<p>A heating-type vacuum press device which has a small vacuum isolation chamber in which pressing is performed under vacuum without damage to seal packing, while heating. A lower fixed frame and an upper movement frame constitute a wall portion of the isolation chamber. <??>A gas-tight sliding mechanism ensures gas-tightness between the lower fixed frame and the upper movement frame. Thereby, the isolation chamber is formed in a space defined by the lower fixed frame, the upper movement frame, a base and a fitting plate. The lower fixed frame surrounds a receiving table equipped with a heater for a workpiece, and is arranged on the base such that the lower fixed frame is spaced from the receiving table. The upper movement frame is hanged from the fitting plate such that the upper movement frame is spaced from a pressing plate equipped with a heater, and surrounds the pressing plate. <??>The isolation chamber is sucked to vacuum, and a workpiece on the receiving plate is pressed under heating and vacuum at a high temperature with a low thrusting force by descending the pressing plate. <??>The present apparatus is suitable for bonding multi-functional laminated films having high heat-resistant temperature. <IMAGE></p> |
