  • Patent number: 7690906
    Abstract: A rotary powder compression molding machine configured to compression-mold powder filled in a die bore of a die mounted on a turret between a lower end face of an upper punch and an upper end face of a lower punch, is provided including powder lubricant jet means for jetting powder lubricant, the powder lubricant jet means including: jet nozzles, each of which has a concave surface, faces a respective one of end faces of the upper and lower punches at a respective powder lubricant jet position, and is configured to guide the powder lubricant along the concave surface and jet the powder lubricant in substantially one direction; an air stream providing mechanism configured to jet an air stream to adjacent the lower end face of the upper punch for preventing the powder lubricant jetted from the jet nozzles from scattering upwardly; and a charger device configured to charge the powder lubricant electrostatically upon jetting from the jet nozzles.
