Mold damage, production delays? Atonm MDSC-8200T metal double-sheet detector protects automotive stamping lines

“Stop the line! Another double sheet!” In an automotive stamping workshop, Supervisor Zhang shouted at the operator — a newly installed mold was just damaged because double-sheet metal feed was pressed, requiring at least three days of repairs, inevitably delaying order delivery.

This is one of the most frustrating scenarios on automotive stamping lines: double sheets not only cause product scrap but can also damage expensive stamping molds, resulting in losses of tens of thousands or even hundreds of thousands of dollars.

Automotive stamping production demands continuous and stable operation, and equipment reliability directly impacts output. On stamping lines, double or multiple sheets of metal materials, such as cold-rolled or galvanized steel, are a hidden threat to mold safety and production capacity.

In addition, high-speed production lines place strict demands on detection speed, and frequent multi-mold changeovers create efficiency bottlenecks, causing headaches for many car manufacturers.

The Atonm MDSC-8200T was specifically designed to address these core challenges as a sheet overlap detection solution.

Precise Detection: Eliminating Double-Sheet Risks at the Source
The Atonm MDSC-8200T double-sheet detector integrates eddy current and magnetic induction technologies with an upgraded sheet-overlap detection algorithm. Its excellent anti-interference capability eliminates the impact of external disturbances on detection results, ensuring stable performance. The detector achieves a detection accuracy of up to 99.9%, reliably identifying ferromagnetic metal sheets such as galvanized steel or regular steel.

Ultra-Fast Response, Suited for 20SPM High-Speed Lines
High-speed production lines demand rapid detection. The MDSC-8200T features a single-head response time of ≤95 ms and a dual-head coordinated response time of ≤160 ms, achieving a detection rate of up to 200 pcs/min. This ensures timely detection on 20SPM high-speed stamping lines, maintaining continuous production and preventing delays from impacting the production rhythm.

1000 Stored Recipes, Seamless Production Changeovers
The 8200T features 1,000 built-in recipe storage slots, breaking traditional limitations. During multi-mold production changeovers, there’s no need to delete old recipes due to limited storage, improving switching efficiency by over 60%. Dual heads can independently detect different sheet thicknesses within the same recipe, allowing continuous production in dual-mold scenarios with two different material thicknesses—no back-and-forth recipe switching required.

Visualized Thickness Measurement for Optimized Process Control
The 8200T’s real-time thickness detection visually displays sheet thickness, preventing material mix-ups while recording data throughout the process. This enables quality traceability and process optimization.

What does this mean for automakers? At a leading new energy vehicle stamping plant, the production manager calculated:

Previously, double-sheet issues caused at least two mold repairs per month, each costing over ¥50,000. Combined with scrap and downtime, monthly losses approached ¥100,000. After switching to the 8200T, there were no mold damages for six months. Changeovers no longer required manually deleting recipes, reducing changeover time from 20 minutes to under 8 minutes. Rework caused by incorrect materials dropped 90%, saving over ¥80,000 per month, while production capacity increased by 15%.

For automakers, this translates into real, tangible cost savings and productivity gains.

Flexible Integration: Even Older Lines Can Be “Upgraded”
Many automakers worry that new detection equipment might be incompatible with existing stamping lines, leading to high retrofit costs, or that modifying original system code could disrupt programs, affect PLC/MES operations, and cause production stoppages. To address these concerns, Atonm provides a “Zero-Risk Code Upgrade Service”, solving integration challenges at the source and allowing companies without in-house technical teams to safely replace equipment.

The service strictly follows the principle of “No modification, no migration, no interference”. Only a dedicated interface program between the Atonm device and the existing system is developed, without touching any running original code. This eliminates the risk of program errors due to code changes, ensuring production line safety. After the upgrade, complete interface documentation (including code comments and logic explanations) and technical training are provided. Even without a professional technical team, companies can fully understand the integration logic and manage future maintenance independently.

“Our old stamping lines were all equipped with imported double-sheet detectors. For this line upgrade, we were concerned about cost and whether domestic equipment would integrate as smoothly. After the Atonm team inspected three lines, they provided a professional replacement plan and even helped configure the PLC integration. Once installed, it worked immediately. Our operators learned in just 10 minutes, and the cost-performance ratio is much higher than imported devices.”

This feedback from a procurement manager at a joint-venture automaker reflects the experience of many in the industry.
