PURPOSE:To permit seamless forming by a method wherein polymeric liquid rubber is made to stand up on the sealing surface of a material to be formed and the composite form is formed by curing the rubber with a covering die removed after curing. CONSTITUTION:The polymeric liquid rubber, as the material of a gasket layer, is made to stand up in the sealing surface 2 of the form 1 to be formed and the rubber 3 is cured by a heating means or the covering die 5, thereafter, the covering die 5 is removed to form the compound form. Accordingly, the gasket layer on the sealing surface is pressed by the covering die and the rubber is cured so as to meet the configuration of a groove formed on the covering die, therefore, smooth and seamless forming may be effected and the sealing property of the form may be improved. |
