ABSTRACT:
A hollow extrusion device includes a piston for pushing a billet of aluminum alloy through a first molding die placed on an opposite side of the billet. The molding die may comprise any number of cavities, but preferably comprises three cavities. On a side of the first die from which the extruded billet exits, a second die is provided and forms an outer shape of the expansion valve body. Subsequent to passing through the second die, mandrels are provided which form penetrating holes in the extruded, shaped material. One mandrel forms a second path in the expansion valve body, and two other mandrel form two bolt holes in the expansion valve body. The extruded, shaped material is cut to a set length, then further processed.
