FIELD: metallurgy.
SUBSTANCE: press mould for pressing of powder material contains lower puncheon with holes, balls, major and minor disks from plastic material of the same composition, matrix, upper puncheon and additional lower puncheon pre-lubricated with grease lubricant. Major disk is placed on four balls, matrix is installed and minor disk is installed on three balls. On the surface of minor disk there installed is the additional lower puncheon, powder is put into matrix, upper puncheon is introduced into the matrix cavity and pressure is applied.
EFFECT: improving accuracy of measurement of pressure loss for external friction and providing possibility of nanosized powders pressing.
