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 !!!

Several points to pay attention to during ultrasonic welding
Latest company news about Several points to pay attention to during ultrasonic welding
  • Out of the ultrasonic welding several misunderstandings: how much oscillating frequency, output power, amplitude range, etc., should be determined according to the wire area of the workpiece, the material, whether the workpiece is airtight, whether it is airtight, whether it is a component or not. The mistake is that the bigger the power, the better. This is a misunderstanding. If you are not too familiar with ultrasound, you need to consult relevant engineering and technical personnel.
  • The structure of the ultrasonic mold needs to be strictly tested: the regular ultrasonic mold production feed has a set of strict inspection procedures, and the processing dimensions are processed by computer software simulation and verification. Quality is guaranteed. These processes are generally impossible to do. For example, if the mold is not properly designed, the reaction problem is not obvious when welding small workpieces. When there is high power, various disadvantages will occur. In severe cases, the power will be directly damaged. element.

  • The weldability of two kinds of workpieces during welding: some materials can be welded better, some are basically meltable, and some are not melted. The melting point between the same material is the same, and in principle it can be welded, but when the melting point of the workpiece to be welded is greater than 350 ° C, it is not suitable for ultrasonic welding. Since the ultrasonic is instantaneously melting the workpiece molecules, it is judged that within 3 seconds, the welding cannot be performed well, and other welding processes need to be selected. Generally, ABS material is easy to weld, and nylon or PP material is generally weldable.
  • Ultrasonic welding output power should be balanced: the output power is determined by the thickness and diameter of the piezoelectric ceramic piece, design process, material, etc. When the ultrasonic transducer is shaped, the high power is also shaped, and the output energy is measured. A complicated process, not the larger the ultrasonic transducer, the greater the output energy of the circuit. The more the ultrasonic power tube, the more complex the amplitude measuring instrument is needed to accurately measure its amplitude.
