For enterprises contemplating the use of smart cards, the following four primary applications should be considered. While each one of these applications is a compelling use for sma

Sound is a vibration that is transmitted through a medium, such as air, water, and metals. Ultrasonic waves are an "inaudible sound," the frequency of which generally exceeds 20 k

Ultrasonic welding means joining without adhesives, screws or heat from an outside source. During this process, plastics are strategically melted by means of ultrasonic vibrations

Ultrasonic energy has found extensive use in cutting of textiles, woven sacks/plastic etc and their downstream processing. Many of these uses are based on the ability to use ultras

The biggest difference is that ultrasonic welding is a solid state process and arc welidng is a fusion process. A solid state welding process is one where the material is not melt

Ultrasonic welding of plastics is performed through vibrations which are presented perpendicularly to the joint. Heating is dependent on the loss modulus of the polymer, the freque

The main principle of a piezoelectric transducer is that a force, when applied on the quartz crystal, produces electric charges on the crystal surface.  The charge thus produced ca

The conversion of electrical pulses to mechanical vibrations and the conversion of returned mechanical vibrations back into electrical energy is the basis for ultrasonic testing. T
