Choose by geometry
Start from the element shape your design already implies
Most piezo component RFQs resolve to one of three base geometries. Each shape page carries dimensional ranges, mode behavior, and the RFQ inputs we need for that geometry.
- Piezo discsThickness-mode workhorse for cleaning, flow, and sensing; radial modes set the diameter floor.
- Piezo ringsBolt-clamped power stacks and preloaded assemblies; ID/OD ratio drives the frequency plan.
- Piezo tubesRadial transmit-receive and scanning elements; wall thickness sets sensitivity limits.

Custom Manufacturing Capabilities
Custom piezoelectric components, elements, and actuator ceramics for OEM programs
Yujie supports custom piezoelectric transducer elements and piezoelectric components when a standard catalog shape does not fit the device. For piezo actuator manufacturer searches, the right fit is custom ceramic plates, blocks, stacks, benders, or motion-control elements supplied as OEM components, not a generic finished actuator stage.
Custom Piezoelectric Component Design
Adjust diameter, thickness, length, inner diameter, curvature, electrode pattern, metallization, lead wires, and mounting features for discs, rings, plates, tubes, stacks, and special ceramic geometries.
Material and Performance Targeting
Select PZT-4, PZT-5A, PZT-5H, PZT-8 style grades or custom formulations around sensitivity, Qm, dielectric loss, Curie temperature, capacitance, impedance, and resonance targets.
Prototype to Production Support
Move from application review to sample validation, outgoing impedance or capacitance records, dimensional inspection, pilot batches, and volume production with traceability requirements agreed upfront.
Manufacturing Scope
Batch planning follows material, dimensions, electrode, and inspection requirements
Assembly and validation scope is confirmed against the final interface and operating conditions
Pilot and production quantities are quoted after drawing and process review

Frequently Asked Questions
- Do you support custom piezoelectric components and transducer elements?
- Yes. Yujie supports custom piezoelectric components including discs, rings, plates, tubes, blocks, stacks, benders, electrode patterns, metallization, lead wires, and assembly-ready ceramic elements. The engineering review starts from your target frequency, geometry, electrical limits, operating medium, and production volume.
- Are you suitable for piezo actuator manufacturing projects?
- Yujie can support piezo actuator projects at the ceramic component level, including plates, blocks, stacks, benders, and custom motion-control elements. We avoid presenting a generic finished actuator stage unless the application requirements, displacement target, load, driver condition, and integration boundary have been reviewed.
- What piezoelectric component shapes do you manufacture?
- We manufacture discs, rings, plates, tubes, hollow spheres, and custom geometries. Standard shapes available from stock, custom shapes manufactured to your specifications with precision machining.
- Do you provide OEM customization services?
- Yes, we offer comprehensive OEM services including custom shapes, dimensions, electrode configurations, and packaging. Our engineering team works directly with your specifications and requirements.
- How are sample quantities, production quantities, and schedules confirmed?
- They are confirmed after the geometry, material, electrode, electrical targets, inspection needs, and quantity are reviewed. Some validated catalog builds can start with smaller engineering quantities, while custom tooling or special processes require a project-specific production plan.
- Can you provide samples for testing?
- Yes. For a sample review, send the closest catalog model or drawing, target material, electrical requirements, operating environment, and quantity. Availability, cost, test records, and dispatch timing are then confirmed for that specific build.
- What quality certifications do you have?
- Dimensional inspection, electrical characterization, and agreed performance checks can be included in the quality plan. Share the certificate, inspection report, or traceability requirements with the RFQ so the applicable document set can be confirmed before quotation.
- Do you ship internationally?
- We support international shipments and coordinate export documentation and protective packaging according to the product, destination, and agreed delivery terms.
- What technical specifications can you achieve?
- Published catalog model specifications currently span 14.9 kHz to 5 MHz. Component-level capacitance, resonance, electrode, geometry, and tolerance targets are reviewed against the selected material and finished-device operating conditions.
- Do you offer application engineering support?
- Yes, we provide application engineering support including component selection, circuit design recommendations, and performance optimization for your specific piezoelectric applications.
