  • Method and apparatus for compressing particulate matter
    Patent number: 8679387
    Abstract: A compression molding apparatus for particulate matter comprising a magnetostrictive actuator functioning as an impact force applying means arranged at least between an upper ram or a lower ram and an upper punch or a lower punch. Particulate matter is compressed by a static pressure, and then an impact force is applied to the particulate matter to reduce internal stress. After compressing the particulate matter by the static pressure, the upper ram is allowed to fall gravitationally to shorten a molding time.
