1. A vulcanizing apparatus comprising:

  • a. a first platen assembly including1. a first frame member; and

    2. first means forming a first platen surface, said first means being fixed to said first frame member,b. a second platen assembly including1. a second frame member,2. second means forming a second platen surface, said second means being associated with said second platen assembly for movement toward and away from said second frame member in a direction generally transverse to said second platen surface,3. a flexible diaphragm associated with said second frame member, said diaphragm being spaced therefrom and being substantially coextensive with said second platen surface, said diaphragm having a periphery,4. third means affixing the periphery of said diaphragm to said second frame member, said diaphragm and said second frame member being so constructed as to form a fluid chamber between a first surface of said diaphragm and said second frame member,5. heat exchange means for cooling said second platen surface, said heat exchange means having a heat transfer surface that is substantially coextensive with said second platen surface,6. heating means forming a heat transfer surface substantially coextensive with said second platen surface,7. insulating means forming a layer of insulation interposed between said diaphragm and said second means, said heating means and said heat exchange means being sandwiched between said insulating means and said second means,c. fourth means removably coupling said first and second platen assemblies so as to orient said first and second platens surfaces in generally parallel, spaced, mutually opposing relationship, andd. fifth means associated with said second platen assembly for admitting and exhausting fluid from said chamber for increasing and decreasing the fluid pressure in said chamber to move said diaphragm relative to said second frame member and to thereby move said second platen surface toward and away from said platen surface.
