The operation efficiency of the molding of an integral product is improved, and the compression of a material is timed easily, by using silicone rubber having a high elasticity, a high thermal resistance and a high mold releasability. A method of manufacturing an integral compression molded product out of silicone rubber by using upper and lower molds is provided. This method comprises the steps of applying a urethane foam mixture uniformly to an upper surface of horizontally retained silicone rubber, and compressing the resultant material by upper and lower molds for a predetermined period of time. The application of this mixture is carried out by a spraying system so as to obtain a uniform layer thereof. The silicone rubber can also be vacuumsucked to an inner surface of the lower mold. Since silicone rubber is used, the operation efficiency is improved, and the running cost decreases. Moreover, a pressurizing operation can be timed easily, and even a molded product of a deep drawn shape can be manufactured beautifully.
