Sewing-free vamp vacuum high-frequency processing method and device

The invention discloses a sewing-free vamp vacuum high-frequency processing method and device. The method comprises the steps that at first, a thin silica gel sheet having a sealing function covers a to-be-processed vamp formed by a multi-layer vamp material, vacuumizing is carried out, and negative pressure formed by vacuum is utilized for coating and exerting pressure on the to-be-processed vamp; and then a high-frequency electric field is utilized for welding and forming the to-be-processed vamp. The device comprises an upper polar plate and a lower polar plate which are spaced vertically and arranged oppositely to form a working capacitor. The working capacitor is connected with a high-frequency power source to form the high-frequency electric field. The lower polar plate is used for containing the to-be-processed vamp. A vacuum pump communicates with the lower polar plate and is used for vacuumizing the to-be-processed vamp. The method and the device can improve product quality and reduce energy consumpt
