Evolving Demands in Smart Manufacturing
As a global leader in electric vehicle innovation, BYD has continuously advanced its smart factory infrastructure. Its automated assembly lines involve a network of robotic arms, PLCs, sensors, and distributed control systems — all of which rely on robust, flexible, and easy-to-integrate terminal junction boxes.
To meet the stringent operational standards of BYD’s EV assembly process, Saipwell was selected as a solution provider for custom-designed terminal junction boxes, enabling seamless signal and power distribution across key automation nodes. This collaboration demonstrates Saipwell’s capabilities in fast prototyping, modular engineering, and industrial-grade enclosure production.
Product project requirements
Terminal Junction Boxes usually meet the following requirements:
- IP65+ environmental protection, resistant to dust, moisture, and vibration；
- Flexible structural customization to adapt to specific wiring layouts per station；
- Modular design for quick installation and easy maintenance；
- Secure locking mechanisms for operator access and safety compliance；
- Certifications: CE, RoHS, and EAC for global compatibility.
Saipwell’s task was to design a smart, reliable node in BYD’s automation ecosystem.
Saipwell’s Solution
To meet BYD’s needs, Saipwell delivered a series of junction boxes featuring:
✅ 1. Custom 3D-Modeled Designs
Each junction box was designed based on actual production layouts, using CAD/CAM software to ensure exact positioning of terminal blocks, DIN rails, and cable entry ports.
✅ 2. Robust Enclosure Materials
The enclosures were made of powder-coated cold-rolled steel with a sealed IP66-rated structure, capable of withstanding harsh workshop environments.
✅ 3. Fast & Flexible Mounting
Support for wall-mount, bracket-mount, and profile rail installations with pre-installed mounting kits. Cable routing channels and internal plate holes were optimized for plug-and-play wiring.
Project Benefits
The deployed solution delivered the following improvements:
- Installation time reduced
- Maintenance intervals significantly extended
- BYD’s engineering team praised the solution as “compact, easy to install, and highly maintainable”
This collaboration not only marks a successful implementation but also strengthens the partnership between Saipwell and major players in the EV industry, paving the way for expanded cooperation in power management and smart infrastructure.
Conclusion
Through this project, Saipwell demonstrated its ability to provide tailored, high-performance enclosure systems for demanding industrial applications. The successful deployment at BYD’s intelligent factory showcases the core values of speed, flexibility, and reliability that define Saipwell’s approach to global manufacturing partnerships.
