About YJ Piezo
YJ Piezo began as part of Yujie Technology's international business and website operations. It is gradually developing a more distinct customer-facing identity, while YJ Piezo and Yujie Technology continue to work closely across customer service, engineering, manufacturing, and project delivery.
Features & Applications
Evolving YJ Piezo Operations · Shared Industry Heritage
From Yujie to YJ Piezo
The industry experience presented here includes work begun in 1996 within the earlier Yujie business. YJ Piezo carries that experience forward for international OEM projects while remaining closely connected to the people and operating resources behind Yujie Technology.
Direct Project Coordination, Practical Manufacturing Support
Our model connects direct customer coordination with the established engineering and manufacturing resources shared across the relationship. Requirements, inspection scope, documentation, packing, and delivery planning are reviewed for the specific component and order rather than assumed from a category-level promise.
A Look Back at Our Early Years

Manufacturing Operations in Wuxi, China
YJ Piezo coordinates international projects with manufacturing operations in Wuxi, China. The supporting production capabilities include ceramic processing, machining, and component production for piezoelectric and ultrasonic applications.
Product requirements, inspection scope, and documentation are confirmed for each OEM project before production.
From Engineering Review to Production
Engineering Quantities
Sample scope and validation steps are planned around the part and application.
Batch Production
Production quantities and delivery schedules are confirmed after technical review.
Inspection Scope
Critical dimensions and electrical checks are defined against the agreed specification.
This project-based approach supports standard parts, custom ceramic geometries, and ultrasonic assemblies without presenting a general production figure as a guarantee for every product family.
