VietSonic Ultrasonic Velcro Strap Welder – Premium Glue-Free Textile Solution

1. General Introduction

The VietSonic Ultrasonic Velcro Welding Machine is currently the top choice for manufacturers of hook-and-loop fasteners (Velcro). Utilizing a 20 kHz frequency and power up to 2 kW depending on the strap width, the device creates strong, highly aesthetic welds without causing plastic deformation or melting issues.

2. Operating Mechanism

  • Operates based on high-intensity ultrasonic waves (20 kHz) to generate friction at the contact area.
  • Frictional energy creates heat, melting the plastic interface on the Velcro surface, tightly welding the strap edges together.
  • Advantages: Fast, clean, chemical-free, and does not damage the surface quality.
