantially rigid semi-finished product (8); sintering the semi-finished product (8) to obtain the sintered product (5).</p> |
