How do I know the names of auto parts?

1, the packaging of original packaging parts is generally standardized, the standard specifications are unified, and the printing is clear and formal, while the packaging and printing of counterfeit products are poor, and it is often easy to find defects from the packaging;

2. Look at the color. Some original accessories have certain colors on their surfaces. If you encounter other colors, it is fake and shoddy parts;

3. look at the appearance. The printing or lettering and signs of the original parts are clear and formal, while the counterfeit products are rough in appearance;

4, see paint unscrupulous businessmen will waste parts after simple processing, such as disassembly, assembly, assembly, painting, etc. , and then pretend to be qualified products for sale, illegally obtaining high profits;

5. See that the materials of the original accessories are all qualified materials according to the design requirements, and counterfeit products are mostly replaced by cheap and inferior materials;

6. Although the appearance of products with inferior technology is sometimes good, cracks, sand holes, slag inclusions, burrs or bulges are easy to appear due to poor manufacturing technology;

7. Look at the "storage" of auto parts. If there are problems such as cracking, oxidation, discoloring mirror or aging, it may be caused by poor environment, long storage time and poor materials.

8. Look at "joints". The clutch plate rivet is loose, the brake hose is degummed, the joint of electrical parts is off-welded, and the joint of paper filter element falls off, so it cannot be used;

9. Look at this sign. Some regular parts have certain marks, such as assembly marks such as time gear marks and piston top marks, to ensure the correct installation of parts, and those without them cannot be purchased;

10. See if there are any defects. Conventional assembly parts must be intact to ensure stable posture and normal operation. Some small parts on the assembly are missing, which are generally "parallel imports" and are difficult to load. Often due to the shortage of individual small accessories, the whole assembly parts are scrapped;

1 1. Look at the protective layer. In order to facilitate storage and prevent parts from bumping, parts are protected before leaving the factory. Such as bushings, large and small bearing shells, pistons, valves, etc. It is usually protected with paraffin wax to avoid surface damage. If there is no protective layer on the surface of these important accessories, most of them are "parallel imports";

12. Look at some important parts of the certificate, especially the assembly type, such as carburetor, distributor, generator, etc. Instructions and certificates are generally attached when leaving the factory to guide users in installation, use and maintenance. Without these, most of them are fake and shoddy products;

13. Look at the specifications. When buying auto parts, you should know the main technical parameters, and the special technology should meet the use requirements. Some fake and shoddy products look almost the same as the real ones, but they are not suitable for installation, or they are bigger or smaller, and they are always unsatisfactory to use, leaving hidden dangers of accidents.
