<p>Process for manufacturing sintered products, includes: mixing a sinterable powder material, a liquid carrier and a gelling agent to form a mix, the gelling agent having a gelling temperature below which the mix is substantially rigid and a sol temperature above which the mix is substantially fluid; introducing the mix into a forming mould having a filter suitable for passing at least the liquid carrier and trapping at least the sinterable powder material; applying a pressure in the mould with the mix having a temperature substantially higher than the gelling temperature and is substantially fluid, the pressure being suitable for allowing the liquid carrier to come out at least partially from the mould through the filter; lowering the temperature of the mix in the mould below the gelling temperature to obtain a substantially rigid semi-finished product; sintering the semi-finished product to obtain the sintered product.</p> |
