PI - Piezoceramic Rings

In industrial power ultrasound welding, drilling or cleaning applications, for example, robust piezoceramic rings made of ferroelectric hard PZT are used in a stacked configuration. On the contrary, in a mesh nebulizer, thin ferroelectric soft PZT rings are glued to a metal membrane to create tiny medication droplets for inhalation by patients with respiratory disorders.

Rings provide a decisive benefit over disks: They can be fixed by tensioning screws to achieve mechanical preload in the ceramic material.
It is also possible to further refine individual rings or to combine them to form transducer elements. Especially in assembling >> power ultrasonic transducers, piezo rings are energy-efficient, compact, and versatile components. Depending on the design, torsional movements can also be implemented in addition to longitudinal displacements.

With more than thirty years of expertise in the development and production of piezoceramics, PI Ceramic offers end-to-end service extending from the selection of the suitable material through to the development of application-based solutions. The data of the piezo rings can be selected within specification limits. For a feasibility check, please send us your specifications or the dimensions for the piezoceramic ring.
