Customer Reviews
The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

What is the difference between ultrasonic metal welding machine and ultrasonic plastic welding machine?

 

1. Different working methods

 

The vibration direction of the welding head of the ultrasonic plastic welding machine is perpendicular to the welding position during the welding process, and the vibration direction of the welding head of the ultrasonic metal welding machine is parallel to the welding position during welding. In some special cases, plastic welding can also use parallel directions, such as thinner plastic parts.

 

2. The metal welding machine is used to weld metal and puts forward higher requirements for ultrasonic welding technology; compared with ordinary plastic welding, the requirements for power capacity, power density, stability and automation control are not the same level .

 

1. High-power capacity and stable ultrasonic generator: The first requirement of a stable ultrasonic generator is: automatic frequency tracking. Automatic frequency tracking can ensure that the transducer system can work in resonance. The use of automatic frequency tracking technology, no need to adjust the frequency when changing molds and working, is the basic requirement for metal welding. The equipment with adjustable

inductance and manual frequency adjustment basically cannot meet the requirements.

 

2. High power capacity: Compared with plastic welding machines, a welding machine requires a higher energy density and must have a relatively high power capacity. For example, a 20kHz machine basically requires a power capacity of more than 3000W.

 

3. High-quality welding head: As an industrial application, metal welding inevitably requires a long-life welding head.

 

4. High-quality control system: It has three basic control modes of welding energy, time and height, and a variety of quality control software to meet different needs.

 

5. High-quality transducer: For example, a 20kHz transducer must be able to withstand a load above 3kw for a long time.
