Shenzhen Sandai Robot Co., Ltd. is a professional industrial automation enterprise specializing in the development and manufacturing of welding robot arms, robotic welding systems, and intelligent welding automation solutions for global manufacturing industries. Established in 2012 and headquartered in Shenzhen, China, the company integrates advanced robotics technology, precision engineering, software development, and automated production capabilities to deliver reliable and efficient welding solutions worldwide.
Sandai Robot operates a modern manufacturing facility employing over 380 experienced technicians. With 20 automated assembly and testing lines, the company maintains strict quality control procedures throughout design, production, calibration, and final inspection processes. Serving sectors such as automotive manufacturing, metal fabrication, shipbuilding, construction machinery, aerospace, and heavy equipment, our impact is truly global.
The trajectory of collaborative robotic arms (Cobots) is moving from simple pre-programmed tasks to AI-driven autonomous decision-making. Our R&D focuses on several key technological pillars:
Why source from China's robotics hub? The advantage lies in the ecosystem density of Shenzhen. Our proximity to high-precision gear manufacturers, sensor developers, and software innovators allows for:
1. Rapid Prototyping: Reducing the time from design concept to functional prototype from months to weeks.
2. Cost Optimization: Leveraging scaled manufacturing without compromising on the quality of core components like RV reducers and harmonic drives.
3. Customization Capacity: Our 32,000 sqm facility allows us to pivot production lines for large-scale OEM/ODM requirements while maintaining ISO 9001 and CE certification standards.
Automotive & EV Production: Our robots specialize in high-precision MIG/TIG welding for aluminum battery trays and chassis components, vital for the growing Electric Vehicle market.
Aerospace & Heavy Industry: With a span reaching 1510mm and beyond, our arms handle vacuum welding and plasma cutting for large-scale aerospace components with micron-level repeatability.
Local Support & Compliance: We understand global regulatory environments. Our products adhere to ISO 10218-1/2 for industrial robot safety and are backed by a localized support network that provides technical training, remote diagnostics, and on-site maintenance across Europe, North America, and Southeast Asia.
Sandai Robot’s core product portfolio includes six-axis welding robot arms, collaborative welding robots, laser welding systems, MIG/TIG robotic welding stations, automated welding manipulators, and customized robotic integration solutions. By combining AI visual positioning, servo motion control technology, intelligent path programming, and real-time monitoring systems, Sandai Robot provides high-precision and stable welding performance for complex industrial applications.
Our collaborative robots are designed with integrated force-torque sensors and advanced collision detection algorithms, allowing them to work alongside human operators without safety cages, significantly reducing the footprint and integration costs of automation.
We utilize AI visual positioning and laser seam tracking. This allows the robotic arm to adjust its path in real-time, compensating for minor variations in workpiece placement or thermal distortion during the welding process.
Yes. Our software supports standard industrial communication protocols such as Modbus, EtherCAT, and OPC UA, facilitating seamless data exchange with Factory 4.0 management systems for real-time monitoring and predictive maintenance.
Depending on the application complexity and labor costs, most of our clients achieve full ROI within 12 to 18 months through increased throughput, reduced waste, and improved labor allocation.
