Improved efficiency of deposition work between a protection trimming and a clip seat of an automobile is provided with an automatic deposition machine having wire heating elements ( and ), a first connection member ( ) connected to one end of the wire heating elements ( and ), a movement mechanism for moving the first connection member ( ), a second connection member ( ) that can be connected to the other end side of the wire heating elements ( ) and ( ) and a bending jig ( ) for overlapping the clip seat the member for the protection trimming. The dip seat and the protection trimming are interconnected, to the rear face of the protection trimming via the wire state heating elements ( and ), the retainer member ( ) for retaining the said overlapped clip seats, and the power source for carrying the electric current between the said first connection member and the said second connection member. In addition, the wire heating element is designed with a pipe structure. The cooling gas is passed inside the pipe structured heating element after the deposition between the clip seat and the protection trimming by the electrification.

Automatic deposition machine

A molded product is thermally bonded mutually with another molded product by disposing the resistance heating element (20) to the bonding face of product molded with the thermoplastic resin, making the bonding electrode (10) contact the resistance heating element (20) and by impressing the voltage for its heat generation. The heat generation temperature of the resistance heating element (20) at the voltage impressed portion (21) is suppressed to the level lower than the fusion temperature of resin by blowing the cooling gas toward the voltage impressed portion (21) from a vent hole (11) provided on the bonding electrode (10).
