Rivi Magnetics Metal Stamping (M-Tecs M) Magnetic Die Clamping Systems
High-Force, Fast and Safe Magnetic Die Clamping Technology for Metal Forming Presses
The M-Tecs M Metal Stamping Series developed by Rivi Magnetics is an advanced magnetic die clamping system designed for dies used in sheet metal forming, progressive die, transfer press and deep drawing applications. By completely eliminating mechanical clamping devices, these systems reduce die change times to seconds, significantly improve operator safety and substantially increase the effective productivity of presses.
Dies used in metal stamping processes are typically heavy, large in size and exposed to very high impact forces. Even under these demanding conditions, the M-Tecs M series securely and evenly fixes the die to the press platen, ensuring production continuity and high process stability.
Working Principle and Magnetic Clamping Technology
In M-Tecs M systems, the clamping force is generated by a closed-loop magnetic field created between the press platen and the die. The magnetic field is evenly distributed over the entire die surface, so the clamping force acts across the full contact area rather than at isolated points. This approach provides several important advantages:
• Reduction of local stresses within the die
• Minimization of die bending and platen deformation
• Uniform transmission of press force to the die surface
• Extended die life and more consistent part quality
The system is available with three different magnetic pole technologies:
Square pole
Long pole
Combined pole (square + long)
This flexibility enables high clamping forces for both small and very large stamping dies, while allowing maximum utilization of the press platen surface.
Technical Performance and Numerical Data
Magnetic clamping force:
Up to 105 tons/m², depending on surface conditions
Magnetic plate thickness:
47 - 55 mm, optimized for high mechanical stability
Magnetization / demagnetization time:
2 - 5 seconds
Operating temperature:
Standard up to 80 °C
Optional up to 240 °C
Energy consumption:
Practically zero
(Energy is only required during magnetization and demagnetization)
Die modification required:
None
These values demonstrate that M-Tecs M systems can operate safely under high dynamic loads in metal forming presses.
Press Performance and Production Advantages
M-Tecs M Metal Stamping systems provide the following key benefits in press operations:
• Dramatic reduction in die change times
• Minimization of press downtime
• Complete elimination of mechanical clamping elements
• No need for operators to enter the press during die change
• Significant improvement in occupational safety
• Full utilization of the press platen surface
• Noticeable increase in hourly production output
• Shorter return on investment period
These advantages are especially critical for metal forming plants with short production runs and frequent die changes.
FES - Force Evaluation System (Optional)
M-Tecs M systems can optionally be equipped with the Force Evaluation System (FES). This technology continuously monitors the press operating cycle and dynamically evaluates the adequacy of the magnetic clamping force.
With FES:
• Magnetic clamping force becomes estimated and traceable
• Risks of die separation or slippage are detected at an early stage
• Press and operator safety is maximized
• Process continuity is maintained
FES can be monitored via a touchscreen or tablet and allows remote access through an Ethernet connection.
Safety, Sensors and Certifications
M-Tecs M Metal Stamping systems are designed in full compliance with international press safety standards.
• Compliance with EN 201 and EN 289
• Performance levels according to EN 13849-1
• Die presence sensors (limit switches)
• MDS electronic die separation sensor
• Dual-channel monitoring and interlocking architecture
• CE marking and declaration of conformity
Since all clamping and unclamping operations are performed outside the press, operator safety is maximized.
