1. The role of hydraulic industry in national economic construction

Hydraulic components are power components, control components, actuating components, auxiliary components and other components used in hydraulic systems. There are many kinds of hydraulic parts, which are widely used in four column hydraulic press, gantry hydraulic press, agricultural machinery, metallurgical mining machinery, plastic machinery and other industries.

As the key technology of transmission and control, hydraulic technology is the core technology and basic technology that widely used in the industrial field. The United States, Japan, Germany and other industrial powers are undoubtedly gantry straightening press super powers. The four column hydraulic press machine technology is becoming more and more sophisticated as well as more and more perfect. The hydraulic industry has formed a huge industry and specialized science. Over the years, the "three basics" (basic parts, basic materials, and basic processes) have become the weakness of China's machinery industry. High end hydraulic components have been imported for a long time. Hydraulic technology has become a weak point in China's equipment manufacturing industry, and is known as the "pain of locking the throat" in the industry.

It is the advent and development of hydraulic technology that has promoted the equipment manufacturing industry and other fields to continuously improve their performance and level. Without the application and development of hydraulic technology, the equipment manufacturing industry would not have such rapid development today. China, as a big manufacturing country, should pay more attention to it. Therefore, in order to become a truly powerful manufacturing country in the world, China must also become a powerful country in the embossing press industry. This is a historical choice, as well as an opportunity and challenge for the development of China's equipment manufacturing industry.

2. Overall situation of China's hydraulic industry
Over the past 30 years since the reform and opening up, China's hydraulic industry enterprises have become the important cornerstone of the equipment manufacturing industry and the basic industry of the machinery industry through technology introduction, digestion, absorption and re creation, and many times of technological transformation and process reengineering, and have made remarkable achievements in supporting major national projects and key projects. China's hydraulic products have been successfully equipped with a variety of key models of military aircraft, naval ships, main battle tanks of the army, armored personnel carriers, Shen-5, Shen-6 spaceships in the aerospace field, Chang'e Project and other major equipment.

It is not difficult to see that in order to become a powerful hydraulic technology country and shorten the gap with the international advanced countries, China must rapidly improve the productivity level of hydraulic industry enterprises, break through the bottleneck of hydraulic components with high performance and reliability, so as to drive the overall revitalization of the equipment manufacturing industry.

However, China's hydraulic industry has a short history of development and low industrial concentration. Most enterprises are small in scale and lack independent innovation capability. Most hydraulic products are at the middle and low end of the value chain. R&D investment accounts for less than 3% of sales. Product concentration and brand influence are weak. According to the statistics of the Hydraulic and Gas Tightness Association, at present, there are more than 1000 domestic hydraulic enterprises, including more than 300 enterprises above designated size and more than 100 major enterprises.

The market share of the top four enterprises in the industry is only about 10%. The industry concentration is low. Most enterprises have small capacity. There are few enterprises with high-end products and high technical capabilities, which restricts the improvement of the overall technical level of China's hydraulic industry, Nor can it meet the rapidly growing domestic market demand.
There is a classic saying in the domestic hydraulic industry: "The one who gets the forging gets the hydraulic pressure, and the one who gets the hydraulic pressure gets the world." The categories of hydraulic components are complex, and almost no hydraulic enterprise in China can produce all kinds of hydraulic components. The manufacturing of high-end hydraulic devices is very difficult, and professionals are scarce.

In recent years, the country has successively released the 13th Five Year Development Plan for the Hydraulic and Pneumatic Seal Industry, the Development Plan for Intelligent Manufacturing and the Made in China 2025, focusing on China's centralized advantages, improving product quality, and accelerating the pace of replacing high-end imported products and the intelligent process. The 13th Five Year Plan for the Development of Hydraulic and Pneumatic Sealing Industry clearly points out that during the 13th Five Year Plan period, the annual growth of hydraulic sales in China will not be less than 6%, reaching 66.9 billion yuan by 2020. More than 60% of high-end hydraulic components and systems will achieve independent guarantee.

The situation of being constrained by others will gradually ease, and the urgently needed hydraulic components and systems in the equipment industry will be widely promoted and applied. The policy continued to make efforts to promote the development of China's high-end hydraulic parts industry.
