Title:
COMPRESSION MOLDING METHOD FOR POWDER AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/001868
Kind Code:
A1
Abstract:
A magnetostrictive actuator (52), as an impact force generating means, is inserted between at least one of the upper and lower rams (2, 5) of a powder molding press and a punch (3). After the compression by a predetermined static pressure, the compression by the impact force is performed to reduce the internal stress. If the downward pressure of the upper ram (2) is released after the compression by the static pressure and the upper ram (2) is dropped by the weight thereof, the molding time can be further reduced.
