 Ultrasonic plastic welding machines involves the use of high frequency sound energy to soften or melt the thermoplastic at the joint. Parts to be joined are held together under pressure and are then subjected to ultrasonic vibrations usually at a frequency of 20, 30 or 40 kHz. The ability to weld a component successfully is governed by the design of the equipment, the mechanical properties o...

Ultrasonic plastic welding is a kind of thermoplastic jointing technology, which makes use of friction between molecules generated by ultrasonic horn. During ultrasonic welding, two plastic part halves are pressed together under pressure, ultrasonic system transform electric energy in 50/60Hz into mechanical energy in 15KHz, 20KHz, 28KHz, 30Khz, 35Khz, 40Khz by convertor, and strengthens it by boo...

 Introduction Three general types of reactors are used for biodiesel production: batch reactors, semi-continuous-flow reactors, and continuous-flow reactors. The batch process is inexpensive, requiring much less initial capital and infrastructure investment. It is flexible and allows the user to accommodate variations in feedstock type, composition, and quantity. The major drawbacks of the ba...

 Ultrasonic Welding Ultrasonic welding is the process by which two pieces of plastic are joined together through the use of high-frequency acoustic vibrations. For the process one half of the component is placed on a fixed anvil and the second half is placed on top. An extension, connected to the transducer on the welding machine, called a “horn” is then lowered down on top of the two compone...

 Sonochemistry Introduction The use of ultrasound in chemical reactions in solution provides specific activation based on a physical phenomenon: acoustic cavitation. Cavitation is a process in which mechanical activation destroys the attractive forces of molecules in the liquid phase. Applying ultrasound, compression of the liquid is followed by rarefaction (expansion), in which a sudden pres...
