Method for forming molding or gasket

Abstract

Abstract PURPOSE:To easily form a molding, which is excellent in decorativeness and has a complicated shape, by a method wherein synthetic resin is formed at the peripheral part of a plate glass, which is protected by protective materials. CONSTITUTION:A plate glass 3 is located between a top force 1 and a bottom force 2. The non-molding-forming surfaces 7 and 8 of the plate glass 3 are protected by protective material 9 before its arrangement within the forces. The forces contact through the protective material 9 with the plate glass 3. The interior of the forces surrounded by the inner surface 10 of the top force 1, the inner surface 11 of the bottom force 2 and the molding-forming surfaces 4, 5 and 6 of the plate glass serves as a cavity space 12. By the reaction injection molding method, raw synthetic resin material is poured through a pourer provided in the parting line 13 of the top and the bottom forces in the space 12 in order to form a molding 17. The protective material prevent the surfaces of the plate glass from being stained within the forces and are peeled off the surfaces of the plate glass after the plate glass, on which the molding is formed, is removed from the forces.
