Abstract
A method directed to manufacturing porous products by supplying a water-in-oil type high internal phase emulsion into mold elements, shaping and polymerizing the emulsion. It is characterized by a moving shaping unit provided with a lower mold element on one side having a smooth mold face furnished with a depressed part and an upper mold element on the other side having a smooth mold face furnished with a corresponding depressed part forming a cavity of a stereoscopic shape together with the depressed part of the lower mold element. Prior to the union of the two mold elements continuously supplying the emulsion into the two mold elements, transferring the shaping unit into a polymerizing device subsequent to the union of the mold elements, and shaping and polymerizing the emulsion therein.
