FIELD: technological processes.
SUBSTANCE: device includes take-down matrix with external conical surface that is contained into cartridge coupled with it along conical surface, puncheon and boost section, which is coaxially joined with matrix and serves as guide for puncheon. Internal diameter of boost section corresponds to internal diameter of matrix, and puncheon diameter is less than diameter of boost section by minimum value that provides possibility of free-flying operation of puncheon in boost section and matrix. Length of opening in matrix is more than total length of puncheon and height of pressed material installed in matrix, and angle of matrix conical surface is not less than friction angle of materials, from which matrix and cartridge are manufactured.
EFFECT: provides pressures of impact molding that are higher than puncheon material strength.
