Ultrasonic Welding for Staking, Riveting, and Pin Fixing – Optimal Solutions from VietSonic

Introduction

Ultrasonic welding machines are high-tech equipment widely used in the field of technical plastic processing. One of the most prominent applications is staking (forming plastic stud heads), riveting, and fixing positioning pins. VietSonic – the leading provider of ultrasonic technology in Vietnam – delivers effective, rapid, and high-precision solutions for modern manufacturing needs.

Applications of Ultrasonic Staking, Riveting, and Pin Fixing

What is Staking?

Ultrasonic Staking (or mushroom heading) is the process of melting a plastic stud to fix another component, such as metal, rigid plastic, or a PCB, into a desired position. Ultrasonic technology uses high-frequency vibrations to generate localized heat, melting the stud tip and forming it according to the tooling die.

Advantages of Ultrasonic Staking Technology:

  • Eliminates the need for screws or adhesives.
  • Fast welding speed, saving production time.
  • Strong, highly aesthetic joints.
  • No deformation of surrounding components.
  • Suitable for electronics, automotive, home appliances, medical devices, etc.
