Components of a MIM Debinding System Employing Supercritical Fluids

Presented on June 19, 2006

The MPIF/APMI 2006 International Conference on Powder Metallurgy & Particulate Materials

The traditional debinding of metal injection molded parts employs harsh chemicals which are under extreme environmental scrutiny (VOC emissions), takes an inordinate period of time, and/or limits the size of the molded piece. As a consequence of these limitations, efforts have moved to newer technologies to do primary debinding. Moving supercritical fluid debinding from a laboratory phenomena to a commercially viable production process has been achieved.

This paper will describe the components of a supercritical debinding system and its operation. Attention will be given to temperature and pressure considerations, specific supercritical gases and liquids, debinding completion measurement and integration into the current MIM process. Data will be presented highlighting a variety of supercritical debinding procedures.
