Powder forming is one of the key technologies for making high valued sintered products with low cost. And powder sintering process gives us various applications not only in the mechanical parts but also in forming mold, grinding stone etc.... This paper reviews the researches and developments which were conducted in the past 30 years by the author at Institute of Industrial Science, University of Tokyo. Author's achievements includes normal powder forming (powder forging, slip casting, CNC press), sintered mold with fine pattern surface(porous mold, powder spray mold, rapid tooling), sintering of cast iron powder (powder forging of decarbonized cast iron, cast iron bond diamond grinding wheel), fiber metallurgy, high conductive metal/polymer composite and magnetic powder polishing. Many of these new processes are now used in the actual production.
