Title:
METHOD FOR MANUFACTURING METAL MEMBER HAVING GEOMETRIC STRUCTURE SUCH AS THIN WALL OR THIN GROOVE
Document Type and Number:
WIPO Patent Application WO/2015/096685
Kind Code:
A1
Abstract:
A method for manufacturing a metal member having a geometric structure such as a thin wall or a thin groove. A wax mould with a thin wall structure and a thin groove structure is manufactured by alternately injecting and segment carving two wax-based materials having different properties. Gel casting technology is then used to inject a slurry of a filler metal powder into the wax mould, thereby manufacturing a green body. The green body is then dried by a vacuum freeze-drying method. Finally, the green body is sintered by microwave sintering technology. The present method solves the problems that a green body is prone to cracking during a drying process, and prone to cracking and warping during a sintering process.
