VietSonic Ultrasonic Spot Welder for Mask Ear Loops – Automated, Precise, Labor-Saving

The Ultrasonic Spot Welding Machine for mask ear loops by VietSonic (28 kHz frequency, 300 W power, pneumatic operation) is the flagship device featured in the video by Dr. Nguyen Thanh Hai – Faculty of Mechanical Engineering, HCMC University of Technology. It demonstrates rapid welding capabilities, precision, and robust joint formation.

1. Ultrasonic Technology – Creating Durable, Glue-Free Bonds

  • 28 kHz Frequency, 300 W Power: Generates ultrasonic waves at the weld point, melting the non-woven substrate and the elastic loop to create a strong bond without discoloration or damage to the mask.
  • Chemical-Free Process: Creates a natural hermetic seal, environmentally friendly, and minimizes defects compared to sewing or gluing methods.

2. Design – Saving Labor, Stable Production

  • Pneumatic Automation: Combines a standard welding horn with PLC integration, ensuring stable productivity and reducing operating costs.
  • Aesthetic & Strong Welds: Pneumatic pressure combined with ultrasonic frequency ensures the ear loops are securely attached to the mask body, ideal for mass production.

3. Superior Advantages

     

  1. High Productivity & Precision: Suitable for both large-scale assembly lines and small workshops.

    2.  

  2. Easy Adjustment: Power parameters and welding time are flexible for various mask types.
  3. Quick Maintenance: Simple design, manufactured by VietSonic in Vietnam, ensuring rapid technical support.
  4. Cost Optimization: One-time investment for continuous welding, low defect rate, reduced labor, and fast return on investment (ROI).
