A servo-driven power press machine combines servo motion control with intelligent monitoring to improve precision, efficiency, and quality control in stamping and press-fit production.
Unlike traditional mechanical power presses, servo-driven models can integrate force-displacement monitoring, process evaluation, data storage, and industrial communication. These functions allow manufacturers to monitor each production cycle, identify defects, and improve product traceability.
Servo-driven power press machines are widely used in automotive, electronics, hardware, and precision manufacturing applications.
Servo-Driven Power Press Machine vs Traditional Mechanical Power Press
| Comparison Item | Servo-Driven Power Press | Traditional Mechanical Power Press |
| Force-displacement sampling | Real-time acquisition up to 10K/s | Usually requires external monitoring |
| Curve evaluation | Multiple evaluation windows and judgement modes | Limited process monitoring |
| Program storage | Thousands of product programs | Mainly manual parameter adjustment |
| Data traceability | Curve images, Excel, TDMS, and serial-number tracking | Limited data recording |
| Industrial communication | Ethernet, USB, RS232, and PLC integration | Mainly basic IO communication |
| Quality control | Real-time judgement and defect alarms | Usually requires offline inspection |
Key Functions of Servo-Driven Power Press Machine
1. High-Speed Force-Displacement Curve Sampling
The built-in data acquisition system collects signals from displacement and pressure sensors and generates a force-displacement curve for each pressing cycle. With sampling rates up to 10K/s, the system provides accurate and detailed process monitoring.
2. Flexible Curve Evaluation
Up to 8 evaluation windows can be set for each curve, with 16 judgement modes available for each window. Tolerance areas can be configured by numerical values or adjusted directly on the curve, including rectangular and irregular shapes.
3. Multi-Point Curve Evaluation
The system supports multiple force and displacement sensors with synchronous or asynchronous data acquisition. It can also communicate with mainstream PLC systems, making it suitable for workpieces that require multi-point pressure monitoring.
4. Data Storage and Product Traceability
Press-fit curves can be saved as images, TDMS files, or Excel data. Historical records can be searched by serial number or barcode, while yield statistics can be generated for a selected production period.
This helps manufacturers analyze defects, review production data, and maintain product traceability.
5. Thousands of User-Defined Programs
Users can create and store thousands of product programs in the controller. Programs can be selected manually or switched automatically through PLC register signals, making product changeover faster and more convenient.
6. Online Monitoring and Real-Time Judgement
The system displays the force-displacement curve in real time and allows operators to check pressure and displacement at different points on the curve.
When the curve exceeds preset limits, the system can trigger an alarm and prevent defective parts from moving to the next process.
7. Offline Data Download
Historical press-fit data can be exported through a USB flash drive or other storage devices. The data can be generated as Excel files for quality analysis, reporting, and record keeping.
8. Industrial Data Interconnection
Ethernet, USB, and RS232 interfaces support communication with mainstream PLC systems. A single communication cable can handle signal and data exchange, helping reduce wiring compared with traditional IO-based communication.
The system can also be integrated into automated production lines and MES systems.
9. Hierarchical User Management
The control system supports multiple user accounts with different access permissions. Authorized users can modify key machine parameters, while operators can be given view-only access.
This helps reduce incorrect settings and improve equipment management.
10. Barcode and QR Code Printing
The monitoring system can connect to an external printer. After a press-fit cycle passes the quality check, it can automatically print a barcode or QR code.
Users can define the code content and label format according to their traceability requirements.

How to Choose a Servo-Driven Power Press Machine?
When selecting a servo-driven power press machine, manufacturers should consider more than pressing force and stroke. Key factors include:
- Required pressing force and stroke range
- Accuracy and repeatability
- Force-displacement monitoring capability
- Data storage and traceability functions
- PLC and automation compatibility
- Technical support and after-sales service
For applications with strict quality requirements, the monitoring and data management system can be just as important as the mechanical performance of the press.
