Process for producing injection-moulded sinterings.

摘要

A process for producing an injection-molded sintered product by powder metallurgy is claimed, which comprises injection molding a kneaded product comprising a magnetic powder and a binder, releasing the molded product from the metal mold, and sintering the molding after debindering, wherein the molding is taken out from the metal mold using an electromagnet which exerts an adsorptive force to the molding. The process simplifies the release of the injection-molded products from metal molds and the transfer of the molding to the debindering process; it therefore is suitable for mass production, gives high yield, and has a wide applicability to products regardless of their shape.
