Weichai Linde hydraulic Weifang localization manufacturing benchmarking Germany

Regarding the wonderful stories made in Germany, Wang Jian heard many times when he went to college. After graduating from university, he entered the work of Weichai Holding Group for eight years. His feelings about the world-famous German manufacturing are getting deeper and deeper.

“The design principle of the hydraulic pump is open, transparent, and can be found on the Internet. However, there is still a big gap between the hydraulic pumps manufactured by Chinese companies and those imported from Germany.” Linde Hydraulics, Germany, two years ago Trained for a period of time, Wang Jian, who visited many companies in Germany, is now a quality engineer for Linde Hydraulics-China Weifang Plant. He admitted to the author that German equipment can be imported, but the control in the manufacturing process, the gap between China and Germany is still very clear. These gaps are reflected in materials, process innovations and workers' skills.

In 2012, Weichai Group reorganized the German KION Group and Linde Hydraulics. In order to break the pattern that China's high-end hydraulic components are completely dependent on imports and upgrade the level of domestic hydraulic components, on May 29, 2015, Linde Hydraulics-China Weifang Plant went into operation. After selection, Wang Jian and 8 other young people with higher academic qualifications and certain working experience became the first employees of Linde Hydraulic Weifang Plant.

The world's most advanced hydraulic parts manufacturing landing Weichai

In the Weichai Group's vast industrial park, the signage of Linde Hydraulics-China Weifang Plant is not conspicuous, but its production has a landmark meaning. This not only means that Weichai Hydraulics has taken a solid step, but also means that Weifang has a The ability to produce the world's most advanced hydraulic components.

According to Ulrich, the CEO of Linde Hydraulics, the new plant can effectively reduce production costs and shorten the time to market, and through the comprehensive cooperation of resources with Weichai, it greatly enhances the procurement, manufacturing, and service capabilities of Linde Hydraulics. Satisfy the needs of Chinese customers and lay a solid foundation for Linde Hydraulics to explore the Chinese market.

Sun Shaojun, CEO of Weichai Power, said that Weichai will rely on its existing rich resources to strengthen collaboration and help Linde Hydraulics become the world's best manufacturer of hydraulic powertrain systems.

In 2012, Weichai Power International restructured Linde Hydraulics and both teams proposed to position the hydraulic business as a strategic business of Weichai Holding Group. It was determined that Linde Hydraulics will be built as a full-series, all-area, global technology-leading, and ranked The strategic vision of the world's top two manufacturers of hydraulic powertrain systems, using hydraulic business as a platform to "recreate a Weichai power."

After repeated arguments, the two parties reached a consensus — to set up a joint venture company in Weifang and invest in the construction of a hydraulic factory to accelerate the localization of high-end hydraulic components, and to rewrite the history of China’s dependence on imports of high-end hydraulic components, allowing “European Quality + Chinese Cost”. The two-wheel drive model landed at Weichai.

In 2013, 8 employees from Weichai, including Wang Jian, began to study at Linde Hydraulics (Xiamen) Co., Ltd. in Xiamen. Later, they flew to Linde Hydraulics in Germany for training. In 2014, Linde Hydraulics China was established.

Zero distance feels made in Germany

As the most powerful automobile and equipment manufacturing group in China at present, Weichai’s pavilions and workshops in Weifang receive a large number of visitors every year. Nowadays, the Linde Hydraulics-China Weifang Plant, which represents the world's most advanced level, has become a new target for visitors to visit. In recent days, the author also experienced a "zero distance" experience from Germany.

To enter the new factory, you must first "hair blow." The factory gates are three sealed glass doors, each entering a glass door, and the back door must be closed immediately. After entering the first door, there is a waiting area. After entering the second door, multiple air outlets on the wall will blow guests from head to toe at the same time. Then they can open the third door and enter the workshop.

If the second door does not close when it blows, then it must be closed to reopen the third door to enter the workshop. This "hairdry" link became the first impression made by many visitors on German manufacturing.

"Hydraulic parts are precision parts. A little dust can affect the precision. A blow can blow off the dust on the guests," explained Wang Jian.

All the equipment of this new factory is imported from Germany. For example, in a new workshop, on an assembly line, several workers are systematically assembling hydraulic pumps. All the tools are neatly placed on the support plate.

The humble bracket board is very convenient to use, and it can be equipped with a number of different special tools according to needs. The position of the tool is clear at a glance, which minimizes the work intensity and improves work efficiency. Many companies emphasize the 5S management of the workshop, which is easily achieved here.

Wang Jian took up the main parts of the hydraulic pump plunger to explain their innovative concept. “This plunger has high precision and the design concept is very unique. The plungers of other brands are all shoes with plungers and copper-clad steel structure. Linde's plunger is wrapped in shoes and steel ladle steel structure, which can make the swash plate angle can be tilted the most, up to 21 degrees, while other brands can only reach 18 degrees, this design brings the advantage is In the case of the same displacement, the component size is smaller, the installation space is more economical, and more importantly, the reliability of the connection between the shoe and the plunger is improved, and the length of the plunger is increased, so that the low speed stability of the motor is obtained. Greatly improved."

The hydraulic pump factory test bench imported from Germany is another highlight of the new plant. "A lot of manufacturers want to come and see this test bench." Wang Jian said that the test bench is currently the most advanced fully automatic test bench in China.

Compared with test benches from many manufacturers, the test bench is more accurate and complete in terms of technical parameters, and it can provide 50Mpa test pressure. Therefore, the qualified hydraulic pump is more accurate, reliable and durable.

Representing the world's top quality requirements, Made in Germany, it is a manufacturing powerhouse – a benchmark that China is advancing toward manufacturing power.

In order to improve industrial competitiveness, China has launched “China Manufacturing 2025”, a strategy similar to German Industry 4.0, to reflect the integration of information technology and manufacturing technology into a digital, networked, and intelligent manufacturing industry to accelerate the transformation and upgrading of manufacturing industries and improve quality and efficiency. , Strive to make China from manufacturing to 2025 into the ranks of manufacturing power. In July, the Ministry of Industry and Information Technology announced the pilot demonstration project of intelligent manufacturing in 2015. Weichai Power successfully entered the list.

However, there is still a long way to go before the Chinese version of the Industry 4.0 strategy is put on business. In addition to industrial accumulation in China and Germany are not in a segment, under the pressure of economic downturn, how companies can balance the immediate crisis with the long-term development of the relationship, from the moment to the beginning of a practical step towards China to create 2025, requires vision and wisdom. In this context, the commencement of production of the Linde Hydraulics-China Weifang Plant means that Weichai's dream of catching up with the Germans is to open up in the process of keeping a low profile.
