Ultrasonic Welding and Standard Piezo Cylinders
Ultrasonic vibrations produced by piezoelectric ceramic elements can be used to generate heat to weld or melt thermoplastics.
In order for an ultrasonic transducer to be used in a welding application the longitudinal vibrations on the end of the transducer need to be amplified and concentrated onto a small surface area. This is accomplished through the use of an amplitude transformer, or horn, manufactured from a titanium or aluminum alloy.
In ultrasonic welding, the horn is brought into contact with one piece of thermoplastic that is to be joined to another piece. Pressure is applied to the two pieces of thermoplastic and the ultrasonic vibrations pass through the first piece to the interface with the second piece. Frictional heat at this interface will melt the material and once the vibrations stop, the temperature drops, and the plastic solidifies the two pieces of plastic will have bonded together.
Using ultrasonic transducers for welding is beneficial because it is:
– Fast and efficient
– Produces a strong bond
– Eliminates the use of solvents and adhesives
– and Heat generated is confined and thus rapidly dissipated
Standard Piezoelectric Cylinders
APC offers piezo cylinders in a wide range of standard sizes allowing customers to move quickly on R&D projects.
APC’s standard piezo cylinders come in a wide variety of standard dimensions and are available in both hard and soft PZT materials. These cylinders can often be delivered to customers in less than a week.
Standard piezo cylinders can be used in many applications or devices that use piezo sensors such as:
– Ultrasonic or Doppler flow meters
– Gas flow sensors
– Flow or level sensors
– NDT/NDE applications
– sensor inspection for construction material and welds in automotive, structural, and other applications
