The invention relates to a method for producing components preferably of a gas turbine, particularly an aircraft engine, by means of powder-metallurgical injection molding. In powder-metallurgical injection molding, a powder metal is first mixed with a binding agent so as to obtain a homogeneous mass, whereupon at least one molded body is produced from the homogeneous mass in an injection molding process, and the or each molded body is subsequently subjected to a debinding process. The or each molded body is then compressed by means of sintering to obtain at least one component having desired geometrical properties. According to the invention, the or each molded body is mounted in at least one holding device during sintering, said holding device also being shrinkable during the sintering process. The invention further relates to a corresponding holding device. |
