PVC plastic film, ultrasonic welding machine welding, welding can.
When the lines are increased, the effect of welding is completely different from that of the high frequency machines. The specific performance is pale, the fastness is not enough, the lines are not good, and the holes will appear.
Ultrasonic welding of PVC film is possible in principle, but because the principle of ultrasonic wave is to produce heat by friction, it is necessary to do dentate pattern on the die to increase friction, otherwise it does not generate heat.
PVC film fused traditional method is the use of high frequency welding machine, if you must do something to subvert the traditional innovation, it is rather difficult to estimate, ultrasonic machine in the welding of PVC films when there is no way out with the same high frequency welding welding effect.
