Customer Background
The customer is a metal fabrication manufacturer operating multiple high-power laser cutting machines for sheet metal processing. Operators frequently access the cutting area for material loading, unloading, and inspection, which introduces potential safety risks due to high-speed motion and exposure to lasers.
The customer required a safeguarding solution that could effectively protect operators while maintaining a smooth workflow and fast cycle times, without relying solely on physical guarding or full enclosure systems.
Safety Solution with DK-QT Series Safety Light Curtains
After evaluating the machine layout and risk assessment requirements, the customer selected DADISICK DK-QT Series safety light curtains to protect the access openings of the laser cutting cell.
The DK-QT Series safety light curtains were installed at the operator access points to detect any intrusion into the hazardous zone. When an operator enters the protected area, the system immediately sends a stop signal to the laser and motion control system, preventing potential injury.
Key reasons for choosing the DK-QT Series included reliable detection performance, stable operation in industrial environments, and easy integration with the existing safety control system. The solution ensured continuous protection without restricting visibility or material handling efficiency.
Results and Conclusion
After implementation, the laser cutting machines achieved a higher level of operational safety while maintaining production efficiency. The safety light curtain solution provided real-time protection during machine operation and reduced the risk of accidents caused by unintended access to the cutting area.
The customer also benefited from improved compliance with machine safety standards and a more flexible safeguarding design compared to traditional mechanical barriers. Overall, the DK-QT Series safety light curtains proved to be an effective and practical solution for laser cutting machine safety applications.
Customer Feedback
"Since installing the DADISICK DK-QT Series safety light curtains on our laser cutting machines, we have seen a tangible improvement in both safety and productivity. The system instantly stops laser motion when an operator enters the danger zone, and has reduced downtime due to safety trips compared to physical gating alone. The integration was straightforward, and documentation met our compliance needs."
