Piezo ceramic components are widely used in ultrasonic transducers, cleaning systems, welding equipment, medical ultrasound, sensors, actuators, flow meters, and underwater acoustic devices. Because each application may require different dimensions, resonance frequencies, electrode designs, and installation methods, custom piezo ceramic components are often necessary.
China Ultrasound provides custom piezo ceramic components in a wide range of shapes, sizes, materials, electrodes, and mechanical tolerances. Whether you need a standard PZT ceramic disc, a ring, a tube, a plate, or a complex customized piezo element, we can support production according to your drawings, samples, or application requirements.
Available Custom Shapes
We can manufacture a variety of piezo ceramic shapes for different ultrasonic and sensing applications. Common custom shapes include:
- Piezo ceramic discs
- Square and rectangular piezo ceramic plates
- Piezo ceramic rings
- Piezo ceramic tubes
- Hemispherical piezo ceramics
- Focal bowl piezo ceramics
- Tapered stave ceramics
- Barrel stave ceramics
- Other customized shapes based on drawings
In addition to the shapes listed above, custom shapes may also be available depending on the required size, ceramic thickness, material properties, electrode layout, and machining process.
Supported Size Ranges
The following size ranges are for general reference. The final manufacturability depends on the ceramic material, shape complexity, electrode design, tolerance requirements, and order quantity.
Piezo Ceramic Disc
| Parameter | Supported Range |
|---|---|
| Diameter | 3 mm – 255 mm |
| Thickness | 0.2 mm – 25 mm |
Piezo ceramic discs are commonly used in ultrasonic cleaning transducers, atomizers, sensors, buzzers, and various power ultrasonic devices. Disc dimensions are usually selected according to the target resonance frequency, vibration mode, and installation structure.
Square and Rectangular Piezo Ceramic Plate
| Parameter | Supported Range |
|---|---|
| Length | 1 mm – 165 mm |
| Width | 1 mm – 165 mm |
| Thickness | 0.2 mm – 35 mm |
Square and rectangular piezo ceramic plates are suitable for sensors, actuators, stacked structures, vibration modules, and custom ultrasonic transducer assemblies. They can be customized for different length, width, thickness, electrode coverage, and polarization requirements.
Piezo Ceramic Ring
| Parameter | Supported Range |
|---|---|
| Outside Diameter | 3 mm – 150 mm |
| Inner Diameter | 0.5 mm – 140 mm |
| Thickness | 0.2 mm – 25 mm |
Piezo ceramic rings are frequently used in bolt-clamped ultrasonic transducers, ultrasonic welding transducers, ultrasonic machining systems, and assemblies that require a central mounting hole. The outside diameter, inner diameter, and thickness can be adjusted to match the mechanical design of the transducer.
Piezo Ceramic Tube
| Parameter | Supported Range |
|---|---|
| Outside Diameter | 1 mm – 150 mm |
| Inner Diameter | 0.5 mm – 140 mm |
| Length | 1 mm – 150 mm |
Piezo ceramic tubes are used in hydroacoustic transducers, flow meters, sensing devices, actuators, and radial vibration applications. Tube components can be designed with customized outside diameter, inner diameter, length, electrode pattern, and polarization direction.
Hemispherical Piezo Ceramic
| Parameter | Supported Range |
|---|---|
| Outside Diameter | 6 mm – 203.2 mm |
| Wall Thickness | 1 mm – 10 mm |
Hemispherical piezo ceramics are suitable for special acoustic field designs, underwater acoustic devices, directional sound applications, and focused ultrasonic structures. They are often selected when the acoustic output direction and curved ceramic geometry are important to the final device design.
Focal Bowl Piezo Ceramic
| Parameter | Supported Range |
|---|---|
| Diameter | 6 mm – 203.2 mm |
| Thickness | 1 mm – 10 mm |
Focal bowl piezo ceramics are designed for applications that require acoustic focusing, such as medical ultrasound, non-destructive testing, high-intensity ultrasound systems, and underwater acoustic equipment. For focused ceramic structures, the diameter, curvature, thickness, electrode area, and frequency target should be evaluated together.
Customizable Parameters
In addition to shape and size, China Ultrasound can support customization of multiple technical parameters. The final design should consider the ceramic material, manufacturing process, electrode structure, and target application.

Standard Mechanical Tolerances
For most custom piezo ceramic components, the following standard mechanical tolerances can be used as a reference.
| Item | Standard Tolerance |
|---|---|

| Inner Diameter | ±0.15 mm |
| Length and Width | ±0.15 mm |
| Thickness | ±0.05 mm |
| Squareness, edge to face | Within 0.15° |
| Concentricity | 0.2 mm TIR |

| Surface Flatness, large flat parts | 15 μm |
| Parallelism, small gapped parts | 12 μm |
| Parallelism, large gapped parts | 60 μm |
| Surface Finish | Ra 3 μm |
For general “as-fired” dimensions, the typical tolerance is ±0.3 mm or ±1%, whichever is greater. If your application requires tighter tolerances, please provide detailed drawings so that our engineering team can evaluate the machining feasibility.
