Abstract: PURPOSE:To mold a porous ceramic pipe filled uniformly with a kneaded material without generation of products having a nonuniform wall thickness by vibrating a mold set perpendicularly on a vibrator, introducing the kneaded material consisting of aggregate particles and binders into the mold, and molding said material. CONSTITUTION:A mold 2 with a core 3 set therein is perpendicularly secured on a vibrator 1 and, while the mold 2 is being vibrated by the vibrator 1, a kneaded material 4 consisting of aggregate particles and binders is introduced from an introducing vessel 10 into the mold 2 through a belt conveyer 11.
