What Is Servo Hydraulic Press Technology in Modern Industry?

Servo hydraulic press technology combines hydraulic systems with servo motors to achieve high precision, energy efficiency, and intelligent control.

Unlike traditional hydraulic presses, servo hydraulic systems use servo motors to directly control pressure, position, and speed. As a result, manufacturers can achieve more flexible and accurate forming processes.

However, while the benefits are clear, several key technical challenges still limit the full development of servo hydraulic press systems.

Challenge 1: Closed-Loop Control of Pressure and Position in Servo Hydraulic Systems

Why Closed-Loop Control Is Critical in Servo Hydraulic Press Technology

First of all, achieving stable and precise closed-loop control is one of the biggest challenges.

In theory, adjusting the speed of the servo motor can control both hydraulic pressure and position. However, in real-world applications, this technology is not yet fully mature.

Traditional hydraulic presses rely on:

• Proportional valves
• Electro-hydraulic servo valves

These components provide stable control of pressure and position. In contrast, servo motor-driven systems require advanced control algorithms to replace these functions.

Key Technical Difficulties in Pressure Control

To be effective, the system must maintain:

• Stable pressure within a wide range (1–25 MPa)
• High precision under dynamic working conditions

Therefore, manufacturers must develop specialized algorithms that ensure both stability and responsiveness. Without this, system performance can fluctuate, especially under varying loads.

Challenge 2: Energy Recovery and Energy Management in Servo Hydraulic Press Systems

Why Energy Recovery Matters in Hydraulic Press Applications

In addition, energy efficiency is a major concern in modern manufacturing.

During operation, hydraulic presses generate recoverable energy from:

• The downward movement of the slider (potential energy)
• Pressure release in hydraulic cylinders

However, current hydraulic systems lack mature solutions to effectively capture and reuse this energy.

Energy Management Challenges in High-Power Systems

Another issue is energy distribution.

In large servo hydraulic presses:

• Peak power demand can be several times higher than average power
• Sudden power spikes can impact the electrical grid

Therefore, an efficient energy management system is essential. It must:

• Balance power usage
• Store and reuse excess energy
• Prevent grid instability

This is especially important for large-scale industrial operations.

Challenge 3: Development of Dedicated Control Systems for Servo Hydraulic Presses

Limitations of Traditional PLC Control Systems

Most conventional hydraulic presses use PLC (Programmable Logic Controller) systems. While PLCs are reliable, they are not ideal for servo hydraulic presses.

This is because servo systems require:

• Real-time pressure and speed closed-loop control
• High-speed data processing
• Complex algorithm execution

As a result, standard PLC systems often cannot meet these advanced requirements.

Why Industrial PC-Based Control Systems Are Needed

To solve this problem, many manufacturers are turning to industrial PCs.

Compared to PLCs, industrial PCs offer:

• Higher computing power
• Better flexibility for algorithm development
• Improved system integration

However, this also means that companies must develop custom control systems tailored to servo hydraulic applications.
