Literacy of auto parts classification, original parts, original parts, auxiliary parts, disassembled parts, and three no parts

Generally, we divide auto parts into original parts and auxiliary parts, but in fact, the classification of parts is not so simple. The correct classification mainly includes original parts, original parts, auxiliary parts, disassembled parts and "three no's" parts.
First of all, automobile manufacturers, namely OEMs, have mastered the key technologies of some core components, such as engines, transmissions and chassis. However, a car has thousands of parts. It is impossible to say that a separate factory is being built to manufacture non core parts. Therefore, some lamps, plastic decorative parts, body covering parts, seats, door glass and other core technical components are required, Most of them are outsourced, and the OEMs will not produce by themselves.
The original parts refer to the parts that are produced by the supplier according to the standards of the main engine manufacturer and then sent to the automobile manufacturer for inspection and warehousing after production. The standard original auto parts are of perfect workmanship. They are basically the same quality as the original parts. They have no minor defects, and their appearance and performance are consistent with the original parts. They also have professional qualification certificates, and they are also marked with the manufacturer's logo and part number. Generally, most of the original parts are sold in 4S stores. They are specially provided by automobile manufacturers for after-sales service. Their adaptability is the best.
The main difference between genuine parts and genuine parts is that the parts factory has not been included in the purchase list of the OEM for some reasons, so it cannot print the logo of the automobile manufacturer on the parts and packaging. The advantage of genuine parts is that they have the same quality assurance as the original parts, but the adaptability of some parts may not be as good as that of the original parts. For example, the tires of the original parts are more comfortable. The genuine products of the same specification may be more wear-resistant, and their comfort is not as good as that of the original parts.
Auxiliary factory parts, auxiliary factory parts are mainly from relatively small manufacturers. Although they are not in the purchase list of automobile manufacturers, these manufacturers also have the corresponding production capacity. For example, your automobile lamps are produced by Valeo, and the profits of this lamp on the market are considerable. Some manufacturers will buy it back, dismantle it, re mold it, and manufacture and sell it.
The price of the auxiliary parts is cheaper than that of the original parts, but it is subject to the technical cost. The quality of auxiliary factory parts is uneven. If some key components such as the power system, brake system and steering system are replaced, it is recommended to use the original factory parts to be safe.
However, if there are some accessories, such as air conditioning filter and headlight cover, that have little impact on vehicle driving safety, we can still use the auxiliary parts. In addition, the ordering cycle of original parts is relatively long, while the supply of auxiliary parts is relatively large, which is also its major advantage.
There are two kinds of disassembled parts. One is a pure disassembled part, which mainly refers to almost new parts. For example, an owner who bought a new car wants to upgrade the halogen headlamp on the car to an LED lamp. The disassembled halogen headlamp can be regarded as a pure disassembled part. In addition, there is a kind of disassembled parts, which are generally parts from accident scrapped cars and scrapped car factories. Since these parts have been used for many years, they are naturally inferior to the purely disassembled parts in terms of quality, and there is no quality guarantee.
High imitation of severe disaster area, three no pieces. All auto parts used in automobiles need to pass the national 3C certification, and some small workshops, even this counterfeiter, naturally cannot pass the national 3C certification, including many refurbished parts. The parts of scrapped accident vehicles are reprocessed and refurbished, and then put into the market. Many car owners are greedy for cheap, and choose "three no parts". In addition, online shopping is also a disaster area where "three no parts" come and go, and cars are related to driving safety, For the sake of safety, please boycott the "three no items".
