How to Determine the Right Tonnage for Your Servo Press

9 Key Factors In Selecting A Servo Press

What is Tonnage?

Tonnage measures the maximum force a servo press can exert, it is critical for tasks like stamping, bending, or deep drawing.

Key Considerations:

Material & Thickness: Harder materials (e.g., steel) or thicker sheets demand higher tonnage. For example, punching a 10mm steel plate may require 100-150 tons.


Force Calculations: Use material-specific tonnage charts or engineering formulas. Always add a 20-30% safety margin to avoid overloading.


Servo Advantage: Unlike traditional presses, servo models offer dynamic force control, adjusting tonnage mid-stroke for precision.

Top Applications of Servo Presses in Manufacturing

Servo presses shine in industries requiring accuracy and flexibility. Popular uses include:

 

Precision Forming: Electronics, automotive, and aerospace parts (e.g., battery housings, connectors).


High-Speed Stamping: Ideal for metal components like brackets or panels.


Deep Drawing: Complex shapes such as automotive body parts or cookware.


Assembly Tasks: Press-fitting bearings or fasteners with controlled force.

Why Servo presses?

±0.01mm accuracy for tight tolerances.
Programmable motion profiles handle multiple tasks in one cycle.
Energy savings of up to 50% compared to hydraulic presses.

Stroke Length & Speed: Matching Your Production Needs

Stroke Length: Ensure the ram travel suits your application. Deep drawing needs 200-300mm strokes; stamping may require 50-100mm.

Speed Control: Adjust speeds for high-volume stamping (fast) or delicate forming (slow).

Cycle Time Optimization: Servo presses reduce idle time with customizable motion profiles, boosting output.

Bed Size & Tooling Compatibility

Bed Dimensions: Confirm the press accommodates your largest die or workpiece. Measure tooling and add clearance.


Shut Height: Match the closed ram-to-bed distance to your die height.


Modular Options: Look for T-slots or customizable beds for flexible setups.

 

Smart Control Systems for Modern Manufacturing

User-Friendly Interface: Intuitive HMIs simplify programming force, speed, and position.


Real-Time Data Monitoring: Track force, displacement, and quality metrics for Industry 4.0 integration.


Recipe Storage: Save settings for quick changeovers in mixed production runs.

 

Energy Efficiency & Maintenance Benefits

Lower Power Use: Servo motors consume energy only during motion, slashing costs by 20-50%.


Reduced Maintenance: Fewer mechanical parts (no flywheels/clutches) mean less downtime.


Quieter Operation: Improved workplace safety and comfort.

 

Budgeting & ROI: Is a Servo Press Worth It?

Upfront Cost vs. Savings: Higher initial investment pays off through energy efficiency, reduced scrap, and versatility.


ROI Boosters:
Fewer defects due to precision.
One press handles multiple jobs, cutting equipment costs.
Faster setups minimize downtime.


Supplier Support: Prioritize brands offering training, spare parts, and reliable service.

Additional Tips for Choosing a Servo Press

Factory Footprint: Compact designs save floor space.
Safety Features: Ensure overload protection, emergency stops, and light curtains.
Future-Proofing: Opt for scalability to handle new materials or larger parts.
Automation Integration: Check compatibility with robots or conveyors for smart production lines.

Test Before You Invest

Consult Experts: Share specs (material, part size, volume) with suppliers for tailored advice.
Request Demos: Test the press with your dies to verify performance.

Final Thoughts

Choosing the right servo press balances tonnage, application needs, and smart features to maximize ROI.
