What is a good way to buy auto parts products? How can I buy the most suitable and cost-effective auto parts? Here, I recommend the following tips to help you choose the best auto parts: The loss should be returned.
1. Look at the packaging. The packaging of original accessories is generally standardized, unified standard specifications, and the printing is clear and regular, while the packaging and printing of counterfeit products is relatively poor, and it is often easy to find flaws in the packaging;
2. Look at the color. Some original parts specify a certain color on the surface. If they encounter other colors, they are fake and inferior parts;
3. Look at the appearance of the original parts. The printing or casting and marking of the original parts are clear and regular, while the fake products are rough in appearance;
4. Look at the paint. Unscrupulous merchants simply process the waste parts, such as dismantling, assembling, assembling, assembling, painting, etc., and then sell them as qualified products to illegally obtain high profits;
5. Look at the texture. The original parts are made of qualified materials according to the design requirements, and the counterfeit products are mostly replaced by cheap and inferior materials;
6. Look at the process. Although the appearance of inferior products is sometimes good, because of the poor production process, cracks, sand holes, slag inclusions, burrs or bruises are easy to appear;
7. Look at "storage". If there are problems such as dry cracking, oxidation, discoloration mirror or aging of auto parts, it may be caused by poor environment, long storage time, and poor materials during storage;
8. Look at "joining". If the clutch plate rivets are loose, the brake hoses are degummed, the joints of electrical parts are disconnected, and the paper filter element is disconnected, it cannot be used;
9. Look at the logo. Some regular parts are marked with certain marks, such as the hour gear mark, the piston top mark and other assembly marks to ensure the correct installation of the machine parts.
10. Look at the omissions. The regular assembly parts must be complete and intact to ensure smooth loading and normal operation. Some individual small parts on the assembly parts are missing, generally "parallel imports", which cause difficulties in loading. Often due to the shortage of individual small parts, the entire assembly component is scrapped;
11. Look at the protective layer In order to facilitate storage and prevent the parts from bumping, the parts have a protective layer before they leave the factory. For example, bushings, large and small bearings, pistons, valves, etc. are generally protected with paraffin wax to prevent surface damage. These important accessories, if there is no protective layer on the surface, are mostly "parallel imports";
12. Look at some important parts of the certificate, especially the assembly category, such as carburetor, distributor, generator, etc., when they leave the factory, they usually have manuals and certificates to guide users in installation, use and maintenance. Counterfeit and shoddy products;
13. Look at the specifications. When purchasing auto parts, you must find out the main technical parameters, and the special technology must meet the requirements for use. The appearance of some counterfeit and inferior products is almost the same as the real one, but it is not suitable to be installed. It is either larger or smaller. It is always unsatisfactory to use and leaves hidden dangers of accidents.
14. The test report issued by a third party can not only prove the authenticity, but also show the quality of it.
