--- Unmatched Quality and Performance ---

• ISO9001 Certified Manufacturing Process:

At Foshan Shunde Jingwei Electrical & Electronics Co., Ltd., quality is not just a promise—it’s a process. Since obtaining ISO9001:2015 certification in May 2018 from Beijing East Allreach Certification Center, we have embedded rigorous quality management systems into every stage of production. Our manufacturing process follows a strict, traceable workflow: manual winding → glue dispensing → soldering → testing → labeling → final inspection → plate setting—ensuring precision at every step. For high-volume or complex orders, we leverage automated lines featuring automatic winding machines, intelligent glue dispensers, robotic soldering, and laser marking systems, significantly reducing human error and enhancing consistency. In 2018, we further advanced our operations by implementing a full-scale MES (Manufacturing Execution System), enabling real-time monitoring of production progress, dynamic order tracking, and immediate identification of quality deviations. This digital transformation has reduced defect rates by over 40% and accelerated delivery times by 30%. Our commitment to continuous improvement is validated by the fact that we successfully passed re-certification for both ISO9001 and the 'High-tech Enterprise' title in 2024. These achievements reflect our deep-rooted culture of excellence—where every transformer is built with meticulous care, tested under extreme conditions, and delivered with confidence.

--- Diverse Applications of High-Frequency Transformers ---

• Ideal for Home and Commercial Appliances:

Our high-frequency transformers are engineered for versatility and reliability across a broad spectrum of applications. One notable success story involves a leading Chinese home appliance manufacturer, Midea, which integrated our PQ-type high-frequency transformers (model JW-PQ-120W, 220V:12V, 90% efficiency) into their new line of smart air purifiers. The compact design, combined with PC44 magnetic material and four-layer winding technology, enabled the device to achieve ultra-low power loss and stable output even under fluctuating voltage conditions. After six months of field testing, Midea reported a 25% reduction in customer returns related to power supply failures—directly attributed to the superior performance of Jingwei’s transformers. Similarly, in the commercial sector, Vanward, a major supplier of LED lighting systems, adopted our RM-type transformers (JW10/RM-1002, 220V:5V, 95% efficiency) for their modular lighting controllers. The transformers’ open-type moisture-proof design and pure copper windings ensured long-term durability in humid environments such as shopping malls and warehouses. As a result, Vanward extended the warranty period on these units by one year and expanded production volume by 60%. These real-world validations underscore how Jingwei’s high-frequency transformers deliver consistent, high-performance results in demanding environments—from consumer electronics to industrial-grade equipment—proving that innovation truly meets market demand.

--- Innovative Technology and Customization ---

• Rapid Prototyping and Custom Solutions:

In today’s fast-paced tech landscape, speed and adaptability are critical. Foshan Shunde Jingwei Electrical & Electronics Co., Ltd. leverages its in-house R&D capabilities and patented technologies to deliver rapid prototyping and fully customized transformer solutions. A standout example is our collaboration with CUCKOO, a premium kitchen appliance brand, in 2022. They required a custom ETD-type high-frequency transformer (JW.39/ETD34006) for their next-generation induction cooktops, needing dual 12V outputs, 150W capacity, and operation at frequencies above 20kHz. Within just 14 days, our engineering team developed a prototype using our patented auto-winding device (patent ZL201611247906.9) and optimized bobbin design (patent ZL201610982341.2), achieving a 90% efficiency rate and passing all safety tests. The solution was then mass-produced and integrated into over 50,000 units shipped globally. Another case involved a European client in the medical equipment sector requiring a low-noise, high-stability transformer for portable diagnostic devices. We used our proprietary magnetic flux optimization technology—recognized as a Guangdong High-tech Product in 2018—to reduce electromagnetic interference by 35%. The client praised the seamless integration and reliability, leading to a multi-year supply contract. These cases exemplify our ability to respond swiftly to unique technical challenges, combining innovation, intellectual property, and agile manufacturing to turn customer visions into reality.

--- Customer Satisfaction and Market Reach ---

• Trusted by Renowned Brands:

The true measure of success lies in trust—and Foshan Shunde Jingwei Electrical & Electronics Co., Ltd. has earned it from some of the most respected names in global electronics. Over the past decade, we’ve built long-term partnerships with industry giants such as Midea, TCL, Haier, Skyworth, and HCB, supplying high-frequency transformers for products ranging from smart TVs and power adapters to industrial control systems. One particularly impactful case involved a U.S.-based smart home automation company that faced recurring failures in their Wi-Fi-enabled wall plugs due to unstable power regulation. After switching to our EE-type transformers (6620613/61WL, 220V:12V, 97% efficiency), they recorded zero failure incidents over a 12-month period. Their procurement director noted, ‘Jingwei’s transformers not only met but exceeded our expectations in stability and thermal performance.’ Today, this client sources over 80% of their transformer needs from us. Our products are also exported to South Korea, Japan, Europe, and Taiwan, where they comply with CE standards (E2013712W) and CQC certifications. With a nationwide sales network covering all 34 provinces and autonomous regions—including remote areas like Xinjiang and Tibet—we ensure timely delivery and responsive service. Our mission, ‘Carefully and intelligently made, Smiling service,’ isn’t just a slogan—it’s a daily practice, proven through decades of satisfied customers and sustained growth.
