Double-Sheet Detection Case in Hardware Stamping Line: Efficient Application of Atonm MDSC-900E

I. Project Background

A hardware manufacturing enterprise mainly engages in the production of metal parts, with the core process being iron sheet stamping and forming. Before stamping, 0.8mm-thick iron sheets need to be fed into stamping equipment via a feeder. Previously, due to the lack of a reliable double-sheet detection method, overlapping feeding of iron sheets (double or multiple sheets) often occurred, leading to stamping die damage and product scrapping. On average, equipment downtime caused by double-sheet issues reached 20 hours per month, with direct economic losses exceeding 80,000 yuan. To improve production stability and efficiency, the enterprise decided to introduce professional double-sheet detection equipment.

II. Technical Challenges

High Detection Precision Requirements: The thickness difference between a single 0.8mm iron sheet and double 1.6mm iron sheets is minimal, making it difficult for ordinary detection equipment to distinguish them accurately.

Interference from Complex Working Conditions: The production line site has a lot of oil stains and metal debris. In addition, the operation of stamping equipment generates vibration and electromagnetic interference, which poses a challenge to the stability of detection equipment.

High-Speed Detection Demand: The feeding speed of the production line reaches 80 times per minute, requiring the detection equipment to respond rapidly to avoid missed detection.

III. Solution Selection

After multiple comparisons and technical evaluations, the enterprise finally selected the Atonm Metal Double-Sheet Detector MDSC-900E.

Solution Implementation

The MDSC-900E detection head is installed next to the feeder, 15 mm from the iron sheet conveying plane, ensuring the detection area covers the entire width of the iron sheet. The output signal port of the detector is connected to the production line PLC control system. When double sheets are detected, the PLC immediately stops the feeder and triggers an audible and visual alarm.

Core Advantages Matching Project Requirements

High-precision detection: Based on advanced inductive detection principles, it can stably distinguish between single and double sheets of 0.8 mm iron.

Strong anti-interference performance: Features electromagnetic shielding design and anti-vibration structure, enabling stable operation in environments with oil stains, dust, and strong electromagnetic interference.

High-speed response: Response time is only 1 ms, fully meeting the high-speed feeding detection requirement of 80 times per minute.

IV. Application Effects

Detection Accuracy: After commissioning, the double-sheet detection system completely resolved the issue of overlapping iron sheet feeding.

Improved Production Efficiency: Equipment downtime caused by double-sheet problems dropped from 20 hours per month to less than 1 hour, increasing the monthly output of the stamping line by 12%.

Cost Savings: The frequency of mold damage was significantly reduced, cutting monthly mold repair costs by approximately 50,000 yuan and lowering overall equipment operating costs by 35%.

Conclusion

Professional double-sheet detection equipment is a key element in ensuring stable and efficient stamping production. The application of the Atonm Metal Double-Sheet Detector MDSC-900E on the 0.8 mm iron sheet hardware stamping line successfully overcame challenges in high-precision detection, anti-interference, and high-speed response, significantly improving the automation level of the production line and the economic benefits of the enterprise. This case provides a replicable solution for similar metal processing industries.
