Description
Summary:-20 kHz ultrasonic vibration compacting system with 15-mm-diameter upper and lower vibration punches and a radial vibration die, and 20 kHz vibration compacting system using 5-mm-diameter upper and lower vibration punches are studied. Compacting of metal, alloy and ceramics powder is important process for powder metallurgy which is used for producing small and precise mechanical parts and required for various industry fields including electronics. Some complex metal alloy, amorphous alloy and fine ceramic powder such as zirconium are impossible to compact using only static pressure. Various powder are compacted with larger density and more uniform distribution compared that without vibration.
