How to seal the copper tube with ultrasonic waves after injecting refrigerant

Ultrasonic Sealing is an efficient sealing method suitable for various materials, including metallic copper. This process utilizes ultrasonic vibration to generate frictional heat, thereby heating and connecting the materials together. The following is how to use ultrasonic sealing method to seal copper tube:

Preparation work:

Ensure that the end of the copper tube has been filled with refrigerant.

Prepare ultrasonic sealing equipment, including ultrasonic welding heads and control panels.

Cleaning treatment:

Ensure that the end surface of the copper tube is clean and free from impurities or dirt.

Remove any debris that may affect the sealing quality.

Assembly fixture:

Place the copper tube in a dedicated fixture to ensure that it remains in the position where it needs to be sealed.

Ultrasonic welding:

Start the ultrasonic welding equipment and set appropriate parameters, such as amplitude and time.

Ultrasonic welding joints will vibrate and generate frictional heat, heating the ends of copper tube.

When the end of the copper tube reaches sufficient temperature, the ultrasonic welding joint will apply pressure to seal the pipe end.

Cooling and curing: 

Wait for the end of the copper tube to cool and cure to ensure complete sealing.

nspection:

Check the sealing points to ensure there are no cracks or leaks.

Please note that ultrasonic sealing is a high-precision sealing method that can be achieved without adding other additional materials. This is a fast, controllable, and precise process suitable for many applications, including refrigeration and other precision engineering fields. Ensure that operators have the necessary training and experience before performing ultrasonic sealing to ensure high-quality sealing. In addition, the parameters and operating methods of the sealing equipment may vary from manufacturer to manufacturer, so the operation should be carried out according to the equipment's user manual.
