Abstract
A method for forming a compact from a powder wherein a forming portionA in a mold bodyis filled with a raw powder and upper and lower punchesare fitted into the forming portionA to form the compact. Prior to filling the forming portionA with the raw powder M, a solution L with a lubricant being uniformly dissolved in a solvent is applied to a peripheral portion of the forming portionA, and then the solution is evaporated, thus forming a crystallized layer B thereon. Thus, the reduction of a force for ejecting the compact is realized, while improving the density of the compact, realizing the stable and successive production of the compact.
