Abstract
A first die is filled with a mixed powder including a lubricant. A first pressure is applied to the mixed powder to form a mixed powder intermediate compressed body having a density ratio of 85 to 96%, provided that the maximum density of the mixed powder intermediate compressed body that can be molded by applying the first pressure is 100%. The mixed powder intermediate compressed body is heated to the melting point of the lubricant powder. The mixed powder intermediate compressed body is placed in a second die that is pre-heated to the melting point. A second pressure is applied to the mixed powder intermediate compressed body in the second die to form a high-density mixed powder final compressed body.
