The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...

Here’s something that may be of interest to all the reprappers, vacuum formers, and other plastic fabbers out there: ultrasonic welding of plastics. If you’ve ever wanted to join two pieces of plastic ...

Several techniques are available for joining thermoplastic composites, including resistance welding and ultrasonic welding. While resistance welding uses Joule heating inside an electrically ...

Completion of the 8-meter-long thermoplastic composite (TPC) fuselage section comprised continuous ultrasonic welding of the MFFD’s right-hand (RH) longitudinal fuselage joint (left) and resistance ...

So, you’ve got your product design pretty much down and selected the materials with the properties the application requires, but some of the plastic parts need to be joined. You may discover that the ...

Plastic parts and assemblies are becoming more common as engineers work to reduce costs and weight in their designs. But plastics often aren’t strong enough to support fasteners such as screws or ...
