 Welding Assembly by "Energy focuser". Essentially limited to « amorphous » thermoplastics. Welding is rapidly performed (less than 1 second), without additional material. Spot welding Particularly recommended for thermoformed parts lacking assembly profile, or for pieces with geometry and imposed conditions making the usual welding inoperative. Continus welding Applied to high-speed processe...

A little research reveals that ultrasonic plastic welding machines can be purchased in a variety of frequencies, including 15, 20, 27, 30, 35, 40, 50, 60, or 70 KHz. As if this doesn’t create enough confusion, even more frequencies most likely are available. If two potential suppliers recommend different frequencies, which one is providing the best information? If an ultrasonic welder of one frequ...

Ultrasonic metal welding is a solid-state welding process that uses localized high-frequency vibratory energy in conjunction with moderate clamping force. It does not require consumables — such as welding rods, fluxes, fillers, or solders — or special cleaning methods. This energy-efficient, environmentally-friendly system produces no arcs or sparks. It is excellent for joining non-ferrous dissimi...

  Experimenting with the PolyScience Sonicprep™ Ultrasonic Homogenizer    The nice folks at PolyScience generously loaned me a Sonicprep ultrasonic homogenizer for a few weeks of experimentation.  If the last sentence sounded like gibberish, it’s probably a good idea to read Jethro’s post on our experiments for a little background knowledge.  The Sonicprep is a device that...

1.Principle The working principle of ultrasonic plastic welding machine: using ultrasonic vibration frequency, contact friction generates heat to melt and combine plastic. According to the current, it is 20,000 times per second (20 kHz) and 15,000 vibrations per second ( There are two kinds of special vibration frequencies, 15 kHz. Because of the limited space, only the two common fusions of ...
