Some common problems and opinions of ultrasonic welding machine

 1. How to detect ultrasonic mold frequency matching problem:

The general processing depth of ultrasonic mold design is 1-1.5mm. According to the high-frequency skin effect, the higher the frequency, the higher the temperature, but the smaller the sensing depth. Hardness depends on your workpiece material, 45 steel can generally reach about 50, but more than 50 is easy to crack.

2. The power board of the ultrasonic welding machine is easy to burn out, the reasons and solutions:

The reasons why the power board of the ultrasonic welding machine often burns are: one is short circuit, the other is bad insulation leakage, and the third is the quality problem of the power board. A three-point overhaul of it can be solved.

3. Choose ultrasonic welding machine, is the power the better?

Of course, it is not the greater the power, the better, but according to the size of the welding surface of the plastic products, to determine the need for more power ultrasonic plastic welder! Different products use different power options, small parts can use low power, fragile also use low power welding, such as 35K, for difficult to weld materials or large parts can consider using high power welding. In addition, the quality of the machine regardless of power, high-power machine welding effect more accurate products will be better.

4. What does the delay time of ultrasonic welding machine mean

The delay time of the ultrasonic welding machine refers to the ultrasonic wave emitted after the delay time from the moment the switch is pressed.

5. What is the distance between the ultrasonic mold and the workpiece suitable for ultrasonic mold adjustment?

Generally, the distance between the upper welding die and the workpiece is 75mm. Operation method: Loosen the body locking rocker, turn the lifting handwheel, make the distance between the upper welding die and the workpiece greater than 75mm, pull the locking rocker.
