Customer Background
The customer is a metal components manufacturer operating multiple heavy-duty stamping presses for sheet metal forming. These presses are used in continuous production, where operators manually load and unload metal parts during each cycle. Due to the high pressing force and fast cycle time, the risk of hand injuries and accidental contact with the die area was extremely high.
Safety Challenges
Before installing safety protection, the customer faced several critical risks:
· Operators working close to moving dies
· Manual feeding inside hazardous zones
· Potential for accidental machine restart
· Difficulty balancing operator safety and production efficiency
Traditional mechanical guards limited access and reduced productivity, making them unsuitable for this application.
Dadisick Safety Light Curtain Solution
To ensure reliable operator protection without affecting workflow, Dadisick safety light curtains were installed on both sides of the stamping press opening.
Key Solution Features
· Type 4 safety light curtain
· Dual-channel OSSD outputs
· Fast response time for stamping applications
· Seamless integration with the machine's safety relay
· Compact housing suitable for harsh industrial environments
When the infrared beam is interrupted, the press immediately stops or prevents the next stroke, eliminating the risk of hand injuries.
Installation and Operation
The safety light curtains were mounted vertically at the front access area of the press, covering the entire hazardous zone.
· Any hand or object entering the die area is detected instantly
· The press cannot restart until the light curtain is cleared
· Manual reset ensures intentional restart after safety confirmation
This solution complies with ISO 13849-1 Category 4 / PL e safety architecture.
Results and Benefits
After installation, the customer achieved:
· Significantly improved operator safety
· Zero safety-related incidents on the stamping line
· Uninterrupted production efficiency
· Full compliance with internal safety audits and international standards
The safety light curtain provided effective protection without slowing down production.
Customer Feedback
