--- Why Choose Dongji for Sheet Metal Fabrication? ---
• State-of-the-Art Equipment and Technology:
Guangdong Dongji Intelligent Device Co., Ltd. leverages cutting-edge manufacturing technology to deliver precision-engineered sheet metal solutions. The company’s state-of-the-art facility spans over 38,000 square meters, housing a fully integrated production line equipped with German TRUMPF laser cutters, Japanese AMADA CNC punching machines, and high-precision CNC bending systems. With a processing accuracy of up to 0.1mm and speeds reaching 10 meters per minute, these machines ensure flawless results even on complex, thick-plate materials. The integration of 5 automatic welding robots enables 24/7 continuous operation, significantly improving weld consistency and reducing human error—critical for industrial applications requiring durability and reliability. Additionally, Dongji’s powder coating line uses phosphorus-free organosilane nano conversion film technology, delivering rust-proof, corrosion-resistant finishes with over five years of guaranteed quality. This level of technological sophistication isn’t just about efficiency—it’s about building trust. For example, when NVIDIA partnered with Dongji to produce custom robot enclosures, the stringent requirements for thermal stability, electromagnetic shielding, and structural integrity were met through precise laser cutting and automated welding processes. The result? A product that not only passed rigorous testing but also became a core component in AI-driven robotic systems deployed globally. By investing heavily in automation, digital twin modeling via MES and ERP systems, and real-time data monitoring, Dongji ensures every sheet metal part is manufactured with unmatched precision and traceability—making it the ideal partner for industries where failure is not an option.

• Custom Solutions for Diverse Industries:
Dongji doesn’t just fabricate sheet metal—it engineers intelligent, scalable solutions tailored to diverse sectors. From smart vending machines and industrial 3D printers to car charging piles and agricultural self-feeding equipment, the company excels at turning conceptual designs into market-ready products. One standout example is Dongji’s collaboration with FRANKE, a global leader in premium kitchen appliances. Dongji was tasked with developing stainless steel enclosures for high-end commercial kitchen units, requiring extreme precision, aesthetic refinement, and compliance with international safety standards. Using their 8K mirror polishing production line and advanced 2D image measuring instruments (OMM), Dongji achieved surface flatness within ±2μm and delivered parts with flawless finish and dimensional accuracy. Another success story involves their work with Formlabs, where Dongji provided JDM services for compact 3D printer enclosures. These required tight tolerances, EMI shielding, and modular design flexibility—all met through integrated CNC stamping, laser welding, and automated assembly lines. Beyond consumer electronics and appliances, Dongji has also supported the automotive sector by producing power exchange cabinets for BYD’s electric vehicle ecosystem. Their ability to handle everything from small-scale prototypes to mass production runs—with full ODM/OEM/JDM capabilities—makes them a one-stop solution for clients across industries. Whether you’re launching a new smart device or scaling up industrial hardware, Dongji’s end-to-end service model ensures faster time-to-market, reduced costs, and superior product performance.
• Quality Control and Assurance Processes:
At Guangdong Dongji Intelligent Device Co., Ltd., quality isn’t an afterthought—it’s embedded in every stage of production. The company operates under ISO9001:2015 and GB/T 19001-2016 standards, implementing a strict four-tier inspection process: Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Final Quality Control (FQC), and Outgoing Quality Control (OQC). Every batch undergoes rigorous testing using advanced lab equipment such as tensile testers, hardness testers, colorimeters, salt spray chambers, and noise meters. Notably, Dongji’s Sheet Metal Parts Automatic Detection System uses machine vision to perform real-time OK/NG judgment, eliminating human error during final checks. This system played a critical role in a recent project for Watson, where over 10,000 custom sheet metal enclosures for medical devices needed to meet FDA-level cleanliness and durability standards. Each unit was scanned for dimensional deviation, surface defects, and material integrity before shipment. Furthermore, Dongji’s internal R&D team continuously improves processes—such as optimizing welding parameters based on AI-driven feedback loops—to reduce rework rates by over 40%. Their commitment to excellence is validated by certifications including CE, UL, ETL, ROHS, and SGS, and they’ve earned recognition as a ‘Guangdong Special New Enterprise’ and ‘AAA Enterprise’ for quality, credit, and brand integrity. Clients like NVIDIA and Future Pig Farm rely on Dongji not only for technical capability but also for the confidence that every part meets or exceeds global benchmarks—proving that quality assurance is not just a policy, but a culture.

• Collaborations with Leading Brands:
Guangdong Dongji Intelligent Device Co., Ltd. has built its reputation on delivering exceptional results for some of the world’s most innovative brands. One of the most compelling case studies is the partnership with NVIDIA, where Dongji was selected to manufacture custom enclosures for next-generation AI robotics platforms. These enclosures had to withstand high thermal loads, support dense electronic components, and maintain electromagnetic compatibility—all while fitting into sleek, futuristic designs. Leveraging their deep expertise in CNC machining, laser cutting, and automated welding, Dongji produced over 5,000 units with zero defect rate during initial validation. The project was completed two weeks ahead of schedule, thanks to their agile project management and pre-production engineering (APQP) framework. Another landmark collaboration was with FRANKE, a top-tier European kitchen appliance manufacturer. Dongji developed stainless steel panels for high-end commercial ovens, requiring ultra-smooth 8K mirror finishes and exact alignment tolerances. Using their grinding & polishing production line and 2D image measuring instruments, Dongji achieved consistent surface quality across thousands of units—earning praise from FRANKE’s engineering team for “industrial-grade aesthetics.” Meanwhile, in the agricultural tech space, Dongji collaborated with Future Pig Farm (FPF) to design and produce intelligent animal self-feeding cabinets that operate autonomously in remote farms. These cabinets feature weatherproof enclosures, tamper-proof locks, and solar-powered systems—all fabricated using durable galvanized steel and powder-coated finishes resistant to harsh environments. The result? A 99.8% uptime rate in field trials across Southeast Asia. These stories reflect a broader trend: Dongji isn’t just a supplier; it’s a strategic innovation partner. As one client put it, ‘We didn’t just get a product—we got a solution that evolved with our business.’ With over 50 countries served and annual sales exceeding $14 million in 2024, Dongji continues to prove that excellence in sheet metal fabrication drives real-world impact.
