Abstract

Provided herein is an apparatus of manufacturing a molding material that can significantly reduce the frequency of replacement of a bottom member without increasing the drainage time longer. A bottom member () is constituted of two layers of wire meshes including an annular dutch-woven wire mesh (A) made of stainless steel and an annular plain-woven wire mesh made of stainless steel. The two layers of wire meshes are secured to each other by sintering. A support plate () made of stainless steel is disposed between the bottom member () and a lower hollow compression mold (). The support plate () has a plurality of through holes () formed therein, and is configured to support the bottom member ().
