Acceptance & Terms
Start with the closest application family
Use the published product hubs to identify a practical starting point. Specify whether you need a bare ceramic element, a housed transducer, or an assembled unit. The quotation confirms the supplied parts and the integration work that remains with your team.
Define the operating boundary
Frequency, drive or power, working medium, beam or acoustic target, mounting interface, duty cycle, temperature, and sealing requirements are reviewed together.
Agree the evidence before quotation
Dimensions and the applicable electrical or acoustic checks, sampling, records, quantity, and schedule are confirmed for the actual project rather than assumed from a generic supplier promise.

Frequently Asked Questions
- What types of ultrasonic transducers do you manufacture?
- YJ Piezo publishes transducer families for cleaning, welding, flow measurement, sensing, beauty-device, and underwater applications. Current model pages span 14.9 kHz to 5 MHz; targets outside a published model are reviewed as application-specific requirements.
- Do you provide custom transducer development?
- Yes, we offer complete custom development services from concept to production. Our engineering team designs transducers optimized for your specific application requirements and performance criteria.
- What is your production capacity?
- Production planning is reviewed by product family, tooling, process steps, validation requirements, and forecast quantity. Share the pilot and annual demand so engineering and production can confirm an appropriate batch plan.
- Can you provide prototypes and samples?
- Yes. Standard-model samples and custom prototypes are reviewed separately. Availability and timing are confirmed after the target frequency, mechanical interface, driver condition, operating medium, quantity, and required test records are known.
- What quality assurance processes do you follow?
- We follow comprehensive quality assurance including incoming material inspection, in-process testing, final performance validation, and reliability testing. Each transducer is individually tested before shipment.
- Do you offer global shipping and support?
- Yes, we ship worldwide with established distribution networks. We provide technical support, application guidance, and after-sales service globally through our technical team.
- How are warranty and acceptance terms handled?
- Warranty, acceptance criteria, and the response process are confirmed in the quotation or project agreement for the selected model or custom build. The terms depend on the operating conditions, integration boundary, validation plan, and agreed specifications.
- Can you handle high-volume production?
- Yes, we have scalable production capabilities and can handle orders from hundreds to tens of thousands of units. We maintain consistent quality and delivery schedules for high-volume requirements.
