Plastic welding through ultrasonic applications

Plastic welding through ultrasonic applications

There would be no electrical cable insulation or plastic containers without plastic welding, making it an ideal option for limitless creation.

Plastic welding creates a molecular bond between two compatible thermoplastics. Ultrasonic welding is one of the methods used to weld plastic.

Ultrasonic welding

Ultrasonic plastic welding uses heat generated through high-frequency acoustic vibration. As a result, high-frequency electrical energy is converted into high-frequency mechanical motion. That mechanical motion, combined with applied force, creates frictional heat at the joining points, resulting in a molecular bond in a matter of seconds.

Benefits of plastic welding

  • No messy or hazardous consumables are used in plastic welding.
  • Plastic welding generally doesn’t require specific surface preparation steps.
  • A plastic weld is permanent, unlike mechanical fasteners and adhesives.
  • Plastic welds are lightweight and create leak-tight, airtight seals.

Advantages of ultrasonic welding

  • Very fast process of typically less than a second.
  • Ultrasonic welding equipment offers advanced control and monitoring features.
  • Ultrasonic welding is an economical process.

Plastic welding tips

  • Always weld like-plastic with like-plastic.
  • Ensure your workspace is well-ventilated.
  • Use heat-resistant gloves and wear long-sleeved protective clothing.
  • Clean the welding plastic with soap and water and remove debris and dry plastic.
  • Keep the pieces of plastic together with a clamp and tape.
  • Form the joint before you turn on the torch.

Types of plastic welding seams

  • A fillet weld is one of the most frequently used seam geometries produced by welding two pieces that meet in a T-joint.
  • An interior corner seam is often used in difficult-to-reach locations.
  • V-seams are created when the workpieces are bevelled at the correct angle to each other.
  • X-seams or double V-seams combine two V-seams on each side of the parts to be joined.
  • Lap seams are generally used for plastic sheets arranged on top of each other.
