Hydraulic press technology innovation: energy-saving equipment to help manufacturing upgrading

Recently, with the acceleration of the intelligent and green transformation of the manufacturing industry, the hydraulic press, as the core equipment in the field of metal forming, ushered in a new round of technological upgrading. A number of domestic equipment manufacturing enterprises have launched high-precision, low-energy new hydraulic presses to provide more efficient solutions for automotive, aerospace, home appliances and other industries.

Technological breakthrough: intelligent and energy-saving bright point
At the China International Industry Fair in 2024, well-known machine tool companies demonstrated the newly developed servo hydraulic press, which uses closed-loop control system and variable frequency drive technology to reduce energy consumption by more than 30% compared with traditional models. Through real-time pressure monitoring and adaptive adjustment, the equipment has achieved a breakthrough in stamping accuracy of ±0.01mm, which is especially suitable for high-end fields such as new energy battery shells and precision electronic components.

Another innovation is the integration of the Internet of Things (IoT) technology, which allows operators to remotely monitor equipment status, fault alerts and maintenance reminders from a mobile phone or tablet, significantly reducing downtime. The head of the heavy machinery plant said: "The intelligent function of the new generation of hydraulic presses has increased production efficiency by 20% and reduced labor costs by 15%."

Market demand: Automotive and new energy industries driving growth
With the explosive growth of new energy vehicles, the demand for lightweight bodies and battery components has surged, and the high stability and large tonnage advantages of hydraulic presses (200-5000 tons) have become a key link in the production line. According to statistics, the market size of China's hydraulic press in 2023 has exceeded 5 billion yuan, and it is expected to exceed 6.5 billion yuan in 2025, with a compound annual growth rate of 8.3%.

In addition, the demand for environmentally friendly equipment in overseas markets also brings opportunities for Chinese companies. For example, the oil-electric hybrid hydraulic press exported by Jiangsu enterprises to Southeast Asia has obtained the EU CE certification by recycling braking energy and optimizing the hydraulic system, and the order volume has increased by 40% year-on-year.

Industry challenge: Talent and technical barriers to be broken
Despite the broad prospects, the industry still faces problems such as dependence on imports of high-end hydraulic components and shortage of composite technical talents. Experts called for strengthening cooperation between schools and enterprises to train talents in the cross-cutting fields of machinery, automation and material science, while encouraging the research and development of domestic core components to reduce production costs.

The technical iteration of hydraulic presses is promoting the manufacturing industry to precision and green. In the future, with the deep integration of artificial intelligence and digital twin technology, this traditional equipment is expected to be revitalized in the wave of "Industry 4.0".
