摘要:
Process for the production of a component, in which metal or ceramic powder (6) is applied under centrifugal force to the inner wall of a gas-permeable mold (13), which is under reduced pressure and is located in a reduced-pressure vessel (10), and precompacted, after which the mold (13) is removed from the vessel (10) and sintered. The mold (13) consists of a heap of ceramic grains with an organic binder having high strength between room temperature and a temperature just below the sintering temperature, in order to support the powder (6) to be sintered to give the component. When sintering starts, the binder evaporates or burns away, as a result of which the mold (13) substantially loses its supporting action for the component. Binder: aminolic, phenolic, furan resin.
