The axle is one of the essential parts of semi-trailer. With the continuous improvement of the development level of the logistics and transportation industry, the axle products and technologies in the market are constantly updated and iterated. In the face of the increasingly fierce competition in the axle industry, it is undoubtedly the pursuit of most enterprises to create an independent innovative enterprise, establish product technology advantages, and adhere to the principle of self-reliance and self-improvement in science and technology.

This is also the development path that Darong heavy industry group has always adhered to since its establishment 20 years ago.

"Our goal is to create high-quality axles and axles, establish a world-class commercial vehicle axle brand, and be the adherent and innovator of China's machinery manufacturing industry."—— Du Cunxin, design director of R & D Department of Darong group.

Build brand strength steadily

Darong heavy industry group, founded in 2001, is a global axle / axle R & D manufacturer integrating "R & D, design, production, sales and service". It has its own brands "Daro" and "RSCC". Its products cover two major series of American and German models, including drum axle, disc axle, low flat axle, eccentric axle, concave axle, three-line six axle axle axle, special axle and axle semi-finished products.

In the interview, director Du mentioned many times, "we are a factory, and the products are the soul of the factory. We will try our best to do a good job in the products, make a higher cost-effective performance, and let users obtain a higher product value. This is the direction we will go." This is the original intention of Darong and the creed that Darong adheres to all the way.

After more than 20 years of precipitation and accumulation, Darong has established a sound R & D system, established an independent R & D department, equipped with a number of senior professional titles, doctoral and various technical talents, specializing in machinery manufacturing and mechanical mechanics, with an average age of 35 years. It is an experienced, high-quality and high-level R & D team. The company has successively passed the certification of three management systems of quality, environment and occupational health. At the same time, it has organized 43 research and development projects, completed 25 scientific and technological achievements such as new products, new technologies and new equipment, and has 14 national invention patents including utility models, which has been highly recognized by the industry.

Darong's achievements today are not achieved overnight. According to the introduction of director Du, in 2004, Darong started the research and development of "integrated axle tube" production equipment. At that time, the axle industry was seriously polarized, and the core technology was concentrated in the hands of foreign capital and leading enterprises. It was impossible to obtain relevant guidance or reference. At that time, Darong did not have a special R & D center, only a few technical personnel. They gathered together to ponder and discuss day and night, and changed the drawings bit by bit. Then they tried again and again according to the drawings. If they were wrong, they changed and tried again and again. Finally, after consuming more than 100 tons of test waste, they developed the mass production equipment of "integrated shaft pipe".

Although compared with the international first-line brands, Darong's "integrated axle tube" mass production machine started late, the axle tube produced by it not only rivaled foreign-funded products in quality, but also was closer to the use needs of domestic users. Once it was launched, it received the attention of the market. Some customers even went to Liangshan one month in advance to order to grab the Darong bridge. The Darong people's spirit of facing difficulties, not being impatient, and being down-to-earth has taken root and continued.

R & D innovation to expand the field of new products

Under the influence of the epidemic, many industries are facing great impact, including the axle industry. Kedarong has been actively responding to the epidemic, and has always maintained the due progress of research and development in the past few years.

"In the current environment, it is vital for the development of enterprises to expand new product areas and open up new growth space. In short, we will do what the market lacks and needs." Director Du said. Market driven reverse R & D, capture market demand, and develop personalized products in combination with the application characteristics of the axle.

In recent years, the number of customers who contact Darong group to consult the trailer bridge has been increasing, such as flatbed trailers, agricultural trailers, industrial trailers, caravans and so on. Different from semi-trailer, the application fields and specific functions of these vehicles are often different, so there are also various differences in the requirements for the axle.

"In the current commercial vehicle axle Market, the standard axle is still the main one, such as semi-trailer axle. The tonnage or track width are relatively concentrated, which is easy for manufacturers to produce and convenient for users to buy." Director Du said, "in contrast, trailers are different. The application fields of trailers are more extensive. There are many functions in the same application field, such as agricultural trailers, harvesters, grain, grass and fertilizer. The functions are varied. Their tonnage and track width are generally different. The axles that can meet the use can only be customized."

The drawing is the key to customize the axle. It is the guide and specification for the production and processing of the axle. Its accuracy directly affects the processing accuracy of subsequent production processes. After the user's requirements are submitted, Darong R & D center shall first hold a meeting to discuss and analyze, determine the product structure, specification parameters, parts collocation, process data, material properties, processing accuracy requirements, etc., design the corresponding product drawings, and on this basis, improve the processing drawings and the machine and equipment commissioning scheme of each production and quality inspection process, so as to lay a good foundation for the implementation of subsequent production and processing. The production technology and experience accumulated by Darong group over the years have provided a feasible guarantee for the processing of customized axles.

"Our goal of introducing customized trailer axles is to enable every customer of Darong to use axles that can perfectly match their own models. In addition to customized production, we have also launched a full range of axle solutions, mainly for customers who have not been in this field before. For example, if you don't know how to match the accessories, you can choose directly from our solutions, which can save more worry and effort."

After Darong's customized trailer bridge entered the market, it helped many Trailer users solve the problem of difficult to buy the bridge. More and more customers are looking for Darong's "private customization", most of them are from Inner Mongolia, Xinjiang, Northeast China, Russia, Australia, Europe and Southeast Asia. The demand is mainly for small tonnage, lengthened, high load-bearing, High-equipped and other special-purpose vehicle bridges. It is not uncommon to buy back many times.

Looking at the development of the market, changes are the normal. Only by constantly innovating and improving the ability of independent research and development can we remain invincible. Darong group takes innovation as its core value, aiming to continuously provide new technologies, new processes and new products for the market through independent innovation and create better products and services for customers. "In fact, the essence of innovation is to do a good job in every product, which is also the original intention of Darong."
