At 4ManPro^© (Elements For Manufacturing Processes) a Hann Kuen Machinery & Hardware, Co., Ltd. BRANCH OFFICE, we include Hydraulic Power Units (HPU’s) as key elements in the 4ManPro^© portfolio. This is justified by their strategic role in enabling heavy-duty automation processes that electrical or pneumatic automation cannot efficiently meet.

1. Superior Power Density

The main advantage is the inherent power density of the hydraulic drive. A hydraulic power unit (HPU) is capable of generating extremely high forces and torques in a compact space, significantly surpassing the power-to-weight ratio of electromechanical systems. This is essential for applications requiring:

• Sustained Strength:
  • Pressing, clamping, and compaction.
• Extreme Load Capacity:
  • Moving large masses or heavy handling in casting, forging, or plastic injection molding.
• System Rigidity:
  • The incompressibility of the fluid provides superior mechanical rigidity, crucial for maintaining tolerances under high-load conditions.

2. Precise Force and Torque Control

By integrating servo valves and closed-loop control, 4ManPro^© UPH’s enable force and position modulation with exceptional response dynamics. This transforms brute force into a controllable vector, which is vital for:

• Proportional Applications:
  • Precise control of speed (flow rate) and force (pressure) in critical processes, such as injection molding or thickness control.
• Performance in Harsh Environments:
  • Inherent resistance to high temperatures, mechanical shocks, and environmental contamination—common scenarios in heavy industry.

3. RELIABILITY and Extended Service Life

The robust design of hydraulic systems, with components submerged in fluid that acts as a lubricant and coolant, ensures an extended service life and lower maintenance requirements compared to equivalent mechanical or electrical systems subjected to extreme loads.

In summary, UPH’s are 4ManPro^©‘s strategic solution to provide high-energy, controllable, and durable automation ensuring the technical and economic viability of the most demanding industrial projects.

We have a choice of UPH from different companies with different capabilities and characteristics to meet the requirements for a wide range of projects.
