Provided herein is a system for manufacturing a core of a vacuum insulation panel, the system comprising: a plurality of molding cast parts disposed along one direction, and providing a molding space for core material to be supplied and press-molded; a plurality of raw material suppliers distanced from one another, and supplying core material to the molding space; a press-molder disposed between the raw material suppliers, and receiving the molding cast part where the core material is supplied through the raw material supplier, and pressing the molding space; and a carrier transferring the molding cast part after the core material is supplied by the raw material supplier and the molding space is press-molded by the press-molder.

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.
