1. What is ultrasonic plastic welding? How does ultrasonic plastic welding work?

  • Ultrasonic plastic welding is the process of joining two or more thermoplastic articles together by the use of heat generated from the high-frequency mechanical motion of the welder.
  • The mechanical motion combined with applied external force creates friction which generates a large amount of heat as the plastic surfaces experience a constant rubbing/mating force.
  • The ultrasonic waves produced actually is because they vibrate 10’s thousands of times per second. This vibration produced is transferred when there is contact with the plastic parts.
  • Once the welding boundary has a lot of high-frequency impedance forming on it, its temperature gradually increases.
  • Being a poor conductor of heat, the plastic melts down and joins the two parts to blend together when some amount of pressure is applied. When the ultrasonic radiation is no more applied, the plastic solidifies again.

2. Where is ultrasonic welding used?

  • Ultrasonic welding is extensively used in the electrical and computing industry to weld the wired connections together and also create small and delicate circuits. Moreover, wire harnesses are also used to distribute electrical signals and power using this method.
  • Ultrasonic welding is used in aerospace and automotive industries for welding together large plastic assemblies and electrical components like instrument panels, doors, lamps, air ducts, steering wheels, and other engine components.
  • In the medical industry, ultrasonic welding is used as it does not cause any contamination or degradation in the chemicals manufactured and the machines manufactured are specialized to be used in cleanrooms only.
  • In the year 2000, ultrasonic welding was used to manufacture LZE Racer swimsuits.

3. How do you weld plastic with a soldering iron?

  • Clean the plastic material with soap and degreaser. Make sure you sharpen and rub the edges of the plastic with sandpaper so that they do not get jagged later on.
  • Put the soldering iron inside it and let it heat properly.
  • Make sure you push the two pieces of plastic articles together and then run the soldering iron tip back and forth to melt the plastic together. When the plastic joints are molten and hot, make sure you place the plastics well-aligned.
  • Add more plastic to the seam in order to strengthen the layers. Once you liquefy plastic using the soldering iron, spread the plastic along the seam using the soldering tip.
  • Go over the seam and surrounding areas using the soldering iron using fast and smooth strokes to create an even and smoothly welded surface.
