The Difference Between Solid Die and Hollow Die Solid Die The solid die is relatively simple, as long as the split hole is designed, the aluminum handle is squeezed out of the flat flag hole to form a cross section after mixing. 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. The upper die is generally used to guide flow and position the hollow part of the hollow profile. The lower mold is the outer surface working belt and empty knife.   Most of the non-hollow profiles use solid dies. Generally speaking, there is only one mold inc…
