At Foshan Shunde Jingwei Electrical & Electronics Co., Ltd., innovation begins on the production floor. The company has invested heavily in intelligent manufacturing, deploying an advanced automated production line that integrates automatic winding machines, precision glue dispensers, robotic soldering stations, and AI-powered visual inspection systems. This shift from manual to semi-automated and now fully automated processes has significantly reduced human error while increasing consistency and throughput. For instance, the use of laser automatic marking and real-time visual comparison technology ensures every transformer’s serial number, model, and performance data are accurately recorded and verified during production. A key breakthrough came with the implementation of an automatic gluing machine for low-frequency coils (patented under ZL201921240740.7), which improved insulation stability by 30% and reduced moisture-related failures by over 45% in field testing. Additionally, the company’s proprietary automatic winding device (ZL201611247906.9) enables precise control over layer alignment and tension, resulting in fewer short circuits and higher efficiency—especially critical in high-frequency applications like switching power supplies. These technologies are not isolated; they are seamlessly connected via the company’s internal MES system, allowing real-time monitoring of production metrics such as defect rates, cycle times, and material usage. As a result, Jingwei can deliver custom orders within 7–10 days—a lead time unmatched in the domestic market. This level of operational sophistication allows the company to maintain consistent quality even when scaling up production for large clients like Midea and TCL. The combination of automation, data integration, and continuous process optimization ensures that each transformer is not only manufactured efficiently but also engineered for longevity and peak performance under real-world conditions.
