FIELD: technological processes.
SUBSTANCE: direct extrusion of solid rod and reverse extrusion of hollow rod with external diameter that is equal to diameter of ball pin leg is done. Then bottom is punched in hollow rod and distributed on sphere from the side of punched opening. For final head clamping on sphere matrix is used that does not have connectors in horizontal and vertical planes. At that distribution and clamping is done with internal backpressure.
EFFECT: quality of items is increased.
