How ZTC Successfully Supported a Japanese Industrial Electronics Manufacturer in Transferring Current Transformer Production to China
Table of Contents
Project Background
In today’s global manufacturing environment, many industrial electronics manufacturers are seeking to optimize supply chains, improve production flexibility, and maintain long-term competitiveness. Production line relocation is often a strategic decision, but it also presents significant challenges in quality control, process replication, and production continuity.
Xiamen ZTC Technology Co., Ltd. has been cooperating with a leading Japanese industrial electronics manufacturer since 2017, supplying current transformer products for industrial applications. Through stable product quality, responsive technical support, and consistent delivery performance, ZTC gradually earned the customer’s trust and became an important long-term manufacturing partner.
As market demand continued to grow, the customer faced increasing challenges in maintaining production capacity at its Japan-based manufacturing facility. Rising labor costs, higher operating expenses, and limited production capacity made it increasingly difficult to meet the delivery requirements of end customers while remaining cost-competitive.
To address these challenges, the customer initiated a production localization strategy and began evaluating qualified manufacturing partners in China. After a comprehensive assessment of technical capabilities, quality management systems, manufacturing experience, and long-term supply reliability, ZTC was selected to undertake the production transfer project.
By relocating production to China, the customer aimed not only to optimize manufacturing costs but also to significantly expand production capacity, improve supply chain flexibility, and support future business growth.
In early 2019, the customer initiated a strategic plan to transfer one of its current transformer production lines from Japan to China and selected ZTC as the manufacturing partner responsible for supporting the localization project.
The Challenge of Production Line Transfer
Unlike a simple outsourcing project, transferring a mature production line involves much more than duplicating equipment. The project required:
- Replicating existing manufacturing processes
- Maintaining product performance consistency
- Building a qualified production line within a limited timeframe
- Passing customer production audits
- Completing product validation and approval
- Ensuring a smooth transition without disrupting customer supply
For industrial current transformer products, even small variations in manufacturing processes may affect product performance, reliability, and long-term consistency. Therefore, process understanding and execution capability were critical to the success of the project.
On-Site Learning in Japan
To ensure a successful transfer, ZTC established a dedicated project team led by senior management.
In November 2019, ZTC engineers and project members traveled to the customer’s manufacturing facility in Japan to conduct on-site learning and technical exchange activities.
During the visit, the team studied:
- Production workflows
- 2.Manufacturing processes
- Quality control procedures
- Testing methodologies
- Operational management practices
This face-to-face technical communication helped ZTC gain a deeper understanding of the customer’s requirements and laid a solid foundation for the localization project.

Long-Term Results
Since May 2021, the production line has entered stable operation.
Through continuous quality management and reliable delivery performance, ZTC has maintained long-term supply support for the customer.
Key achievements include:
Successful transfer and localization of the production line from Japan to China.
- Establishment of a dedicated manufacturing line that passed customer audit and acceptance requirements.
- Successful completion of product validation and qualification processes.
- Stable pilot production launch and smooth transition into mass production.
- Significant improvement in production capacity to support the customer’s growing market demand.
- Enhanced supply chain flexibility and manufacturing scalability for future business expansion.
- Optimization of manufacturing costs compared with Japan-based production operations.
- Continuous stable supply and quality performance since 2021.
- Long-term customer recognition for product quality, technical support, and delivery reliability.
- Establishment of a trusted strategic manufacturing partnership supporting the customer’s long-term growth objectives.The success of this project demonstrates ZTC’s capability not only as a current transformer manufacturer, but also as a trusted partner capable of supporting industrial production transfer, process replication, and manufacturing localization projects.
Beyond the successful production transfer itself, the project enabled the customer to overcome capacity limitations and rising manufacturing costs associated with Japan-based production.
By leveraging ZTC’s manufacturing expertise, scalable production resources, and quality management capabilities, the customer achieved a more competitive supply chain while ensuring stable product quality and reliable delivery performance for its growing global market demand.
