PROCESS FOR PRODUCING SHAPED BODIES BY SINTERING
A method for producing a shaped body by sintering including steps of a. providing a starting material containing metal powder and/or ceramic powder, b. forming a green part from the starting material by shaping the starting material if it contains binder material or by introducing a binder material into a powder bed formed from the starting material, c. chemically debinding, and/or debinding by means of a solvent, the green part to obtain a brown part, d. thermally debinding the brown part, e. consolidating the brown part to give the shaped body by sintering. The brown part is treated after step c. and before step d. with a plasticizer that softens the binder material still present in the brown part. Before step d. and after the treatment with the plasticizer, the brown part is subjected to an isostatic pressing operation by contacting with a medium under an elevated pressure.
