Under normal circumstances, we divide auto parts into original parts and sub-factory parts, but in fact, the classification of parts is not so simple. The correct classification mainly includes original parts, genuine parts, sub-factory parts, disassembled parts and three None of these five categories.

　　First of all, automobile manufacturers, namely OEMs, master the key technologies of core components such as engines, gearboxes, and chassis. However, a car has thousands of parts, so it is impossible to build a single factory. It specializes in the production of those non-core parts, so some expensive core technical parts such as some lamps, plastic decoration parts, body panels, seats, door glass, etc. on the car are mostly outsourced. will not produce itself.

　　Original parts refer to the parts that the supplier produces according to the standards of the main engine factory, and after the production is completed, it is sent to the automobile manufacturer for inspection and then put into storage. The workmanship of regular original auto parts is perfect, basically the same quality as the original parts, no small flaws, the appearance and performance are consistent with the original parts, and there are professional qualification certificates, and the manufacturer's LOGO and part number will also be marked . Generally, most of the original parts are in 4S stores, which are specially provided by car manufacturers for after-sales supply, and its adaptability is the best.

　　Genuine factory parts, the difference between original factory parts and genuine factory parts is that for some reasons, the parts factory does not enter the procurement list of the main engine factory, so it cannot print the logo of the car manufacturer on the parts and packaging. The advantage of genuine parts is that they have a quality assurance that is close to the original parts, but the fit of some parts may not be as good as the original parts. For example, the tires of the original parts are more comfortable. , may pursue wear resistance, and its comfort is not as good as the original parts.

　　Sub-factory parts, sub-factory parts mainly come from relatively small manufacturers. Although it is not in the procurement list of automobile manufacturers, these manufacturers also have the corresponding production capacity. For example, your car lights are made by Valeo Production, and the profit of this lamp on the market is very considerable, some manufacturers will buy it back and dismantle it, open the mold again, and manufacture and sell it.

　　The price of sub-factory parts is cheaper than original parts, but it is subject to technical costs. The quality of sub-factory parts is uneven. If you want to replace some key components such as the power system, brake system, and steering system, it is recommended to use original parts for insurance purposes.

　　And if there are some accessories that basically have no effect on the driving safety of the vehicle, such as air conditioner filters and headlight covers, we can still use sub-factory parts. In addition, the order cycle for original parts is relatively long, and the supply of sub-factory parts is relatively large, which is also a major advantage of it.

　　There are two types of car dismantling parts. One is pure dismantling, which mainly refers to almost brand-new accessories. For example, a car owner buys a new car and wants to upgrade the halogen headlights on the car to LED lights. The removed halogen headlights can be regarded as pure disassembly. In addition, there is another kind of disassembled parts, which are generally parts from scrapped cars in accidents and scrapped car factories. Since these parts have been used for many years, the quality is naturally not as good as that of pure disassembled parts, and there is no quality guarantee.

　　High imitation hardest hit areas, three no pieces. The auto parts used in cars need to pass the national 3C certification, and some small workshops, even this counterfeit manufacturer, naturally cannot pass the national 3C certification, including many refurbished parts, which will scrap the parts of the accident car Reprocessing and refurbishment, and then entering the market, many car owners are greedy for cheap and choose Sanwu. In addition, online shopping is also a hard-hit area where Sanwu is infested. Cars are related to driving safety. For the sake of safety, please boycott Sanwu. .
