Like aluminum flat strips, aluminum rods, some special-shaped materials, etc. Hollow Die Hollow dies are generally combined by two combined molds, so that the cavity can be formed by splitting the flow through the working belt during extrusion, such as aluminum shells and round tubes.   For ordinary extrusion dies, to produce hollow profiles, a splitter die must be used, which consists of an upper die and a lower die.
