machine is by means of the high frequency oscillation
of the sonic waves to contact directly with the workpieces
to be welded to transmit the oscillation and use the
pressure to increase the temperatire of the workpieces
to reach to melting, then stop oscillation and hold
the set pressure to harden the workpieces to achieve
the welding effect. Use ultrasonic cutter can prevent the burr edge of cut cloth.
machine takes small volume and easy to work at anywhere.
