Rooted in Foundational Smart Manufacturing, the Hydraulic Industry Embarks on a New Journey toward High-end Intelligence

The hydraulic industry is a core foundational sector of equipment manufacturing, known as the "power heart" of industrial equipment. As a key technology for mechanical transmission and control, hydraulic systems feature unique advantages including high power density, smooth transmission, precise control and reliable overload protection. Widely applied in industrial production, infrastructure construction, resource exploitation, high-end manufacturing and many other fields, they serve as an important benchmark for measuring a country’s equipment manufacturing level and industrial supporting capacity, and play an irreplaceable supporting role in the development of the real economy.

Looking at the overall industrial trend, China’s hydraulic industry, after years of accumulation, has achieved leapfrog growth from catching up from scratch, domestic substitution to large-scale development. In recent years, driven by improved domestic infrastructure, renewal of construction machinery, popularization of agricultural mechanization and upgrading of industrial automation, market demand for hydraulic products has maintained steady growth. Construction machinery remains the largest application scenario for the hydraulic industry; the core power systems of excavators, loaders, cranes and other equipment are highly reliant on hydraulic technology. Meanwhile, expanded applications in mining machinery, injection molding equipment, metallurgical machinery, aerospace and new-energy equipment continue to broaden the market boundary and drive steady expansion of the industry scale.

In terms of technological innovation, the traditional hydraulic industry is completely shedding its label of "extensive, high-consumption and low-efficiency" development and undergoing comprehensive transformation toward intelligence, energy conservation, integration and precision. In the past, domestic hydraulic products suffered from insufficient precision, high energy consumption and poor durability, and high-end hydraulic components relied heavily on imports. Today, domestic enterprises keep increasing R&D investment and making continuous breakthroughs in core technologies such as electro-hydraulic proportional control, servo hydraulics, intelligent sensing monitoring and energy-saving hydraulic systems. Integrating the Internet of Things and big data, intelligent hydraulic systems enable real-time monitoring of equipment operating status, automatic fault early warning and accurate parameter adjustment, greatly improving operational efficiency and safety to meet the core demands of modern industrial intelligent manufacturing.

Green low-carbon development and domestic substitution have become the two core themes for the hydraulic industry at present. Guided by the "Dual Carbon" goals, green products such as energy-saving hydraulic pumps, low-leakage hydraulic valves and lightweight integrated hydraulic units have gained rapid popularity. They effectively cut equipment energy consumption and pollutant emissions, facilitating the green transformation and upgrading of industries. At the same time, leveraging China’s complete industrial chain supporting advantages, domestic hydraulic brands, after full substitution in the mid-to-low-end market, are continuously tackling technical barriers for high-end hydraulic components. They are gradually breaking the monopoly of foreign brands in high-end equipment and precision hydraulic systems, with the localization rate rising steadily.

Nevertheless, the industry still faces some shortcomings. Insufficient R&D capacity for high-end core components, immature precision machining processes, fierce homogeneous competition and shortages of high-end technical talents remain key bottlenecks restricting the high-quality development of the industry. Going forward, the hydraulic industry must keep focusing on technological innovation, delve into precision manufacturing, strengthen in-depth industry-university-research integration and break through core technical bottlenecks. In addition, enterprises should abandon low-price competition, focus on segmented markets and build competitive edges featuring specialization, high-end positioning and branding.

In summary, as a cornerstone industry of industrial manufacturing, the hydraulic industry boasts broad development potential. Supported by multiple dividends from intelligent manufacturing, green manufacturing and domestic substitution, China’s hydraulic industry will continue to realize technological upgrading and industrial iteration, transforming from a basic supporting industry into a high-end core intelligent manufacturing sector, and continuously inject strong momentum into the high-quality development of China’s equipment manufacturing industry.
