Jiangmen Dongji Intelligent Equipment Co., Ltd.

Jiangmen Dongji Intelligent Equipment Co., Ltd. (Dongji Intelligent) is a Chinese contract manufacturer specializing in precision sheet metal fabrication and the OEM/ODM development of smart hardware and self-service terminal equipment. Established in 2011, the company operates from an integrated facility in Jiangmen, Guangdong, which it describes as a 30,000 m² Industry 4.0 smart factory (with some pages citing a 38,000 m² plant). Dongji positions itself as a vertically integrated partner that takes projects from design and prototyping through laser cutting, CNC punching and bending, welding, surface treatment, cabinet and electrical assembly, testing, and packing — all performed in-house. The company's service portfolio spans custom sheet metal fabrication, high-precision laser cutting, CNC bending, robotic welding, powder coating, product development, and full contract manufacturing. Its flagship OEM/ODM offering is smart terminal equipment, including vending machines, smart lockers, and integrated hardware systems. Dongji highlights proprietary technology such as an auto-peeling mechanism for fresh-orange juicing vending machines and an IoT cloud platform for remote fleet management of vending operations. It reports holding 100+ technical patents and serving clients across more than 10 countries, with export activity reaching 50+ markets according to its services page. Dongji markets itself on measurable quality and precision, citing ISO9001, CE, FCC, and UL certifications, a three-stage quality control process, 100% inspection coverage, and a 99.6% first-pass yield. Its stated manufacturing tolerances include ±0.1 mm accuracy in laser cutting and bending operations, with capabilities for mild steel up to 30 mm and stainless steel or aluminum up to 20 mm. The company serves demanding sectors such as data center solutions, EV charging, medical equipment, food and beverage, renewable energy, and heavy-duty equipment. As a private Chinese manufacturer, Dongji is not publicly listed and does not disclose a parent company or ownership group in the available evidence. Its brand identity centers on being a single-source engineering and production partner for global brands seeking complex metal components and market-ready smart devices.

Jiangmen Dongji Intelligent Equipment Co., Ltd. was established in 2011, according to its official website. The company began as a small precision sheet metal workshop of approximately 2,000 m² with just 10 employees. From these origins, it grew into a vertically integrated manufacturer of smart equipment and sheet metal components. Over the following decade, Dongji expanded its capabilities and facilities. By its own account, it evolved from a basic fabrication shop into a provider of OEM, ODM, and JDM (joint development manufacturing) solutions. The company invested in a larger integrated facility in Jiangmen, Guangdong, which it now describes as a 30,000 m² Industry 4.0 smart factory; a services page cites a 38,000 m² plant. This facility houses ten in-house production stages: design, laser cutting, CNC punching, CNC bending, welding and polishing, surface treatment, cabinet assembly, electrical assembly, testing, and packing. Dongji developed proprietary technology for its smart terminal products. Notably, it introduced an auto-peeling mechanism for fresh-orange juicing vending machines, which separates the peel before extraction to avoid bitterness and pesticide residue. It also built an IoT cloud platform for remote management of vending machine fleets. The company reports holding 100+ technical patents and serving clients in more than 10 countries, with export activity reaching 50+ markets. It has obtained ISO9001, CE, FCC, and UL certifications. As of the available evidence, Dongji remains a private company with no disclosed parent or ownership group.
