Discover ultrasonic welding technology in mask production

In the pandemic era, medical masks have become indispensable items. Have you ever wondered how the layers of fabric in masks connect together firmly and quickly? The answer is ultrasonic welding technology.

What is ultrasonic welding?

Ultrasonic welding is a pressure welding process that uses the mechanical energy of ultrasonic waves to cause local plastic deformation at the surfaces to be joined. This process generates heat due to friction, melting and bonding the materials together.

Ultrasonic welding process of masks:

1. Prepare materials:
   • Non-woven fabric layers: Filter layer, skin contact layer, outer layer.
   • Ear straps: Can be elastic or fabric.
2. Cut and layer:
   • The fabric layers are cut to standard sizes and stacked in the correct order.
3. Ultrasonic welding:
   • Place the fabric layers into the ultrasonic welder.
   • The machine emits ultrasonic waves, creating heat and pressure to weld the fabric layers together.
   • The soldering points are usually concentrated at the edges and where the ear straps are attached.
4. CHeck quality:
   • Check the strength of the welds.
   • Check the size and shape of the mask.
5. Packaging and distribution:
   • Pack the masks in boxes or bags.
   • Distribute to medical facilities, pharmacies or retail.

Advantages of ultrasonic welding technology:

• Fast: Welding process is fast, increasing productivity.
• Secure: The welds are very secure, ensuring the mask will not come loose.
• Hygiene: No glue used, ensuring safety for users.
• Energy saving: Consumes less energy than traditional welding methods.
