Abstract

Improved drying, binder evaporation, and sintering processes which may be used in conjunction with specialized sintering tools to provide for the geometrically stable sintering of large, complex, metal injection molded preform parts or flowbodies. The improved process includes a three-stage drying process, a single stage binder evaporation process, and a two-stage sintering process.
