Title:
METHOD AND APPARATUS FOR MANUFACTURING MULTI-MATERIAL POWDER METAL COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2003/013768
Kind Code:
A1
Abstract:
A method and apparatus for forming an object from first (105) and second powder metal (PM) (115) materials are disclosed. The method includes providing first and second surfaces to form a first cavity having a first opening, filling the first cavity with the first PM material (105) through the first opening, and compacting the first PM material (105) by way of a third surface that covers the first opening. The material additionally includes moving the second surface to create a second cavity bounded at least in part by the compacted first PM material (105), filling the second cavity with the second PM material (115) through a second opening, and compacting both the second PM material (115) and the compacted first PM material (105) by way of the third surface that covers both the first opening and the second opening.
