Product quality is the basis for the survival of enterprises, especially for axle enterprises. Only if the quality of the axle meets the standard can it provide customers with safe and reliable use guarantee and win wide recognition in the market.

In Darong Group, the first principle of corporate values is quality first. After entering the market for more than 20 years, Darong has always adhered to the strict and persistent attitude of quality control, put quality testing in front of the raw material link, and built a complete quality control system, and established more strict technical standards and quality management system on the basis of industry standards.

1、

Rigorous+normative

Eliminate possible quality problems in the production process

To ensure product quality, the production process is the most important. At the Darong axle, each axle has to go through more than ten processing processes, including thermal conditioning, shot blasting, multi-point straightening, axle head finishing, medium frequency induction strengthening, primer+finish paint, machine manual welding, automatic assembly, etc. The production accuracy is in strict accordance with the JTT475-2020 trailer axle product implementation standard.

At the same time, Darong has established strict regulations on process inspection, and the operation of all posts must strictly follow the operation instructions to avoid quality defects caused by non-standard operation. From incoming material inspection, in-process inspection, semi-finished product inspection, to finished product inspection, warehousing inspection, and delivery inspection, only when all of them pass the inspection and meet the acceptance standards can they be successfully delivered and put into use.

2、

Precision+professional

Provide strong guarantee for quality inspection

Quality inspection is the supervision of production quality, and it is also a test of testing instruments. If you want to verify the details of axle quality, you need to equip high-precision, authoritative and reliable instruments.

To this end, Darong Axle has specially set up an experienced quality inspection team, invested in automatic and intelligent testing equipment such as spectrum detector, metallographic microscope, universal tensile testing machine, fatigue testing bench, impact testing machine, Rockwell hardness tester, magnetic particle flaw detector, salt spray testing machine, and formed a complete performance testing and evaluation mechanism for raw materials, semi-finished products, and finished products;

At the same time, Darong strives to improve the number of professional quality inspection personnel, enhance and improve its own inspection level, provide a strong guarantee for accurate and efficient inspection of product quality, and fully ensure that every ex-factory product is qualified through rigorous inspection.

There is a saying in the industry that the head of Shaanxi, the head of Shandong, and the axle of Liangshan run the world. As one of the earliest axle enterprises in Liangshan, Darong Group has been focusing on the R&D and manufacturing of high-quality axles. Darong firmly believes that one more inspection process is equal to one more layer of security, which can make customers more safe and less trouble in subsequent use. In the future, Darong will continue to work hard in the field of semi-trailer accessories to provide customers with affordable, practical and practical products and services.
