A DIE LUBRICANT COMPRISING A HIGHER-MELTING AND A LOWER-MELTING LUBRICANTS |
摘要 |
A method for producing a high density formed product from an iron-based powder composition wherein the iron-based powder composition is filled in a mold having a lubricating agent adhered to its surface through electrification and then formed by pressing the powder composition at a predetermined forming temperature, characterized in that the lubricating agent comprises a lubricant having a melting point higher than the forming temperature in an amount of 0.5 to 80 mass % and a lubricant having a melting point equal to or lower than the forming temperature in a residual amount; an iron-based powder composition which contains an iron-based powder, a lubricating agent for powder forming and graphite, characterized in that the lubricating agent comprises a lubricant having a melting point higher than the forming temperature in an amount of 10 to 75 mass % and a lubricant having a melting point equal to or lower than the forming temperature in a residual amount and the composition contains the graphite in an amount of 0.5 mass % or less based on the total amount of the composition; and a method for producing a sintered compact comprising sintering the formed product. The method can be employed for producing a formed product having a high density in one pressure forming operation.
