Abstract
A method for manufacturing hollow and other metal products of irregular shape provides metal powder and binding agent, and the two are feed-mixed and heated to a plastic state. The feed-mix is injected in a mold cavity of a first injection mold to form a first blank, and injected in a mold cavity of a second injection mold to form a second blank. The first blank and the second blank are welded together to form a built-up blank which is degreased to remove the binding agent therein. The degreased built-up blank is sintered to obtain the metal product of irregular shape.
