Trailer is one of the transportation tools often used in transportation industry. With the continuous development of domestic logistics and transportation industry, the sales volume of trailers has also increased by leaps and bounds. Correspondingly, the market demand for trailer accessories is also rising. Trailer axle is one of the typical representatives.

The rising market demand has attracted more people to enter the axle industry and try to get a share of it. Large and small axle factories have sprung up. The number of axle factories has exceeded 200 in Liangshan commercial vehicle production base alone. Open the Internet, a search, a variety of brands is dizzying.

Although there are a large number of axle manufacturers, few of them really do well. Why do you say that?

Although it seems that the shape of the trailer axle is relatively simple, in fact, its structure is relatively complex, there are a large number of parts, and the requirements for the accuracy of the production and assembly process are also quite high. As the axle bears the load-bearing, braking and driving maintenance functions of the trailer, its seemingly simple shape is also developed through rigorous design. Even if it changes one millimeter, it has to undergo countless experiments to avoid affecting the performance of the finished product.

In terms of production and manufacturing, the trailer axle must go through a series of processes such as heat treatment, quenching, tempering, sand blasting, straightening, grinding and painting. The more advanced the process is, the more stable the comprehensive mechanical properties of the axle will be. Especially now, the industry generally pursues the trend of lightweight, and wants to realize the weight reduction of the axle without affecting the rigidity and toughness of the product, which is quite a test of technology and strength. Then there is the choice of raw materials. The higher the quality of raw materials, the more it can provide a higher standard basis and guarantee for subsequent production and use. In order to ensure the quality of finished products, quality inspection and performance test are essential.

What if the technology, strength and experience fail to meet the standards? There is another way: processing semi-finished products. Buy semi-finished axle products from large factories and assemble them into finished products for sale. At present, many small manufacturers choose this processing method. I'm afraid it remains to be discussed whether the quality of selected parts and components and assembly technology and conditions meet the standards.

Therefore, to buy a trailer axle, you also need to identify brand products. So, what Trailer brands do well in Shandong Province?
