Common Misconceptions About Ultrasonic Welding Machines

Common Misconceptions About Ultrasonic Welding Machines

Ultrasonic welding machines have become widely used in various industries such as product packaging, 

cutting, riveting, embossing, and punching, making them indispensable equipment. As a result, a variety

 of ultrasonic welding machines with different functions have emerged.Different application fields, 

usage methods, and equipment requirements lead to significant differences in consumer usage.

 Let's explain these misconceptions!

Misconception 1: Ultrasonic Output Power

The magnitude of ultrasonic output power is determined by the diameter and thickness of the piezoelectric 

ceramic chip, as well as the material and design process. Once the transducer is completed, the power supply

is also set. 

Measuring output energy is a complex process. This doesn't mean that a larger transducer or more 

powertransistors in the circuit will result in greater output energy. It requires a highly sophisticated amplitude

 measurement instrument to measure its amplitude. 

Misleading information from some salespeople has led to misconceptions among consumers because they 

oversimplify the concept of ultrasonic power.The consumed electrical energy does not directly reflect the size 

of the ultrasonic output power. For example,low longitudinal energy generation with high current consumption

 indicates low equipment efficiency, and high reactive power is appropriate.

Misconception 2: Selection of Ultrasonic Welding Machines

Factors such as output power usage, oscillation frequency, and amplitude range should be considered based on 

various factors like the material of the workpiece, the area of the welding area, the presence of electronic 

components in the workpiece, and whether it needs to be sealed. Assuming that higher power is always better 

is also a misconception.

If you have limited knowledge of ultrasonics, consult engineering and technical personnel from reputable 

ultrasonic manufacturers. If possible, visit the manufacturer for direct communication and avoid blindly 

following misleading information from informal ultrasonic salespersons.

Currently, there is a mixture of enterprises producing related equipment, many of which are small workshops

 with makeshift circuits and a lack of understanding of the working principles.

Counterfeit equipment has the following fatal flaws: first, the quality of purchased raw materials cannot be

 guaranteed; second, the core technology of the production process is not mastered. The equipment often

 exhibits instability during medium and high-power operations, leading to low product qualification rates. 

Equipment failure is also a possibility."
