Pressure stamp mold useful for spark discharge sintering or field-activated sintering, comprises stamp formed by powdered material that is introducible into cavity of matrix for compacting and sintering, and electrically conductive material

摘要

Pressure stamp mold comprises at least one stamp (1) formed by a powdered material that is introducible into a cavity of a matrix for compacting and sintering, and an electrically conductive material, where the pressure stamp mold is connectable to an electrical voltage source, and includes a region having different electrical conductivity. The stamp is formed with at least one region having different electrical conductivity with multiple cavities (1.2) and/or regions having at least two parts (1.4, 1.5) of the stamp containing different materials.
