Huachangda Intelligent Equipment Group
华昌达智能装备集团股份有限公司
A Shenzhen-listed group (300278) headquartered in Shiyan that designs, builds and commissions robotic welding lines and robotic joining cells for car makers, plus conveyors, AGVs and warehouses. It integrates robots into complete production lines rather than selling robot arms.
01 / Company
What this company supplies
A listed integrator with four business areas
Huachangda’s 2025 annual report lists four businesses: robot automation, final-assembly conveying, logistics and warehouse automation, and embodied-intelligence and consumer technology. It reports under the exchange’s rules for industrial-robot system integration. Customers named in the report include BMW, GM, Volkswagen, Volvo, Ford and Toyota, new-energy car makers such as BYD and Geely, and companies in solar, battery and logistics. [S1]
Which subsidiary builds the robot lines
The annual report states that the robot automation division consists of Shanghai DMK Automotive Equipment Manufacturing Co., Ltd. and Shandong Tianze Ruankong Technology with its Shenyang branch; warehouse automation sits with US subsidiaries and Hubei DMW, and a new-energy division covers e-drive assembly and robotic cleaning. A quotation for a welding line will normally come from one of these subsidiaries, so confirm the contracting entity, where equipment is built and who commissions on site. [S1] [S2]
02 / Products
A range with distinct purchasing tasks
Robotic body-in-white welding lines
The main products listed are flexible main-line framing, side-panel, underbody and door-and-closure welding systems, plus battery-module assembly and welding lines. The company describes mixed-model flexibility through framing, pallet-car changeover, sub-assembly changeover and tooling-change systems, and states delivered lines reach up to 65 jobs per hour with automation above 95%. [S1] [S2]
Robotic joining and closure assembly
Robotic processes listed include flow-drill screwing (FDS), self-pierce riveting (SPR), laser welding, roller hemming, vision inspection and robotic mounting of front doors, four-door hinges and tailgates. Each is a separate process with its own tooling, quality checks and consumables. [S1] [S2]
Conveying, AGV and warehouse systems
The group also supplies EMS, FDS and roller-bed conveyors, AGVs from light to heavy duty with its own dispatch system, and automated warehouses with stacker cranes, shuttles and robotic palletizing. These often meet a welding or assembly line at its ends and are scoped in the same project. [S1] [S2]
Published in this directory
Start the technical discussion from the product families below, and ask for the data sheet of the exact model you want to compare.
Robotic processes and the questions each raises [S1] [S2]
| Item | Published statement | Detail to keep with it |
|---|---|---|
| Spot-weld framing and sub-assembly | Flexible framing, pallet and tooling changeover | Model mix, changeover time, geometry check method and JPH at each mix. |
| Self-pierce riveting / flow-drill screwing | Robotic SPR and FDS | Material stack-ups, consumable supply, joint test plan. |
| Laser welding and roller hemming | Robotic laser welding, robotic hemming | Laser safety enclosure, seam tracking, hem quality criteria. |
| Closure mounting | Doors, hinges and tailgates fitted by robot | Gap and flush targets, measurement method, rework path. |
| Battery-module lines | Module assembly and welding lines | Cell handling, weld inspection, traceability data. |
Huachangda describes its delivered welding lines as reaching up to 65 jobs per hour with more than 95% automation. The rate for your line depends on the model mix and station design, so set it in the contract.
03 / Technical scope
How a line project is typically run
Process design and simulation
The company describes offline robot simulation and virtual commissioning, where the line layout, robot paths and control logic are tested in a digital model before equipment is built. Ask for the simulation deliverables, reach and cycle studies per station, and how changes found in simulation are tracked. [S1] [S2]
Controls standard
The company page says DMK worked with Siemens on the SICAR automotive control standard and applied it in Chinese projects. If your plant has its own controls standard, agree early which one governs PLC code, HMI screens and safety programs. [S2]
Build, install and commission
The annual report lists the full scope from process development and simulation through manufacturing, installation, commissioning and maintenance. Define in the contract where pre-acceptance happens, what runs off-site and how production ramp-up is supported. [S1]
04 / Quality
Certifications and quality
A listed company with published accounts
As a ChiNext-listed company, Huachangda publishes audited annual and half-year reports that set out its structure, subsidiaries and business lines. For a line project, ask for reference visits to comparable lines and the warranty terms of the subsidiary that will sign. [S1]
Awards and patents in 2025
The 2025 report names a China Machinery Industry Science and Technology Award (third-class invention award) for an AR-assisted production technology, and five new invention patents, 19 utility-model patents and eight software copyrights in the year. [S1]
Before ordering, ask the company to send the certificates and test reports that apply to your configuration. How these profiles are compiled.
05 / Project fit
Where to start the technical discussion
Typical projects matched to the supply scope above, with the first questions to settle for each.
New-model introduction on an existing body shop
Flexible framing and tooling changeover are aimed at adding models without new main lines. Bring the model plan and volumes so the supplier can show which stations change and which stay. [S1]
Mixed-material bodies
Where aluminium and steel are combined, SPR, FDS and laser welding replace or supplement spot welding. Ask for process trials on your material stack-ups before line design is frozen. [S1] [S2]
Line plus logistics in one scope
Because conveyors, AGVs and warehouses are offered by the same group, a single scope can cover material delivery to the line. Assign interface ownership between subsidiaries in the contract. [S1]
Turn the supply scope into a project handover
The documents and checks to agree with this company at each stage of delivery.
Simulation sign-off
Approved layout, robot reach and cycle studies and virtual-commissioning results.
Pre-acceptance
Agreed off-site run of key stations with test parts and measurement.
Site commissioning
Ramp-up to target JPH with geometry and joint quality checked over a defined period.
Documentation
Electrical and mechanical drawings, robot and PLC backups, maintenance plans and training records.
06 / Next step
A clearer brief starts with these details
- Vehicle or product models, annual volumes, model mix and target jobs per hour.
- Body or product drawings with joining methods and material stack-ups.
- Building layout, existing lines and conveyors to connect, and installation windows.
- Plant controls and safety standards, preferred robot brands and PLC platforms.
- Ask Huachangda to confirm in writing: the contracting subsidiary, where the equipment is built, the robot brands used and the target rate for your model mix.

Common buyer questions
Does Huachangda make robot arms?
Huachangda builds robot-based production lines and systems. Ask which robot brands a proposed line uses.
Which company signs a welding-line contract?
The annual report places robot automation in Shanghai DMK Automotive Equipment and Shandong Tianze Ruankong. The quotation should name the contracting entity.
