PUMO Servo Electric Cylinder Presses (PUMO Servo Presses)​ serve as an advanced upgrade and replacement for traditional hydraulic and pneumatic presses. Their core advantages lie in precision control, energy efficiency, eco-friendliness, flexible production, and intelligent management.

1. Exceptional Control Precision and Stability

• Closed-loop Control:​ Utilizing servo motors coupled with high-precision ball screws, along with pressure and displacement sensors, PUMO presses achieve full closed-loop control of both force and position. Repeat positioning accuracy typically reaches ±0.01mm​ (up to ±0.005mm in high-end models), with pressure control accuracy of ±0.5% FS—far surpassing that of traditional hydraulic presses.
• Process Controllability:​ Parameters such as pressing speed, stop position, and dwell time can be precisely adjusted. This effectively prevents overload shocks, protecting workpieces—especially brittle materials or precision electronic components—from damage.
• 2. Significant Energy Efficiency and Eco-friendly Advantages
• High Efficiency:​ PUMO presses consume power only during the active pressing cycle, with near-zero power consumption during standby, eliminating the overflow losses typical of hydraulic systems. Compared to conventional hydraulic presses, comprehensive energy savings range from 30% to 80%, drastically reducing operational electricity costs.
• Clean Operation:​ Featuring an all-electric design, PUMO presses eliminate the risk of hydraulic oil leaks and contamination. They meet the stringent requirements of cleanroom environments​ (e.g., lithium battery, semiconductor, pharmaceutical) and operate at low noise levels (60–75 dB), significantly outperforming the 80–95 dB noise output of hydraulic presses.
• 3. Intelligent Quality Control and Data Traceability
• In-process Judgment:​ By acquiring real-time Pressure-Displacement (F-S) curves, the system automatically monitors the pressing process to determine product conformity instantly (e.g., detecting over/under-pressure or insufficient stroke). It triggers automatic alarms or rejects non-conforming parts, enabling 100% inline inspection​ without reliance on manual post-process sampling.
• Data Traceability:​ Pressing data (curves, parameters, results) can be stored and uploaded via interfaces (e.g., MES integration). This satisfies traceability requirements under quality standards like IATF 16949, facilitating yield analysis and process optimization.
• 4. High Flexibility and Ease of Use (Multi-function Capability)
• Flexible Manufacturing:​ Multi-stage pressing profiles (e.g., rapid approach, sensing, pressing, dwelling, return) are programmable via a touchscreen, supporting storage for hundreds of recipes. Changeovers require only selecting the program, eliminating the need for extensive die changes or mechanical limit adjustments—ideal for high-mix, low-volume production.
• Compact Design:​ Unlike bulky hydraulic power units and piping systems, PUMO presses feature a compact structure with a small footprint, making them easy to integrate into automated production lines.
• 5. Low Maintenance Costs and High Safety
• Simplified Maintenance:​ With no hydraulic oil, filters, or seals requiring regular replacement, maintenance is minimal—primarily involving periodic lubrication of screws and guides. The low failure rate results in a significantly lower Total Cost of Ownership (TCO)​ compared to hydraulic equipment.
• Enhanced Safety:​ Equipped with multiple safety mechanisms, including safety light curtains, two-hand operation controls, overload protection, and soft limits, ensuring safer operation.
