PDH’s prestressed steel wire winding hydraulic presses are specifically engineered for ultra-high-pressure applications ranging from 40 MPa to 800 MPa, and for large-tonnage operations spanning 2,000 to 40,000 tons.

Both the machine frame and the hydraulic cylinders utilize a prestressed winding structure. This design ensures consistently low tensile stress throughout the entire assembly and eliminates stress concentrations, thereby comprehensively resolving the critical issues associated with traditional hydraulic presses—such as excessive bulk, susceptibility to cracking, short service life, and poor safety performance. The system is ideally suited to meet production demands requiring continuous heavy-duty operation, high precision, and exceptional reliability.

This hydraulic press incorporates advanced prestressed winding structure technology. It is highly suitable for a wide range of high-pressure forming processes, including cold and hot metal forming, powder metallurgy, and plastic and rubber molding. Compared to traditional structural designs, the winding structure offers distinct advantages: a compact footprint, lighter weight, the complete absence of stress concentrations, and superior fatigue resistance.

The service life of this winding structure typically exceeds 50 years. Furthermore, the immense pressure generated during the forming process is entirely contained within the wound frame structure, ensuring that no additional forces are transmitted to the ground. Consequently, the foundation requirements for this machine tool are significantly simplified, resulting in substantial cost savings.

Advantages of Pre-stressed Wire-Wound Hydraulic Presses

1. Robust Structure, Safe and Reliable

• The machine frame and main hydraulic cylinder feature multi-layer pre-stressed winding using high-strength steel wire. This ensures extremely high overall rigidity, exceptional resistance to eccentric loads, and zero deformation.
• Operating stresses are effectively counteracted by pre-compression stresses, eliminating the risk of cracking or catastrophic failure. Even in the unlikely event of a micro-crack within the inner cylinder, the machine will not fail.
• Its fatigue life far exceeds that of welded or cast-steel hydraulic presses, making it ideal for continuous, 24-hour, full-load production.

2. Ultra-High Pressure, High Tonnage, Compact Footprint

• For equivalent tonnage, the prestressed steel wire winding hydraulic press’s self-weight is only one-third to one-half that of traditional hydraulic presses. It requires minimal floor space, imposes low demands on foundation requirements, and results in significantly lower infrastructure costs.
• It supports high-tonnage, concentrated loads on relatively small table surfaces, thereby reducing investment costs for molds and equipment. It is ideally suited for precision cold forging, extrusion, and coining applications.
• Utilizing ultra-high-pressure sealing and boosting technologies, the system delivers stable pressure, rapid response times, and short pressing cycles.

3. High Efficiency, Energy Saving, Intelligent Precision

• Equipped with a servo-motor-driven pump control hydraulic system, our prestressed steel-wire-wound hydraulic press machine offers precise control over pressure and speed, saves energy, reduces noise levels, and ensures smooth operation.
• Featuring rapid fluid filling and rapid pressure relief capabilities, it boosts production efficiency by over 30% while significantly reducing energy consumption.
• Integrated with a PLC, touchscreen interface, and closed-loop control system, it allows for precise and adjustable control of pressure, displacement, and pressure-holding duration. Forming errors are kept within a tolerance of ≤0.05 mm.

4. Broad Applicability, Flexible Customization

• PDH’s prestressed wire winding hydraulic press is suitable for a wide range of applications, including precision coining, heat exchanger plate forming, wheel hub forging, powder metallurgy, titanium electrode pressing, and aerospace die forging.
• Fully customizable across all parameters—including tonnage, table dimensions, stroke length, daylight height, and automation configurations—to meet the unique and specific requirements of individual manufacturing processes.
