SINTERING DEVICE, AND METHOD OF MANUFACTURING SINTERED BODY

摘要

PROBLEM TO BE SOLVED: To ensure the degree of shape freedom of an obtained sintered body and to enhance the compactness of the formed sintered body by forming a pressurizing part narrowed in the cross-sectional area in a hollow interior of a cylinder to apply predetermined pressure to powder passing through the pressurizing part. SOLUTION: This sintering device is provided with a hollow cylinder having a powder inlet 1 and and an outlet 8, and a pressure piston 3 for pressing the powder 2 in the hollow interior of the cylinder 4. The outlet 8 is in an open state, and the hollow interior of the cylinder 4 is formed with the pressurizing part 7 narrowed in the cross-sectional area to the cross-sectional area of the hollow interior of the cylinder 4, halfway from the upper reaches side formed with the powder inlet 1 toward the lower reaches side formed with the outlet 8, and a heating device 6 is installed in a position corresponding to the pressurizing part 7 of the cylinder 4.
