We offer hot platens, hydraulic platen press, hot platen press etc., which is used for pressing laminated boards that includes a seal cover assembly for keeping the internal process chamber airtight. The seal cover assembly is fixed in an airtight manner to a cylinder plate located below the platens, through which the pressure cylinders extend in an airtight manner. The upper end of the cover assembly is in sliding airtight contact with the tensile strength members of the press. The sliding contact prevents elongation of the tensile members under pressing force, or vacuum forces on the cover assembly, from causing distortion or breakage. |
