Title:
METHOD FOR METAL INJECTION MOLDING
Document Type and Number:
WIPO Patent Application WO/2019/137963
Kind Code:
A1
Abstract:
The invention relates to a method for producing a cast body. The method comprises the steps: producing one or more insert parts; providing the one or more insert parts in a casting mold of an injection molding tool such that a cavity corresponding to the shape of the cast body is formed by the one or more insert parts or by the one or more insert parts together with the casting mold; filling the cavity with a molding compound containing a powder of a sinterable material; producing a green part by solidifying the molding compound; removing an intermediate product, consisting of the green part and the one or more insert parts, from the injection molding tool; removing the one or more insert parts from the intermediate product; debinding the green part; sintering the green part.
