--- Customized Solutions for Global Clients ---
• Tailored Designs to Meet Specific Needs:
Guangdong Dongji Intelligent Device Co., Ltd. excels in delivering fully customized sheet metal solutions that align with unique client requirements across industries. One standout example is our collaboration with FRANKE, a leading European kitchen appliance brand, where we designed and fabricated stainless steel enclosures for their premium smart kitchen units.

We implemented a dedicated process combining automatic grinding for regular shapes and manual polishing for complex geometries, ensuring flawless aesthetics and durability. Another case involved working with NVIDIA to develop specialized robot enclosures for AI-powered industrial systems. These enclosures had to withstand high thermal loads, electromagnetic interference, and harsh environments, so we used CNC-bent stainless steel with integrated heat dissipation fins and EMI shielding layers. The final product passed rigorous environmental testing and was deployed in multiple data centers globally. Additionally, we partnered with Future Pig Farm (FPF) to create custom animal self-feeding equipment with weatherproof enclosures and tamper-proof locking mechanisms. Each solution was engineered based on site-specific conditions, demonstrating our commitment to adaptability and client-centric innovation. Whether it’s a compact grid cabinet for retail or a heavy-duty power exchange cabinet for energy infrastructure, our design team works closely with clients from concept to completion, leveraging CAD modeling, simulation tools, and rapid prototyping to minimize revisions and accelerate time-to-market.

• Stringent Quality Control Processes:
Quality is embedded in every phase of our operations at Guangdong Dongji Intelligent Device Co., Ltd. Our ISO9001:2015-certified quality management system follows a rigorous four-stage inspection process: Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Final Quality Control (FQC), and Outgoing Quality Control (OQC). Every batch undergoes comprehensive checks using advanced equipment such as 2D image measuring instruments (accuracy: 2μm), tensile testers, hardness testers, colorimeters, and salt spray test chambers. For example, during the production of a batch of refrigerated vending machines for a U.S.-based client, our FQC team detected a minor dimensional deviation in a critical weld joint. Thanks to our real-time MES system, the issue was flagged immediately, and corrective action was taken before shipment—preventing potential field failures. We also utilize an automatic sheet metal parts detection system to verify dimensions and surface integrity, reducing human error by over 70%. Our internal lab includes noise meters, thickness gauges, and torque testers to validate functional performance. All products are tested under simulated real-world conditions, including vibration, humidity, and extreme temperatures. This proactive approach has earned us recognition as an Audited Supplier by major brands like Watson, BYD, and Senao. Moreover, our 5-year coating warranty—backed by our phosphorus-free powder coating process—demonstrates our long-term confidence in product durability.
