<p>PURPOSE:To remarkably improve the workability of bagging by performing adhesion of a seal material under pressure by providing energy in an assembly prepd. by adhering a bagging film for high temp. molding for a thermoplastic resin composite with the seal material. CONSTITUTION:In an assembly 1 wherein the outer edge part of a heat-resistant bagging film 2 is adhered with a seal material 3 and the outer surface of the seal material 3 is covered with a releasable seal 4, when a heat-resistant seal material 3 which exhibits weak adhesiveness at room temp. and is hardly adhered with the bagging film 2 for high temp. molding, good adhesion is made possible by providing energy under the condition wherein both parts 2 and 3 are brought into contact with each other and under pressure. As the device for providing energy, a heating device based on heat transfer, impulse, high frequency, ultrasonic, electromagnetic induction, infrared etc., is used and an ultrasonic welding device is preferably used. Leakage hardly occurs thereby at bagging and workability for bagging is improved.</p> |
