Sažetak
The paper discusses our experiance in design and control of metal flow in weld pocket and hollow dies. Special attention is paid to the weld pocket design used for the production of solid shapes. Weld pockets are now of the great interest since the use of pullers on extrusion presses has been predominant lately. Various types of hollow dies are available for production of hollow sections. The selection of the die type and die geometry is a difficult task for a die designer. Metal low is more complex than in the flat dies. It can be controlled on the several places at the entrance, in the channels and weld chambers, as well as on the exit side of the hollow die.
