发明名称 MOLDING METHOD
摘要 PURPOSE:To obtain a high-quality molded item at good yield in manufacture by a method wherein a material to be molded is arranged between a mold and an elastic body, the position corresponding to the recess of the mold of which is constituting so as not to protrude beyond its peripheral part, and then pressure is applied to the elastic body. CONSTITUTION:An elastic body 3 is placed on a material to be molded 4, which is set on a mold 1. In the above-mentioned state, because the surface of the elastic body 3 is flat, the material to be molded 4 and the elastic body 3 come into uniform contact with each other regardless of the position at the recess 2 of the mold 1 and the remaining position excluding the position at the recess 2. Accordingly, after that, when a downward force is applied to the elastic body 3 by means of a pressing means, the force given by the pressing means acts nearly uniformly on the underside of the elastic body 3 at the start of the application of the force. Consequently, the material to be molded 4 is pressed at the periphery of the recess 2 by the top surface of the mold 1 and the elastic body 3. Thus, the material to be molded 4 is given deforming pressure by the elastic body 3. As a result, after the predetermined period of time, a projection corresponding to the recess 2 is formed on the material to be molded 4.
