Abstract

PROBLEM TO BE SOLVED: To suppress an installation space to half or less of conventional one and to freely alter extending or shortening of a vulcanizing time by largely reducing operating (power) cost of a facility investment and a press required for ensuring predetermined production amount. SOLUTION: In this pressurizing and heating unit 1, rubber material is injected in a mold set in an injection unit at each time, and a plurality of moldings 2 after molding are sequentially stuck in series in order of the injections in the unit 1 provided out of or in the injection unit. In this case, pressure is applied to the injected rubber material by utilizing own weights of the moldings 2 and applied pressure from the exterior. Vulcanizations of the rubbers in the moldings 2 are promoted and progressed by heating and heat insulating the stuck moldings 2. Each time of the injection of the rubber material in the moldings 2, the molding 2 of longer vulcanization lapse time is removed from a plurality of the moldings 2 part in which the moldings 2 are stuck in series.
