Custom solutions, unique manufacturing process & quality, crafted by talent.
Mr. Cai
Chairman of Dongji
Are you a trading company or a direct manufacturer?
Yes, we are a direct manufacturer. We operate a 30,000 m² state-of-the-art facility in Jiangmen, Guangdong, backed by 14 years of manufacturing excellence. We provide true end-to-end, one-stop solutions from raw sheet metal to fully assembled smart devices.
What types of manufacturing services do you offer?
We offer highly flexible partnership models tailored to your business needs, including OEM, ODM, and JDM services. Whether you need exact manufacturing based on your designs (OEM) , ready-to-market white-label products (ODM) , or collaborative co-development for innovative smart equipment (JDM), we have you covered.
Can you manufacture custom designs based on our CAD drawings?
Absolutely. You can send us your design blueprints (such as .STEP, .IGES, .DWG) for a comprehensive evaluation. Powered by world-class equipment like German TRUMPF and Japan AMADA laser cutting machines , we maintain a strict tolerance accuracy of up to 0.1mm.
What materials and thickness ranges can your factory process?
We process a wide variety of materials, including Mild Steel, Stainless Steel, Galvanized Steel, Aluminum, Copper, and Acrylic. Our advanced machinery allows us to effortlessly handle material thicknesses ranging from 0.2mm up to 30.0mm.
Does your facility meet international quality standards?
Yes. We are an ISO9001:2015 certified manufacturer and have been fully audited and approved by SGS. Furthermore, the smart equipment we produce can be certified to meet rigorous global compliance standards, including UL, ETL, CE, FCC, and KC.
What is your Minimum Order Quantity (MOQ)? Can I order just one prototype?
Yes, it’s completely fine to order just one set for prototyping and testing. If this is your first time importing or developing smart equipment, our engineering and sales team will gladly guide you through the entire process.
What is your typical production lead time?
For standard orders under 50 sets, our production time typically varies from 15 to 30 days. For larger volumes, complex ODM/JDM projects, or customized tooling, please send us an inquiry for a precise production schedule.
What shipping methods do you recommend?
Due to the size and weight of metal enclosures and smart vending machines, we usually recommend sea freight as it is the most cost-effective option. Express or air freight is available for urgent prototypes, but it will cost significantly more. Please contact us for accurate shipping cost calculations.
What payment systems can be integrated into your smart vending machines?
We offer versatile smart payment integrations. Depending on your target market, we can equip the machines with coin acceptors, bill validators, and credit card payment systems.
How many products can I sell in one vending machine?
The internal capacity varies entirely based on your specific product dimensions and packaging. Please provide us with your product specifications, and our design team will customize the tray structure to maximize your selling capacity.
