WELDING CHARACTERISTICS: Unlike welding of rigid plastic parts, the ultrasonic welding of textiles and films relies on a pattern or design on the tooling to focus the ultrasonic energy and produce a melt. This geometry can be located on the face of the horn, anvil, rotary drum, or stitching wheel. These patterns are listed in Branson data sheet PW-45. In general, favourable material characteristic...

Mechanical methods includes Expression/Expeller press Ultrasonic-assisted extraction The simplest method is mechanical crushing. Since different strains of algae vary widely in their physical attributes, various press configurations (screw, expeller, piston, etc) work better for specific algae types. Often, mechanical crushing is used in conjunction with chemicals.Expression/Expeller press:Algae i...

 Our new equipment -Ultraosonic degassing device with ceramic sonotrode  Any gas (unless intentionally blasted through the melt) is usually completely dissolved in the liquid metal and no free bubbles exist in the liquid volume. Therefore, the theory of ultrasonic degassing well developed for water (e.g. by Kapustina) is only applicable to the liquid metals after the cavitation star...

  Sonication has numerous effects, both chemical and physical. The chemical effects of ultrasound are concerned with understanding the effect of sonic waves on chemical systems, this is called sonochemistry.The chemical effects of ultrasound do not come from a direct interaction with molecular species. Studies have shown that no direct coupling of the acoustic field with chemical species on a...

 Dicing with ultrasonic technology has been developed as a new application to support the processing of electronic components (ceramic parts) and optical devices (optical disc parts, optical transmission parts). Using ultrasonic technology will enable the processing of materials such as glass and ceramics, which until now have been difficult to cut with a blade. Issues when processing difficu...

 Use in medicine Main article: Medical ultrasonography Medical ultrasonic transducers (probes) come in a variety of different shapes and sizes for use in making pictures of different parts of the body. The transducer may be passed over the surface of the body or inserted into a body opening such as the rectum or vagina. Clinicians who perform ultrasound-guided procedures often use a probe pos...
