Abstract
Provided is a method for producing a compressed body of a powder capable of improving a hardness while suppressing a decrease in production efficiency of the compressed body of the powder. A compressed body 14 of a powder is compression molded by compressing a powder supplied into die holes 18 by a lower punch 31 and an upper punch 32. In the compression molding, a first compression and a second compression following the first compression are performed. In the first compression, the compression is performed at a first compression speed, and in the second compression, the compression is performed at a second compression speed that is lower than the first compression speed.
Claims4
A method for producing a compressed body of a powder having a solid form obtained by compression molding a powder, the method comprising:
- a first compression step of compressing the powder at a first compression speed;
- and
- a second compression step of compressing the compressed body of the powder compressed in the first compression step at a second compression speed that is lower than the first compression speed until the compressed body of the powder has a final thickness in a predetermined compression state corresponding to a target thickness of the compressed body of the powder from a state of being compressed in the first compression step.
