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 !!!

Ultrasonic Welding Technology - The Key To The Production Of Masks


In the process of producing masks, ultrasonic welding technology has made a great contribution.


Principle of ultrasonic welding mask:


The frequencies usually used for non-woven welding processing are 20KHz and 15KHz. Ultrasonic energy penetrates the materials to make them fused together. Generally, tooth-like, mesh-like and strip-like patterns need to be made on the welding head to form patterns on the surface of the fused product, and to fuse the multi-layer fabrics. Disposable flat masks and N95 masks are manufactured in this way, and the ear straps of the masks are also spot-welded with ultrasonic waves.


Advantages of ultrasonic welding masks:


Superior speed and productivity
Ultrasonic welding technology cuts, sews and bonds nonwovens with extraordinary speed. In a continuous line, ultrasound can weld nonwoven layers in less than a second, resulting in a repeatable bond that is as strong as the parent material.


Strong, continuous seams and ties
The main advantage of ultrasonic welding technology compared to sewing is that high-strength, high-integrity seams and bonds can be created without the need for stitches and without the need to create mechanical holes in the fabric that can contain and hide microorganisms or contaminants thing.


Zero consumables or pollutants
Compared to adhesives, ultrasonic welding technology eliminates the additional cost of consumables, the additional work applied, the additional time required for installation and drying, and the risk of exposure to chemical contaminants. Ultrasonic seams are ready for use as soon as they are produced.


High energy efficiency
Ultrasonic welding technology consumes power only when it is used to cut or bond materials. Furthermore, since the process immediately generates the required frictional heat through ultrasonic vibrations, there is no additional energy consumption or waste associated with preheating and maintaining the hot knife or thermal bonding tool at the desired operating temperature.
