The axle is one of the key components of the trailer chassis, bearing the role of supporting the body load, assisting braking, maintaining running, and cushioning the road vibration to a certain extent. From the perspective of composition structure, the axle is mainly composed of shaft beam and brake, wheel end, camshaft unit of various components.
Semi Trailer supplier says When buying an axle, the owner will frequently find such a problem: some parts of the axle factory are produced by themselves, and some are purchased from external suppliers. Which of these two ways of producing axle is better?
First of all, let's take a look at the advantages and disadvantages of homemade accessories and purchased accessories.
1, car and bridge factory homemade accessories
Advantages:
(1) For vehicle and bridge factories, an obvious advantage brought by homemade parts is that it can enhance the control of production costs, reduce the production cost of vehicle and bridge, and to a certain extent, it can obtain greater profit space.
(2) The auto and bridge factory can improve the control of the production process, production efficiency and production time, so as to better cooperate with the production planning of the auto and bridge and ensure the timely supply of parts.
(3) Self-produced parts form a closed loop, which can further enhance the coordination between finished products and parts. If any parts have problems or coordination is not excellent enough, the vehicle and bridge factory can directly discuss the internal solution.
(4) Self-made accessories can make full use of the car and bridge factory's own equipment, personnel, plants and other resources.
Disadvantages:
(1) Numerous kinds of parts required on the axle, such as hub, brake drum, brake pad, bearing, etc., its production standards and production technology are not the same, widely dabbled is not easy to specialize.
(2) Production standards and product quality are all self-controlled, whether to reach the unified standard of the market is not easy to define, but also depends on the specific strength of the manufacturer. According to the user's reflection, there have been some cases on the market where the quality of parts produced by individual auto and bridge factories is not up to standard, leading to the failure of the axle, which has to be paid attention to.
(3) Auto and bridge factory self-produced parts should also consider the problem of production saturation. If the strength, experience, scale and other absolute advantages, you can take out technology and energy into the research and development of parts production to go to the poor, I am afraid it is difficult to take into account the dual fields of axle and parts.
2. Outsourced parts from auto and bridge factories
Advantages:
(1) The supply chain of axle parts in the market is mature and perfect. There are numerous excellent and strong parts suppliers, and they have the corresponding ability to expand the supply varieties.
(2) Different from self-produced parts, parts produced by professional parts factories are usually supplied to different vehicle and bridge factories, which need to face a broader vehicle and bridge market. In other words, they need to accept additional frequency and opportunities for market inspection. Some well-known brands, after years of market baptism and verification, quality and performance are relatively more reliable.
(3) Professional R & D and production of spare parts, technology, experience, manpower and material resources can be completely invested, enterprises can not compete with their own spare parts.
(4) For vehicle and bridge factories, it is more convenient and faster to purchase spare parts, which do not need to disperse manpower and material resources, etc., and can focus on the continuous improvement and upgrading of core technologies.
Disadvantages:
(1) Accessories need to be purchased, the production cost increases accordingly, and the better the quality of the selected accessories, the higher the cost.
(2) The production schedule and delivery efficiency of spare parts are not under our control. If we cannot communicate properly with the spare parts factory in advance, it is easy to fail to supply the goods and affect the axle production.
(3) If there is a problem in the coordination between parts and axle, we can only communicate with the parts factory to solve it, which is not as efficient as internal negotiation.
It can be seen that the car and bridge factory homemade parts and purchased parts, both have advantages and disadvantages. Of course, the above is mainly analyzed from the perspective of vehicle and bridge factory.
If from the point of view of consumers, the main advantage of the vehicle and bridge factory to producing its own parts is the price. The production cost is reduced, and the price of the finished product of the vehicle and bridge will be reduced correspondingly, which is also a gimmick for numerous manufacturers to attract consumers.
Worth the attention of consumers is the need to do a decent job of quality screening. From the establishment of the manufacturer time, strength, scale, user reputation and additional aspects to understand. In addition, self-made parts ≠ low price, some top-end axle brands will not lower the price because of their own production of parts. On the contrary, they will be considerably higher. In addition to the factor of brand premium, the main factor is quality and performance.
In contrast, the car and bridge factory purchased parts, and the price may not be advantageous. Of course, those who choose three tiny workshop accessories do not count.
Although the price is a bit higher, the quality can be guaranteed. This point has been detailed in the article. Especially the head brand of the axle parts industry, its product quality stability and reliability is nearly recognized in the industry, and even numerous consumers directly specify their accessories when buying the axle.
In addition, after the arrival of the parts purchased by the axle factory, they are not directly installed and used, but need to go through a series of quality inspection procedures and be used after passing the requirements. This is equivalent to additional quality assurance and adequately ensures the stability and efficiency of the axle in use.
