As such, when the header plate 100 is coupled to the coupling groove 14 of the mold body 10, the fusion teeth 160 protruding from both sides of the protruding end 140 of the header plate 100 are coupled to the coupling groove. The header plate seating step (ST100) is performed to be seated in close contact with the bottom of the (14).

Subsequently, ultrasonic vibration is generated on both fusion splints 160 of the seated header plate 100 such that the two fusion splints 160 are fused to the bottom of the coupling groove 14. At this time, the first ultrasonic vibration proceeds to the first fusion step (SP200) while proceeding until the lower surface of the curved surface of the secondary fusion fusion 180 formed between the two fusion fusion 160 is in close contact with the bottom of the coupling groove (14) To perform.

At this time, the two fusion splicing 160 is formed to protrude sharply on the left and right sides of the protruding end 140, so that the maximum welding strength can be obtained at the minimum pressing force with respect to energy due to ultrasonic vibration.

Subsequently, in the state in which the central auxiliary fusion meat 180 is in close contact with the bottom of the coupling groove 14 through the first fusion process, ultrasonic vibration is generated in the auxiliary fusion meat 180 and the fusion meat 160 on both sides thereof. So that the protruding end 140 is inserted between the bent ends 22 of the terminals opposite to both sides, so that both lower end surfaces of the upper panel 120 are in close contact with the end surfaces of the bent ends 22 of the both terminals 20. do.

That is, the protruding end 140 and the panel 120 are lowered while the both fusion splicing 160 and the auxiliary fusion splicing 180 are fused to the bottom of the coupling groove by ultrasonic vibration, and the protruding end 140 is lowered. ) Is tightly received between the bent ends 22 of the terminals 20 oppositely coupled to both sides, and both bottom surfaces of the panel 120 are in close contact with the upper ends of the bent ends 22 of the terminals 20. A secondary fusion step (ST300) to completely fix the bent end 22 of 20 is performed.

At this time, the auxiliary fusion splicing to improve the welding strength and to prevent deformation of the coupling groove of the mold body by dispersing the energy of the ultrasonic vibration for the left and right fusion splicing process.

That is, by proceeding the fusion step divided into the primary and the secondary to prevent the deterioration of the fusion strength and deformation inside the coupling groove by the pressing force of the tool horn generated when fusion splicing at one time.

Finally, the two fusion splices 160 and the auxiliary fusion splices 180 are coupled to each other so that both bottom surfaces of the panel 120 are completely in contact with the top surface of the bent end 22 of the terminal by the secondary fusion step.
