Ultrasonic Welding Machine – Precise, Durable PP Sheet Welding Solution | VietSonic

Introduction to Ultrasonic Welding Machines

The VietSonic ultrasonic welding machine is a modern solution, effectively replacing traditional thermal welding methods. Utilizing high-frequency ultrasonic waves (20–30 kHz) to create internal friction within PP (polypropylene) material, it ensures fast, beautiful, and strong welds without causing deformation or heating the entire surface of the advertising board.

As shown in the demo video, the machine can weld PP plastic sheets quickly, producing thin, aesthetic seams that meet high standards for mechanical durability and tightness.

Outstanding Advantages in PP Sheet Welding

  • Sharp & Strong Welds: No spreading melt, limited deformation.
  • Fast Processing Speed: Takes only a few seconds per weld point as seen in the video demo.
  • Energy Saving: Power range from 400–1000 W with high efficiency.
  • Safe, Clean, Eco-friendly: No smoke/dust, no chemical flux required, reduced fire/explosion risks.

Practical Applications

Main Structures

  • Advertising Signage: Welding large PP sheets, ensuring straightness and tightness.
  • Industrial Packaging: Finishing PP plastic boxes, specialized container shells.
  • Light Interior Products: Creating patterns, aesthetic joints.

The video demonstrates an advertising company successfully using the machine to weld PP advertising boards quickly with beautiful, strong welds.

Effective Usage Guide

  1. Surface Preparation: Clean the PP sheet, ensure it is flat.
  2. Select Suitable Sonotrode: Based on thickness and mold design.
  3. Parameter Setup: Adjust power, time, air pressure, or manual pressure according to material type.
  4. Execute Welding: Hold steady for uniform welds; after a few seconds, the machine reaches sufficient heat to bond.
  5. Quality Check: Test with a light pull, check flatness and tightness – the weld should meet standard requirements.
