Do everything possible to meet the needs of users

Axle is the key part of semi-trailer, which occupies an important position in the spare parts market. In recent years, careful car owners have noticed an increasing number of axle axle covers with the word "DR", and this "DR" is the DARO trailer axle logo.

DARO axle, can be said to be one of the leaders of Liangshan axle enterprises, has accumulated a history of more than 20 years. In the past 20 years, Liangshan's axle enterprises have developed from a few to more than 200, but Darong has always been able to remain invincible.

Today, we asked Liang Sheng Ren, workshop director of DARO Group, to share with us the key to DARO's success.

Adhere to good quality to build a solid foundation for enterprise development

At the beginning of its establishment, DARO Group's main business was axle semi-finished products. In 2003, the company developed "one-piece" axle production equipment through independent innovation, becoming the first enterprise in Liangshan to achieve "one-piece" axle mass production. Up to now, DARO Group has successfully extended its products to all kinds of finished axles and provided more and more diversified services to users.

Director Ren believes that whether the axle is semi-finished or finished, DARO trailer axle can get the trust of users, in addition to continuous innovation, the more important thing is that the quality is always reliable.

"For manufacturing companies, product quality is life." Ren said, "Especially the axle, related to the bearing, braking and driving of the vehicle, if the quality is not qualified will directly affect the driving safety. So it is our duty to ensure the quality of our products."

According to the introduction, the quality control of DARO mainly involves four aspects: raw materials, production process, parts and quality inspection:

In terms of raw materials, the DARO trailer axle chooses 20Mn2 high-strength alloy seamless steel pipe. The wall thickness of conventional models is about 10-11mm, and the wall thickness of special type axle is higher. "20Mn2 steel has good comprehensive mechanical properties, such as tensile strength, yield strength, impact toughness, machinability, weldability and other indicators are better than general steel." Director of the introduction said.

After ensuring the quality of raw materials, quality control of the production process is followed. DARO Group has a total of 15 processes, covering hot rolling, cold push square, automatic quenching and tempering, shot blasting, multi-point straightening, CNC machine tool processing, medium frequency strengthening treatment, primer + top paint spraying, machine welding protection, finished product assembly, from internal mechanical properties to external processing accuracy, fully in line with national standards.

DARO axle is selected to purchase parts, such as brake drum, hub, bearings, etc. are supplied by domestic strength manufacturers. On the one hand, these brands in the accessories industry for many years, quality through the baptism and test of the market, with the corresponding quality assurance ability; On the other hand, after the arrival of the parts, DARO also needs to conduct a series of quality inspection procedures, and only after the parts are qualified can they be put into use, which is equivalent to an extra layer of quality assurance.

In the process of quality inspection, DARO Group has established a complete quality supervision system, which implements unified and strict quality control from raw materials to design, manufacturing, testing and sales. At the same time, it has set up quality inspection workshops such as fatigue test, salt spray test and magnetic particle flaw detection test of axle body, equipped with high-precision instruments to accurately test the stress limit of axle. To ensure that no fatigue failure occurs during the service period.

Under such strict quality control, DARO axle successfully passed the ISO quality management system certification, and created a legendary monthly sales record of 7,000, and successfully went abroad, into the world famous brands.

Rich product lines to meet the differentiated needs of users

After years of development, DARO Group's product line is more diversified, including American style and German style two categories. In the DARO exhibition hall, Director Ren introduced a 13t American axle: "This axle is the one with the highest order quantity of Darong at present, and is also the one with high application rate in China. We can often see it on the road. This axle cost performance is very high, parts for the industry's general model, simple design, maintenance and replacement is more convenient, in addition to the continuation of the American axle anti heavy load characteristics, tonnage from 10t-25t, can adapt to most of the transport conditions."

With the advent of Class C6 driver's licenses, passenger cars can pull trailers on the road, and a variety of light trailers have begun to emerge, such as trailer trailers. Compared with traditional semi-axle, axle tonnage required by these models is often smaller, wheel pitch and other parameters are more niche, lack of unified production standards, so it is difficult to find perfect matching products in the market.

"In fact, not only these new models, some trailers in special areas, such as farm trailers, or flat trailers used in transfer stations, stations and warehouses, due to different functions, it is also very difficult to match the axle." "In response to this phenomenon, DARO has specially developed customized services, based on user-provided parameters or drawings, to carry out targeted design and production. If customers aren't sure how to match the parts, we also offer a complete axle solution, designed to give customers the perfect axle match for their vehicle."

Since the launch of DARO customized axles, it has been widely welcomed by domestic and foreign markets, especially from Inner Mongolia, Xinjiang, Northeast China, Australia, Europe and other countries, the order volume soared.

In the face of rising orders, Ren said that DARO factory has made sufficient preparations to ensure that the production task can be completed on time, with good quality and quantity, and the products can be delivered to users as soon as possible.

Think what customers want, meet what customers are anxious about, and meet what customers need. Since entering the market for more than 20 years, DARO has always adhered to the cost-effective route. It disdans to seek benefits with low quality, nor does it rely on quality to sit on the price, focusing on creating real, affordable and practical products. With many trailer factory, logistics company, transport fleet and retail to establish a good and stable relationship of cooperation.
