ABSTRACT:
A shaping mold for the production of ultra-thin shaped rubber articles, has a main body which is dipped into a latex liquid so as to make the latex adhered to the surface of the main body. The adhered latex is heat-dried to form an ultra-thin shaped rubber article over the surface. The mold is such that at least the surface of its main body is made of an amorphous carbon and that its bottom part is fitted with electrifying electrodes and has therebetween a heating area to be heated by resistance heating due to its electrification. The same shaping mold from its dipping step through the inspecting step of inspecting the shaped article as adhered to the surface of the mold. In the heat-drying step of the method, the shaped article as adhered to the surface of the shaping mold is heated and dried from the inside of the mold with preventing as much as possible formation of pin holes in the shaped article.
