"Intelligent manufacturing" is the word that has only come up in the last two years. On May 8, 2015, the “Made in China 2025” issued by the State Council clearly put forward the “Strategy for Manufacturing a Powerful Country,” and strived to take a decade to step into a manufacturing powerhouse. Intelligent manufacturing has become the direction for future development of Chinese manufacturing. In fact, as early as 2013, Yuchai began to promote smart manufacturing projects supported by ministries and commissions such as the Ministry of Industry and Information Technology. Recently, the project named "600,000 units/year of digital heavy-duty cylinder head casting shop" passed acceptance.

Casting is the core technology

Speaking of Yuchai's casting, we must start from 2011. At the end of the year, Jia Qinglin, then a member of the Standing Committee of the Political Bureau of the Central Committee and Chairman of the National Committee of the Chinese People's Political Consultative Conference, visited Yuchai together with Guo Xuan, the party secretary of the Guangxi Zhuang Autonomous Region. At that time, I heard that Yuchai had the largest casting center in Asia and said that casting was the core technology. He said from the ordinary cans of aviation materials, he said with emotion that today it is a pity that you did not see the casting center of Yuchai.

Today, Yuchai Foundry Center has developed into one of Yuchai's most automated and intelligent manufacturing lines. Its production covers micro, light, medium and heavy-duty engines, and it is involved in everything from vermicular cast iron to other metal materials. After the completion of the foundry center, casting has become an important pusher for Yuchai to promote foreign cooperation and accelerate new product development.

In the past two years, Yuchai has developed China's first domestically-opposed horizontally opposed engine. This engine has a compact structure and precision components. In addition, YC8CL, the highest domestic electric discharge pump with the highest displacement and power in the domestic market, was launched by Yuchai. These are all based on Yuchai's own casting and other manufacturing levels.

The cylinder head casting involved in the “600,000-unit/year mid- and heavy-duty cylinder head digital casting shop” project involved in this acceptance is even more significant. The cylinder head is a key component of China's automobile, ship, power equipment and other industrial engines. It brings together the common problems of the production of complex castings. The cylinder head manufacturing level represents the technical level of the foundry industry and is one of the important indicators to measure a country's level of casting.

Mastering the core technology of casting is of great significance to Yuchai’s winning market.

What does this project bring to the user?

Yuchai will bring value to users every time it upgrades its products and enhances the media at the manufacturing level.

First of all, one of the highlights of the “600,000/year heavy-duty cylinder head digital casting shop” project is that the central control system has highly integrated the powerful functions of digital control of the Internet. It is the first digital casting intelligence with independent intellectual property rights in China. Control center. This system promotes the automation, intelligentization, and cleanliness of castings, which is conducive to the promotion of energy saving, environmental protection and sustainable development in the foundry industry, and solves the problems of casting itself.

Second, this project changed the situation of large-engine high-strength, thin-walled cylinder head castings relying on imports. The high strength of the cylinder head helps to increase the product's power. The implementation of thin-walled cylinder heads can further reduce the overall weight of the engine and reduce fuel consumption. It can be said that starting from casting is the basis for creating a super engine.

Thirdly, this project can also realize digital process design and simulation, automatic identification of material conveying system, robot automatic coring and casting automatic cleaning, automatic batching of smelting, and on-line inspection of product quality, which greatly reduces labor intensity, and at the same time, on-line inspection of product quality. It can accurately find unqualified products so as to avoid unqualified product flow to the user and allow the user to buy products with confidence.

With Yuchai’s commitment to the construction of another national intelligent demonstration project in 2015, Yuchai will further advance in the field of casting, thereby enhancing the level of manufacturing and creating more value for customers.
