China’s First Dual-Channel Metal Double-Sheet Detector with Thickness Measurement (9000T): An Efficiency Game-Changer for Stamping Production Lines

Guangdong — When a robot arm in the stamping shop of a joint-venture automaker picked up the 300th sheet of steel, a sharp alarm suddenly sounded. 0.2 seconds later the entire line performed an emergency stop — not due to a malfunction, but because the Atonm 9000T metal double-sheet detection system intercepted a hazard that could have caused up to RMB 200,000 in mold damage. This new-generation double-sheet detector with built-in thickness measurement has become the choice of many leading automotive manufacturers and an ideal solution for import substitution.

Eight major production-line pain points — how does 9000T solve them precisely?

High-speed automated stamping lines face multiple pain points that limit production efficiency:

- "Double-sheet feeding" raises rework costs at best and can cause mold cracking and hours of downtime at worst, with individual accident losses reaching hundreds of thousands of RMB.

- Equipment is easily interfered with under complex conditions, leading to insufficient operational stability.

- Mixed-material, dual-mode production requires frequent recipe switching; detection downtime affects continuous operation.

- High risk of loading wrong material and poor thickness traceability, resulting in coarse production management.

- Detection response lag on high-takt lines drags down overall throughput.

- Limited recipe storage forces old recipes to be deleted when switching modes.

- Incompatible communication protocols complicate integration with host systems, hindering automation upgrades.

- Sensor failures without early warning can cause double-material insertion and other safety risks.

These combined issues greatly affect line efficiency and safety.

The Atonm MDSC-9000T metal double-sheet detector addresses these pain points with a focus on "accuracy, efficiency, and reliability," leveraging electromagnetic induction and eddy-current core technologies along with multi-dimensional advantages:

- Strong anti-interference and stable performance: the 9000T uses industry-leading core technologies combined with intelligent algorithms and high-precision sensors to ensure long-term stable operation under complex conditions.

- Full-metal compatibility · multi-scenario adaptation: accurately detects stacked sheets for both ferromagnetic and non-ferromagnetic materials, fitting a wider range of applications.

- 1-to-2 dual-station, high-efficiency detection: a single probe can connect to two sensors to perform synchronized detection at two stations. Under the same recipe, the two probes can independently detect sheets of different thicknesses, eliminating recipe switches in mixed-material dual-mode production, shortening detection time, and ensuring continuous line operation.

- With thickness measurement · improved traceability and quality: built-in thickness measurement displays plate thickness in real time to prevent wrong-material loading at the source; full-process data is automatically recorded to support quality traceability and process optimization, assisting finer production management.

- Independent dual-probe settings: the two probes support independent parameter configuration, so detecting different thicknesses requires no repeated recipe switching; after disabling and re-enabling probes no re-teaching is needed, significantly improving usability and detection efficiency.

- ≤200 ms high-speed response: dual-sensor response ≤200 ms, single-sensor response as low as 120 ms, precisely matching 20 SPM high-takt lines for seamless synchronization between detection and line actions.

- 999 recipe groups stored: overcoming traditional storage limits, the system supports 999 recipe groups so switching production runs does not require deleting old recipes; one-button switching completes in seconds, improving flexibility for multi-batch small-lot scheduling.

- Intelligent communication · seamless integration: supports mainstream protocols such as IO/Profinet/EtherCat and can connect to PLCs and other host systems for centralized line control, facilitating automation upgrades.

- Modular split design: uses a modular split structure so cable maintenance does not require full-cable replacement; only the faulty segment is serviced, minimizing line downtime for maintenance.

- Safety alert · eliminate hidden risks: features sensor-disconnection alarms that proactively warn and alert when a sensor is disconnected, preventing materials from being fed while in a fault state and avoiding double-sheet insertion risks.

- Zero-risk code migration: upgrades do not touch existing PLC/MES code; paired with 72-hour testing and full technical support to ensure seamless switching between old and new equipment.

Scenario in Focus: End-to-End Protection from Destacking to Feeding

In the stamping workshop of a leading domestic new energy vehicle manufacturer, we witnessed the real-world performance of the 9000T in action:

Tailored to the characteristics of different stations, the 9000T offers customized deployment solutions:

•Flexible multi-specification production scenarios:A home appliance stamping plant needed to handle eight steel sheet thicknesses. With storage for up to 999 recipes, changeovers no longer require deleting or reconfiguring parameters, boosting monthly capacity by 8%. Independent dual-probe settings support simultaneous detection of “1.2 mm steel on the left channel + 0.8 mm aluminum on the right channel,” eliminating frequent switching steps.

•High-speed automotive parts lines:On a door panel production line running at 20 SPM, a response time of ≤200 ms ensures detection stays perfectly synchronized with feeding, preventing takt losses caused by waiting for inspection and increasing daily output by 300 parts.

•Imported equipment upgrade scenarios:When a joint-venture automaker replaced a German-brand detector, Atonm’s zero-risk code modification service enabled seamless switchover after 72 hours of testing, with no impact on normal production and a significant reduction in procurement costs.

The head of R&D at Atonm commented:
“After 18 months of research across more than 30 stamping workshops, we realized that what manufacturers truly need isn’t a pile-up of parameters, but tools that solve real operational headaches. From recipe management and thickness measurement to maintenance and upgrades, every function of the MDSC-9000T directly addresses real production line pain points—turning ‘precise detection, efficient production, and worry-free operation’ from a slogan into reality.”

For manufacturing enterprises pursuing cost reduction, efficiency improvement, and import substitution, the MDSC-9000T provides reliable protection for production line safety while driving productivity gains. If your stamping line is facing challenges in efficiency and quality control, the 9000T is a solution you can trust.
