Customer Background
Metal stamping presses are widely used in manufacturing industries for forming, punching, and shaping metal parts. These machines operate with high force and fast cycle times, making operator safety a critical concern—especially in production environments where manual loading and unloading are required.
In this project, the customer operates a workshop equipped with multiple mechanical stamping presses arranged in a continuous production layout. Operators manually feed metal sheets into the press area, creating a high-risk zone at the point of operation where injuries can occur if adequate safety measures are not in place.
Safety Challenges
The main safety challenges faced by the customer included:
· Direct operator access to the die area during each production cycle
· High-speed press movement with severe crush and pinch hazards
· The need to maintain productivity without slowing down the press operation
· Limited feasibility of physical guards due to frequent material handling
The customer required a safety solution that could reliably protect operators while allowing efficient and uninterrupted stamping operations.
Dadisick Safety Light Curtain Solution
Dadisick safety light curtains were installed at the front access area of each stamping press to protect the hazardous die zone. The light curtains form an invisible infrared safety field between the operator and the press tooling. If any object—such as a hand or finger—enters the protected area during operation, the safety system immediately sends a stop signal to the press control system, preventing dangerous motion.
Key advantages of the Dadisick safety light curtain solution include:
· Fast response time suitable for high-speed stamping presses
· Reliable finger and hand detection, ensuring precise protection
· Stable operation in harsh industrial environments
· Easy integration with existing press control circuits
· Compliance with industrial machinery safety requirements
By selecting the appropriate resolution and protective height, the solution effectively minimized risk while maintaining optimal production efficiency.
Implementation Results
After implementation, the stamping workshop achieved a significant improvement in workplace safety. Operators can now perform loading and unloading tasks with confidence, knowing that hazardous motion is automatically stopped when the safety field is interrupted.
The customer reported:
· Reduced risk of hand and finger injuries
· Improved compliance with safety regulations
· Minimal impact on press cycle time
· Higher operator confidence and productivity
Customer Feedback
"As the Production Supervisor of our metal stamping workshop, operator safety is always our top priority.
After installing Dadisick safety light curtains on our stamping presses, we significantly reduced safety risks without affecting production efficiency. The response time is fast, the system is stable, and it integrates perfectly with our existing machines. This solution has greatly improved both safety and operational reliability."
