In the field of industrial manufacturing, wire harnesses are like the "nervous systems" of equipment, and their quality directly determines the performance and service life of the complete machines. Relying on two decades of dedicated R&D and manufacturing of industrial wire harnesses, Shengyangming Electronics has transformed from a basic industrial wire harness manufacturer into a long-term core supplier for multiple listed companies, writing a chapter about the rise of a hidden champion in China's manufacturing industry.

I. Two Decades of Technical Accumulation: From Process Breakthroughs to Industry Leadership
Since its establishment in 2006, Shengyangming has adhered to the development strategy of "technology-driven enterprise development". Faced with the high-precision requirements of the industrial wire harness sector, the company has continuously overcome core technical challenges in materials science and connection processes:
In the field of materials, Shengyangming’s R&D team has successfully developed high-precision copper alloy wire processing technology. This innovation has improved the product’s conductivity by 30% and expanded the temperature resistance range to a wide span of -40℃ to 150℃, meeting the stringent operational requirements of harsh industrial environments such as new energy vehicles and photovoltaic inverters. The independently developed UV-resistant photovoltaic wire harnesses have achieved a service life of over 25 years, helping clients’ products pass TUV certification smoothly.
In terms of manufacturing processes, the company has introduced intelligent equipment such as fully automatic terminal crimping machines and SMT placement lines, achieving an industry-leading wire harness processing precision of ±0.05mm. By establishing a modular design system, Shengyangming can provide customized prototype solutions within 72 hours according to customer requirements. At present, the company develops more than 100 new products annually and has obtained 14 patent technology certifications in total.

2. Intelligent Manufacturing System: Building the Foundation for Large-Scale and High-Quality Production
Shengyangming has built a 6,000-square-meter modern intelligent factory, equipped with more than 20 automated production lines, with an annual production capacity exceeding 50 million sets of wire harnesses. The company strictly implements the ISO9001/IATF16949 quality management systems, carries out the 7S on-site management, and its product processes comply with the IPC620 international standard.
Throughout the production process, Shengyangming has achieved the following results:
- Automated Processing: Smart production lines are composed of fully automatic wire cutting machines, terminal crimping machines and continuity testing equipment.
- Digital Management & Control: The MES system enables full-process production visualization, with real-time monitoring of key process parameters.
- Flexible Production: Supports small-batch customization with a minimum order of 50 units; provides samples of ordinary materials within 3 days and delivers urgent orders within 72 hours.
Through the upgrading of intelligent manufacturing, the defect rate of the company's production lines is controlled below 0.3%, meeting military-grade quality standards. Its products have been certified by leading enterprises such as Huawei and BYD.
3. Rigorous Quality Control System: Building the Cornerstone of Supply Chain Trust
The key to becoming a core supplier for listed companies lies in establishing irreplaceable quality trust. Shengyangming has built a full-process quality assurance system:
The company strictly implements the ISO9001 and IATF16949 international quality standards, enabling full traceability from raw material warehousing to finished product delivery. All products must pass more than 30 rigorous tests, including:
- High-voltage insulation test (up to 10kV)
- Salt spray corrosion test (96 hours)
- Vibration fatigue test (1 million cycles)
- Temperature shock test (-40℃ to 150℃)
This relentless pursuit of quality has kept the failure rate of Shengyangming's products below 0.1%, accounting for less than 0.1% of the fault factors in customers' equipment. Consequently, the company has become a certified supplier for leading enterprises such as Huawei and BYD.

5. In-depth Customer Collaboration: Leap from Supplier to Strategic Partner
Shengyangming goes beyond the role of a traditional supplier and achieves in-depth collaboration with listed companies through three core strategies:
Proactive R&D Involvement Model
Join in the optimization of wire harness solutions at the initial stage of customers’ product design. The company once developed a micro wire harness system for a listed medical enterprise, helping reduce the equipment volume by 40% and enabling the device to successfully obtain FDA certification.
Global Resource Integration
Establish direct procurement channels for international brand terminals (JST, TE, Molex, etc.). While ensuring material consistency, this measure has reduced procurement costs by 15%. At present, products are exported to more than 20 countries including Japan, Europe and the United States, with overseas revenue accounting for 35% of the total.
Rapid Response Mechanism
Create a service standard of "24-hour technical response + 72-hour sample delivery". In 2024, the company urgently delivered 2,000 sets of customized wire harnesses for a leading industrial automation enterprise, completing the whole process from order receipt to shipment in only 72 hours.
V. Sustained Innovation: Technological Layout for Industry 4.0
Facing the development trend of Industry 4.0, Shengyangming continues to increase investment in technological innovation:
- High-speed Data Transmission: Invest in the R&D of HPC high-speed wire harnesses to meet the 1.6T transmission demand of AI servers.
- Green Manufacturing: Develop degradable and environmentally friendly wires to help customers achieve ESG goals.
- Intelligent Prediction: Build an industrial wire harness life prediction system to realize the full life cycle management of products.
The company is now a national high-tech enterprise, with R&D investment accounting for 8% of total revenue. It has a professional R&D team of more than 20 people and launches over 100 new products every year.
6. Customer Testimonials: The Long-term Choice of Listed Companies
Shengyangming has provided products and services for more than 300 industrial enterprises worldwide, including many listed companies:
·Industrial Automation Sector: Supply servo wire harnesses for a listed automation enterprise, reducing equipment failure rate by 40%.
- New Energy Sector: Develop UV-resistant wire harnesses for a leading photovoltaic enterprise, extending the service life to 50 years.
- Medical Device Sector: Customize micro wire harnesses for listed medical device companies, helping them obtain FDA certification.

A Manufacturing Enlightenment from Two Decades of Persistence
The rise of Shengyangming has verified the core logic of high-quality development in the manufacturing industry: technical accumulation is the foundation, quality trust is the bridge, and value co-creation is the future. While many enterprises chased short-term profits, Shengyangming spent two decades polishing wire harnesses—a "small component"—and ultimately secured long-term orders from listed companies.
In the era of Industry 4.0, only enterprises that deeply integrate technological prowess with customer demands can become irreplaceable "hidden champions" in the industrial chain. Shengyangming’s journey reveals that the transformation and upgrading of the manufacturing industry does not lie in scale expansion, but in pursuing excellence in basic components. This is exactly the inevitable path for China’s manufacturing industry to evolve from "large" to "strong".
