Ultrasonic welding machine welding problems First, excessive welding
Reason: the input of plastic pieces of energy too much
Solution:
1, lower air pressure
2, to reduce the welding time
3, reduce the amplitude of the number of segments
4, replace the low magnification two pole
Ultrasonic welding machine welding problems Second, insufficient welding
Reason: the input of plastic pieces of energy too little
Solution:
1, increase the pressure
2, extended welding time
3, increase the number of amplitude segments
4, replace the high magnifier two pole
5, the use of higher power models
Ultrasonic welding machine welding problems Third, the welding effect is inconsistent
the reason:
1, injection mold changes
2, the use of hose material or secondary material
3, the proportion of filling changes
Solution:
1, check whether the injection mold wear
2, to improve the use of materials
3, fixed filler ingredients
Ultrasonic welding machine welding problems Fourth, non-welded surface damage
the reason:
1, welding head and plastic contact surface does not match
2, ultrasonic concentration damage
Solution:
1, repair the welding head and the end of the mold so that it coincides with the plastic pieces
2, repair the welding head in the relevant position to avoid empty
Ultrasonic welding machine welding problems 15, plastic parts cracking, shock
the reason:
1, the ultrasonic amplitude is too large
2, plastic pieces of strength is not enough
Solution:
1, select the low magnification two pole
2, reduce the output amplitude
3, plastic plus stiffening or thickening
Ultrasonic welding machine welding problems Six, plastic parts of the surface perforation
the reason:
1, ultrasonic amplitude is not enough, caused by long-term welding
2, ultrasonic concentration damage
Solution:
1, to improve the output amplitude, reduce the welding time, if necessary, replace the larger power models
2, the corresponding position of the welding head to avoid air
3, plastic parts to strengthen the thickness or strengthen the ribs
