Product Features

1. Attractive and Outstanding Appearance

Our hydraulic press for PHE plateforming, designed by Shanghai Empire Mechanical Engineering Co., Ltd., features an attractive and compact structure based on humanized principles.

2. Wire Wound Frame

The pre-stressed wire wound frame of our hydraulic press allows for an enlarged pre-load margin, ensuring no slits between the pillar and semicircular beam during operation. The steel wire used in the frame is durable and can be used for long-term purposes.

3. Durable Main Cylinder

a) The cylinder of our hydraulic press is designed with scientific and rational wall thickness based on finite element design calculations. The wire wound construction allows for resilient deformation within a tiny range at rated pressure, ensuring the major seal works without gaps.

b) The hydraulic press uses a bronze guide seal instead of a plastic nylon guide seal, resulting in a smooth inner wall of the cylinder. This prolongs the life of the main cylinder and the main seal simultaneously.

4. High Strength and Rigid Oriented System

The oriented system of our hydraulic press adopts four rigid cylindrical guide posts that are specially plated and grinded. This ensures a well-distributed oriented gap and smooth operation of the oriented worktable with high precision. The worktable remains parallel, resulting in even corrugation depth and compliance with high international standards.

5. Patented Direct Oil Charging Structure

The oil charging path of our hydraulic press features a simple structure, small resistance, and excellent oil charging performance. This improves energy efficiency and operation speed, ultimately increasing production efficiency for users.

6. Patent Pending Epitaxial Oil Charging Valve

Our hydraulic press utilizes a special epitaxial oil charging valve to prevent potential damage caused by pressure differential when the pressure is relieved. This valve offers advantages such as a smaller size, longer operating life, and higher efficiency compared to other products.

7. Outstanding Pressing Capability

The wire wound frame of our hydraulic press ensures each wire bears equal stretch force throughout the plate pressing process. This allows our hydraulic press to achieve plate pressing with lower pressure (10% to 15% less) compared to other competitors. It is also capable of forming larger plates using the same pressure as others, resulting in less pressure loss.

8. Rapid Pressing with Reasonable Speed Forming

Unlike traditional machines with direct pressing speeds of 0.2 to 0.5 mm/s, our hydraulic press for PHE makes a breakthrough. It achieves an initial plate pressing speed of 1 to 1.5 mm/s, followed by a reasonable forming speed. This innovative combination significantly improves pressing speed, plate quality, energy conservation, and operating efficiency.

9. Patented Movable Worktable

Our latest hydraulic press is equipped with a specially designed movable worktable that can move in and out automatically without any auxiliary devices. This worktable maximizes operating efficiency and minimizes time and labor intensity, eliminating the need for traditional loading and unloading devices.

10. Patent Pending Three-stage Combination Pressure Relief System

Our hydraulic press features a patent pending three-stage combination pressure relief system, ensuring safe and efficient operation.

Empire Mechanical Engineering Co. Ltd - Plate Heat Exchanger

Empire Mechanical Engineering Co. Ltd, a leading Chinese manufacturer of high-quality plate heat exchangers (PHE) and hydraulics, is renowned for its exceptional reputation in the industry. With a strong focus on research and development, design, production, and sales, Empire has continuously improved its core manufacturing capabilities.

In June 2015, Empire achieved a significant milestone by successfully designing and producing the largest hydraulic press in China - a 40,000-ton hydraulic press. This groundbreaking achievement reaffirmed Empire's position as an industry leader. The 40,000-ton hydraulic press offers several advantages over lower tonnage presses, including:

• The ability to mold larger plates, with a maximum size of 4.0, meeting the requirements of high-tech industries such as nuclear power.


• Enhanced efficiency, saving one-third of the time compared to a 20,000-ton press when pressing a plate. Additionally, the 40,000-ton press allows for simultaneous pressing of multiple plates within the worktable's limits, significantly improving overall efficiency.


• Quick and easy mold replacement, thanks to the unique design of the 40,000-ton press. A single person can replace the mold within 20 minutes, solving the challenge of mold changes and further enhancing process efficiency.

Looking ahead, Empire Mechanical Engineering Co. Ltd remains committed to increasing investments in research and development and equipment, further improving its core manufacturing capabilities. By embracing automated production and intelligence, Empire aims to lead the heat exchanger industry towards the industrial 4.0 revolution in China.
