Sany Group’s customized engine fully automated laser marking workstation recently delivered

Hours

We recently tested and delivered a customized laser marking prototype for an industry. The customer is the Sany Group, a world leader in technology, reputation and size in the construction equipment industry. Due to its high level of automation and financial strength, the customer wanted to mark the top and sides of a cast aluminum engine block in the shortest possible time while using robotic loading and unloading.

Based on considerations of minimizing handling and adjusting the position and angle of the engine, and after technical and process discussions, the customer ultimately selected a dual-fiber marking workstation that uses two 100W MOPA fiber autofocus lasers to scan for high-contrast, deep marking of the two workspaces, and a high-speed servo motor motion module to clear the robot load/unload workspace by resetting the position. A full marking cycle time of approximately 15 seconds for a single motor has been tested to mark dark gray areas to a depth of approximately 0.2 mm without burning or yellowing.

Reduce any movement of workpieces.

Our factory is highly automatic and intelligent, you’d better reduce the movement and interaction of workpiece as little as possible, and we have infinite amount of robot can do loading and unloading. “

Reduce any adjustment for speed up.

Many suppliers like your company have recommended the use of rotary fixture and autofocus marking system, but the manual fixing of motor and gas cylinder clamp is still slow. We plan to integrate the marking process into the current production line and make it as fast as possible. The short term target is marking in 10 seconds and the whole process with loading and unloading in 30 seconds, the long term target is the whole process under 15 seconds. Give us your best configuration with TWO or THREE lasers that can do the job in time and achieve 0.2mm marking depth, high visibility and no burn.”

Is it enough?

We do care about the production period rather than the economic, you recommended two 100W laser for this process, are they enough? We need ONE marking time to achieve 0.2mm depth and looks well? Can you send a test mark video and sample to us? With 100W, 200W, 300W and 500W, and the price of each laser source.”

After several times of marking test, the customer finally chooses 100W JPT M7 lasers with 95% power setting for the job. The 200W or more powerful lasers need to set the output around 140~150W, which is marking a little better, but cost much higher for the system.

If you are finding integrated laser solution in line, contact us and ask for a sample marking.

Application Context for Sany Group's customized engine fully automated laser marking workstation recently delivered

This page is part of CNMarking’s Laser cleaning content library. For buyers comparing similar equipment, the key question is not only whether the sample can be marked, cleaned, welded, or processed, but also whether the final setup can match production speed, fixture stability, marking depth, visual quality, and long-term maintenance requirements. The application is most relevant to rust removal, paint stripping, oxide removal, weld mark treatment, mold maintenance, and controlled surface cleaning before production.

When evaluating a similar project, CNMarking normally checks the workpiece material, available marking area, expected cycle time, required code or logo content, fixture method, safety enclosure needs, and whether the process must connect with an existing line, MES, scanner, or operator workflow. These details help choose between a standard machine, a semi-custom workstation, or a fully automated solution.

How to Choose a Similar Setup

  • Send clear photos or drawings of the workpiece, including the required marking or processing position.
  • Confirm the material, surface coating, required depth or contrast, and any durability requirements after cleaning, painting, heat treatment, or outdoor use.
  • Share the expected production rhythm, such as pieces per hour, operator loading method, fixture constraints, and whether automatic code reading is required.
  • For new applications, request sample testing first so the marking quality, processing speed, and fixture plan can be confirmed before mass production.

FAQ

Can CNMarking test my own samples before quotation?

Yes. For most marking, cleaning, welding, and precision laser processing projects, sample testing is the safest way to confirm process feasibility. A short video, test photos, and recommended configuration can be prepared after the workpiece and target result are confirmed.

What information should I send for a faster recommendation?

Please send the material, dimensions, required content, target cycle time, production environment, and any automation requirements. If the project is replacing an existing process, also share the current pain point, such as low efficiency, unstable quality, consumable cost, surface damage, or traceability requirements.
