Effective Ultrasonic Welding Solutions for Thin Films & Plastic Strips with VietSonic Multi-function Machines

1. Introduction to Thin Film Ultrasonic Welding Technology at VietSonic

Ultrasonic welding technology for thin films and plastic strips at VietSonic is the optimal solution for thin materials and engineering plastics. With a power output of up to 2,000 W and a frequency of 20 kHz, the device allows for the creation of sharp, strong weld lines without the use of glue or adhesive tapes – helping to reduce costs and production time more effectively.

2. Outstanding Advantages of VietSonic Multi-function Welding Machine

  • High Frequency, Large Capacity: 20 kHz combined with 2 kW power is suitable for a variety of materials such as PP, PE, ABS, PVC…
  • Strong, Airtight/Watertight Strip Welds when using specialized rollers.
  • Horn (Sonotrode) Design: Knurled/toothed design with expanded width helps increase productivity and precision.
  • Multi-functional Device capable of welding thin films, plastic strips, spot welding, cap reinforcement, non-woven fabrics, laminated films, etc., for multi-industry applications.

3. Operating Principle – Technical Depth

The machine works by converting ultrasonic waves into mechanical kinetic energy, causing the edges of the plastic material to vibrate at high frequency and create localized friction. The generated heat melts the plastic, bonding it tightly upon cooling – completely glue-free, smokeless, and with limited deformation.

4. Key Application Sectors

  • Thin Film Packaging, Laminated Films: Creating airtight seals, curtains, and packaging strips for multi-layer advertising films, as shown in the 20 kHz demo video working on aluminum-coated laminated films.
  • Product Edge Banding, plastic frames of various sizes.
  • Medical & Electronics: Welding masks, filter bags, and electronic component casings with high precision.
  • Automotive & Household Appliances: Welding interior trims, PE–PP plastic boxes, and large technical details.

5. Advantages of Choosing VietSonic – Local Presence, Global Standards
