Solutions & services
A new factory. An evolving vehicle platform. A line that needs to work differently. Connect planning, equipment and automation around your production requirements.
Start with your production challenge
Choose a complete line or a focused engineering service. The starting point is the same: the vehicle, the process and the conditions on your factory floor.
Connect factory planning with equipment design, manufacturing and commissioning.
02Examine layouts, model changes and equipment that must fit a specific operation.
03Bring material handling and production-system interfaces into the same conversation.
Our engineering capabilities
Explore each service to understand its scope, the engineering questions involved and relevant project experience.

Connect factory planning, equipment design and manufacturing with installation and commissioning. Build the line around the vehicle, the process and the production target.
Explore solution
Bring process plans, equipment positions, people and material movement into one factory layout. Use simulation to examine the line before physical installation.
Explore solution
Adapt production equipment to a specific vehicle, operation or factory constraint. Start with what the workpiece needs to do, then define the equipment around it.
Explore solution
Connect storage, conveying, sorting and information systems around the flow of materials. Bring the right handling equipment into the production process.
Explore solution
Bring digital-twin visualization, automated guided vehicle (AGV) transport and production information together. Define digital capabilities around the decisions your factory needs to make.
Explore solution
Bring vehicle inspection stations into the final-assembly flow. Explore the alignment, lighting, speed, axle-load and braking equipment described in DUOYUAN's testing-line offering.
Explore solutionThe complete-line perspective
Planning, equipment and controls affect one another. DUOYUAN's complete-line project experience spans design, manufacturing, installation and commissioning.
Organize the layout, process sequence and equipment around the vehicle and its assembly requirements.
Bring mechanical design, automation and material handling into a coordinated production system.
Connect equipment manufacturing with the interfaces between stations, conveyors and controls.
Bring the line together on site and address equipment operation and process coordination.
Project experience
Complete lines, tailored handling and production data: three different scopes from DUOYUAN's project portfolio.
Project experience Production line design & manufacturing
For Qingdao Meijin, DUOYUAN's project scope covered the design, manufacturing, installation and commissioning of the complete assembly line.
