Abstract
It is necessary to reduce the debinding time in powder injection molding process. Therefore, recently, there are methods such as ANAX process of removing the binders and the solvent debinding which can solve the problems mentioned above becomes to get much attention. Here discussed solvent debinding of injection molded Fe-36%Ni with use of polyvinylbuthyral as organic binder. The all organic binders of the componud dissolved into the solvent in this process, although the all ones of the compound could not be always dissolved into the solvent on conventional solvent de-binding process. In this process, the sintered bodys scarely containing carbon were produced under these conditions ;(1) extraction binder volume was at least 30vol% after the solvent debinding process, and (2) after solvent debinding process, the optimum maximun temperature on thermal debinding process was 350°C in air.
