In China's commercial vehicle production and manufacturing territory, there are mainly four commercial vehicle bases in Suizhou, Hubei, Longyan, Fujian, Liangshan, Shandong and Tieling, Liaoning. They stand in full swing and have the same momentum. They can be called the leader of the industry. Darong heavy industry group is the representative of Shandong Liangshan axle enterprises.

In 2001, Darong heavy industry group was established in Liangshan, then known as Darong Transportation Machinery Co., Ltd., which is the first axle enterprise in quanpu Industrial Park. Now, 20 years later, there are more than 200 local axle factories, large and small, but foreign merchants still like to go straight to Darong group when they arrive in Liangshan, and Darong axle is still the first favored object of users.

So, what is the originality of this axle enterprise? Today, let's decode the enduring secret of Darong in the changeable market.

Independent innovation helps enterprises take off

Darong heavy industry group is located in Guoyuan Road, quanpu Town, covering a total area of about 60000 m2, including a plant area of about 32000 m2. Such scale and standard are also second to none in Liangshan. It is understood that since the establishment of Darong, the workshop production line has been upgraded and innovated for six times. At present, it adopts the domestic advanced intelligent production line, which realizes automation from manufacturing to assembly and product testing, with a total investment of nearly 1.5 billion yuan.

If you want to produce first-class products, the hardware conditions should meet the standards, and all kinds of soft power should keep up. If you want to gain a firm foothold in the market, you must keep up with the pace of the times, which requires enterprises to have a certain ability of independent innovation. Around the line of "independent innovation" and "self-reliance", Darong group has made a lot of efforts in product design, product R & D and production technology.

Director Du of the R & D department said that Darong group faced many technical difficulties at the beginning of its establishment. At that time, the axles produced in China were still three joint type. Some leading enterprises produced integrated axle tubes with the help of foreign technicians, but they built high technical barriers to occupy the market. At that time, Darong group did not have a special R & D department. The chairman personally led the workshop technicians to carry out the research on the production process of integrated axle without any guidance, reference and reference technology. After nearly two years of efforts, it tested nearly 200 tons of waste and finally solved this problem, It also fully considers the use needs of domestic users and optimizes and improves the design.

Today, Darong's R & D team has reached 30 people, including doctors, masters, returnees, and many members with senior professional titles who have been engaged in axle and axle design and R & D for many years, with rich relevant experience.

Director Du said that the axle is an important part of the trailer chassis and plays a vital role in the driving, load-bearing, braking and other safety performance of the trailer. Therefore, the design and R & D of the axle need to be more rigorous and careful, not careless at all. Once defects are found in the experiment, it is common to work overtime. "In 17 years, we designed a new product, but we found that there was some deviation from the estimated value during the experiment. It took us nearly a month to design that product. When we saw that, everyone was unhappy and didn't eat or sleep well. We stayed up all night for several nights and finally found the problem and solved it successfully At this moment, we feel very secure. "

Darong people know that it is not proud to be ahead of others. It is their ability to be ahead of themselves. Inspired by this spirit, Darong group has continuously cultivated on the road of continuous independent innovation, and successively developed and manufactured a series of products such as disc axle, German axle, American axle, concave axle, special axle and three-line six axle axle axle to meet the needs of users and realize its own development and take-off.

Strict standards create reliable quality

Under the leadership of the workshop director, we visited the production workshop of Darong group.

Director Ren introduced that although the number of axle enterprises is increasing, the real production-oriented enterprises still account for a small number. On the one hand, it is expensive to build a set of fine and standardized plants. Moreover, now the axle industry has entered a period of rapid development. If it does not have core advantages, it is easy to be left behind by the industry. Some manufacturers dare not take risks in this regard, so they choose to take the semi-finished products produced by large factories back, assemble them into finished products, and then sell them to the market. In this way, although you can get a share in the axle industry, you can't make your own brand by relying on others.

Director Ren also made a detailed introduction to us on various production links. From the initial blanking, a qualified Darong axle has to go through 15 processes before and after production, including raw material cutting, hot rotary rolling, shaft head processing, high-precision shaft tube forming, full-automatic medium frequency quenching, integrated shaft tube heat treatment, sand blasting and rust removal, on-line alignment, CNC precision grinding, medium frequency induction treatment, secondary finishing, comprehensive shaft tube inspection Automatic gas shielded welding, painting + electrophoresis, finished product assembly. If it is a special size axle, it needs to add two more precision grinding, so that the products can fully meet the standards in terms of stiffness, toughness, wear resistance, fatigue resistance and other comprehensive mechanical properties.

Each Darong axle has to go through such a cumbersome and precise production process.

Not only that, after the finished product assembly is completed, it also needs to pass the online + offline dual quality inspection. Only after passing the limit performance test of the test workshop can it enter the market smoothly.

Director Ren said that at present, Darong group is preparing to launch a batch of new quality testing instruments, with an investment of about 25 million, which can be installed only after the instruments are produced. With these new quality inspection instruments, the online detection efficiency of products will be greatly improved. Moreover, the new quality inspection instruments will be fully integrated into the existing production line. After each processing process, they will undergo online quality inspection. Only when they fully meet the standards can they be entered into the system and enter the next production process. In this way, there will be no escape for quality problems, Fully prevent unqualified products from entering the market.

Real price shows strong strength

Corresponding to the practice of adhering to reliable quality and never retreating, Darong group also has its own adherence to product prices.

In the current axle Market, the polarization is more serious. On the one hand, the quality is reliable but the price is super expensive, on the other hand, the price is cheap but the quality is worrying. Darong axle is a special case. Different from other brands, Darong group never starts the price or adds water to the price depending on its axle quality. Since entering the market for 20 years, Darong has always insisted on giving back to users at the most reasonable price.

In the words of chairman Zhang, Darong group has gone through a lot of ups and downs from its initial establishment to now. If it were not for the trust and support of friends from all parties, Darong might not have developed to today. As the saying goes, "be honest and do things honestly". No matter how the industry develops and how the market changes, Darong group should adhere to integrity and gratitude, do not adulterate the price, and build a cost-effective axle to make customers more affordable.

      "Building a world-class commercial vehicle axle brand and being a adherent and innovator in China's machinery manufacturing industry" is the corporate mission of Darong group and the constant course of Darong group in the past, present and future. Today, Darong axle sales network has spread all over the country and is exported to more than 50 countries and regions such as Europe, America, the Middle East and Southeast Asia. In the future, we believe that with the international front-line quality, fair price, unremitting innovation and sincere attitude and service, Darong will eventually become the backbone of quality in a big country and the leading brand in the axle industry at home and abroad.
