Auto parts identification method

1. Look at the appearance of the original parts of the original parts of the printing or casting and the mark is clear and regular, and the appearance of counterfeit products is rough.

2, look at the color Some original parts of the surface specify a certain color, if other colors, it is fake and shoddy parts.

3, look at the quality of the original parts of the materials are used according to the design requirements for qualified materials, counterfeit products are mostly used in modest and inferior materials.

4, look at the paint unscrupulous merchants will be through the simple processing of waste parts, such as dismantling, loading, spelling, scraping, painting, etc., and then pretend to sell qualified products, illegally obtain high profits.

5, see 'joining' If the clutch plate rivet loose, brake tube degumming, electrical parts joints off welding, paper filter joints disconnected, etc., can not be used.

6, look at the logo on the regular parts marked with some marks, such as the gear mark, the top mark of the piston and other assembly marks, to ensure that the machine is properly installed, no one can not buy.

7, look at the 'storage' auto parts if there are problems such as chapped, oxidized, discolored mirror or aging, may be caused by poor environment, long storage time, poor materials and other reasons.

8, look at the packaging of the original factory packaging is generally more standardized, unified standard specifications, printed and written clearly and regular, and counterfeit products packaging and printing is relatively crude, often can easily find flaws from the packaging.

9. Look at some important parts of the certificate, especially the assembly categories, such as carburetor, distributor, generator, etc., usually with instructions and certificate to guide the user to install, use and maintain, if not, Fake and shoddy products.

10. Look at the protective layer. In order to facilitate the storage and prevent the parts from colliding, the parts have a protective layer before leaving the factory. For example, bushings, bushes, pistons, valves, etc. are generally protected with paraffin to avoid surface damage. These important accessories, if there is no protective layer on the surface, are mostly 'parallel imports'.

11, to see the lack of regular assembly components must be complete, in order to ensure a smooth installation of the car and normal operation. Some small parts on some assembly parts are missing, usually 'parallel imports', which cause difficulties in loading. Often due to the shortage of individual gadgets, the entire assembly is scrapped.

12, look at the specifications to buy auto parts, to identify the main technical parameters, special technology to meet the requirements of use. Some fake and shoddy products have almost the same appearance as real goods, but it is not suitable to install them. It is either big or small, and it is always unsatisfactory to use, and leaves hidden dangers.

13. Look at the process The appearance of inferior products is sometimes good, but due to poor manufacturing process, cracks, sand holes, slag inclusions, burrs or bumps are prone to occur. For example, the cylinder head is squeezed and deformed. When used, it is easy to cause the seal to be abrupt and ablated, resulting in oil leakage, air leakage and water leakage. The working surface of the piston and piston ring has burrs and easy to pull the cylinder.
