Piezoelectric rings for Inkjet Printer
Piezoelectric ceramic ring
Electrode direction: thickness
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
Piezoelectric Ceramic Material: PZT-41 (equal to PZT-4D)

The following piezo materials is for the vibration transducer
P-41 |
is equal to PZT-4D hard PZT. It is designed for higher dielectric constant, high Q m , high coercive field, high coupling and high stiffness required high power high driving transducers etc. |
P-42 |
Is a modified hard PZT, higher dielectric constant of P-41. |
P-43 |
is a modified hard PZT. It is developed for higher dielectric constant, high coupling and high stiffness required high power high driving etc. transducers |
P-82 |
Is equal to PZT-8, hard PZT for higher mechanical quality factor, lower dielectric loss required and much higher power handling capability etc. transducers. |
PCrN-4 |
is a modified PZT dedicated for extremely high power high driving etc. transducers with higher power handling capability than DL-43, dual function of receiver and transmiting transducer. |
PbaS-4 |
is a modified hard PZT developed for extremely high dielectric constant, high Q m , high stiffness and low dissipation factor required high frequency transducers etc. |
