Introduction: Why Are More Manufacturers Paying Attention to Press Brake Safety?
“Can a press brake be equipped with a laser safety protection system?”
This is a question we frequently hear from customers.
In fact, in markets such as Europe and South Korea, press brake safety protection systems have long been mandatory. However, in many developing manufacturing regions, awareness of press brake safety remains relatively limited.
In this article, we’ll explore how press brake laser safety systems work, what benefits they provide, why they are required in many countries, and what practical disadvantages they may have.
Our goal is to help manufacturers make a more informed decision when evaluating press brake safety upgrades.
What Is a Press Brake Laser Safety System?
A press brake laser safety system is also commonly referred to as:
Laser safety protection device
Laser guarding system
Laser safety light curtain
Laser protection system
The operating principle is relatively simple.
One side of the system emits laser beams while the opposite side receives them.
When a hand, tool, or foreign object interrupts the laser beam, the system immediately recognizes that an object has entered the hazardous zone.
The controller then instantly disables the foot pedal signal and stops machine movement, helping prevent injury to the operator.
How Does a Laser Safety System Work?
Under normal conditions, the press brake operates as usual:
Fast approach
Automatic speed transition
Bending process
Return stroke
without affecting production.
However, if an object larger than the permitted detection threshold enters the space between the upper and lower dies, the laser beam is interrupted.
For example, if a 6 mm hex key wrench is accidentally placed in the bending area during machine operation, the safety system will immediately stop the ram movement.
Even if the foot pedal remains pressed, the machine will not continue downward.
This is one of the main reasons why laser safety systems are mandatory on many CE-compliant press brakes sold in Europe.
They significantly reduce the risk of:
Hand injuries
Operator mistakes
Accidental machine activation
New employee safety incidents
Why Are Laser Safety Systems Mandatory in Many Countries?
In many regions, laser safety protection is not considered an optional feature—it is a legal requirement.
European Market (CE Certification)
Press brakes exported to Europe must comply with CE safety standards.
These standards typically require:
Laser safety protection systems
Emergency stop systems
Dual-channel safety circuits
Without these safety features, the machine may not qualify for legal sale within the European market.
South Korean Market
South Korea also maintains strict machine safety regulations.
In many cases, press brakes without approved safety protection systems cannot be legally imported or sold.
Why Do Many Factories Still Choose Not to Install Them?
Although laser safety systems clearly improve workplace safety, adoption remains limited in some factories.
The reasons are often practical:
Additional investment cost
Reduced production efficiency
Established operating habits
Many older manufacturing facilities prioritize:
Production output
Delivery schedules
Operational convenience
over safety enhancements.
Unfortunately, accidents often occur when experienced operators become overly familiar with their work and underestimate potential risks.
Advantages of Press Brake Laser Safety Systems
1. Significantly Improved Operator Safety
This is the most important benefit.
If:
A hand accidentally enters the danger zone
A tool falls between the dies
A foreign object enters the bending area
the system immediately stops machine movement.
Compared with traditional mechanical safety devices, laser systems offer much faster response times.
The safety benefits are especially valuable for:
New employees
Trainees
Temporary workers
2. Reduced Risk of Human Error
Many press brake accidents are not caused by machine failure.
Instead, they result from:
Operator mistakes
Distractions
Workpiece misalignment
Incorrect hand positioning
Laser safety systems provide proactive protection by preventing dangerous movements before an accident occurs.
3. Ideal for High-Volume Production Environments
For factories operating:
Long production shifts
Continuous manufacturing processes
Multi-shift operations
laser protection systems can significantly reduce workplace injury risks.
As a result, they are becoming increasingly common in large manufacturing enterprises.
Disadvantages of Press Brake Laser Safety Systems
Although laser protection systems offer substantial safety benefits, they also have some limitations.
1. Reduced Production Speed
This is often the primary concern for manufacturers.
To maintain safety compliance, the machine’s:
Fast approach distance
Speed transition point
Safety monitoring zone
must typically be configured more conservatively.
As a result, the overall production cycle may become slower.
In practical applications, some manufacturers report productivity reductions of approximately:
10% to 20%
For facilities focused on maximum production throughput, this can be a significant consideration.
2. Potential False Alarms
Under certain conditions, laser safety systems may trigger unexpectedly.
Examples include:
Reflective workpiece surfaces
Edge-bending applications
Special bending angles
Complex part geometries
These situations may cause the system to interpret reflected laser signals incorrectly.
When a false alarm occurs, machine operation stops until the condition is cleared.
This can interrupt production flow.
3. Sensitivity to Material Thickness
Most laser safety systems operate within a predefined material thickness range.
If the actual workpiece exceeds the configured limit, the system may generate an alarm and stop machine operation.
For manufacturers frequently processing:
Different material thicknesses
Custom parts
Non-standard products
additional setup and adjustment may be required.
Who Should Consider Installing a Laser Safety System?
Based on practical experience, laser safety systems are particularly suitable for:
1. Factories with Many New Operators
They help reduce risks associated with operator inexperience and human error.
2. High-Volume Manufacturing Facilities
Ideal for repetitive production of standardized components over long periods.
3. Companies with Strict Safety Requirements
Examples include:
Large manufacturing groups
International companies
Export-oriented factories
Corporate facilities with formal safety programs
These organizations typically place greater emphasis on workplace safety standards.
4. Manufacturers Exporting to Europe or South Korea
In many cases, laser safety systems are required to meet local regulations and customer specifications.
Conclusion: Is a Laser Safety System Worth Installing?
The primary purpose of a press brake laser safety system is not to improve productivity.
Its true value lies in reducing the risk of serious workplace injuries.
While the system may introduce:
Slight efficiency reductions
Occasional false alarms
Additional setup requirements
these costs are generally small when compared with the consequences of a severe operator injury.
For applications involving:
New operators
Multi-shift production
High-volume manufacturing
laser safety systems can significantly improve overall workplace safety.
For many companies, installing a laser safety system is not merely an equipment upgrade—it is an important part of a comprehensive safety management strategy.
