Auto parts manufacturers: how to distinguish the authenticity of auto parts
How to distinguish the authenticity of auto parts? The following auto parts manufacturers teach you some identification methods:
1. Look at the appearance. Auto parts manufacturers have clear and regular printed or cast words and marks on the parts, while counterfeit products have a rough appearance.
2. Look at the color. Some auto parts manufacturers specify a certain color on the surface of the part. If you encounter other colors, it is a fake and shoddy part.
3. Look at the texture. The materials used by auto parts manufacturers are qualified materials used according to the design requirements, and most counterfeit products are replaced by cheap materials.
4. Look at the paint. Illegal businessmen simply process waste parts, such as disassembly, assembly, assembly, painting, etc., and then sell them as qualified products, illegally obtaining high profits.
5. Watch "Joints." If the rivets of the clutch plate are loose, the brake pipe is degummed, the electrical parts are desoldered, and the paper filter element is detached, it cannot be used.
6. Look at the signs. Auto parts manufacturers have marked some marks on some conventional parts, such as hour gear marks, piston top marks and other assembly marks, to ensure the correct installation of parts, while others cannot be purchased.
7. If there are problems such as drying, oxidation, discoloration or aging, it depends on the "storage" of auto parts. These problems may be caused by poor storage environment, long storage time, and bad materials themselves.
8. Look at the packaging. The packaging of auto parts manufacturers is generally standardized, the standard specifications are unified, and the writing is clear and formal. However, the packaging and printing of counterfeit products are relatively poor, and it is easy to find flaws from the packaging.
9. Look at the certificate. For some important parts, especially components, such as carburetors, distributors, generators, etc., auto parts manufacturers usually include instructions and certificates when they leave the factory to guide users in installation, use and maintenance. Otherwise, most of them are fake and shoddy products.
10. Look at the protective layer for easy storage and prevent parts from being bumped. There is a protective layer before the parts leave the factory. Such as bushings, large and small bearing bushes, pistons, valves, etc. Usually protected with paraffin to avoid surface damage.
11. Only when the normal assembly parts are complete and intact can the posture be stable and the operation normal. Some small parts on assembled parts are usually "parallel imports", which makes loading difficult. Often due to shortages of individual small parts, entire assemblies are scrapped.
12. Look at the specifications of purchased auto parts to find out the main technical parameters and special processes that meet the requirements of use. Some counterfeit and shoddy products have almost the same appearance as the real ones, but they are not suitable for installation, either big or small, and they are always unsatisfactory when used, leaving hidden dangers of accidents.
13. The appearance of products with poor workmanship is sometimes good, but due to poor manufacturing workmanship, cracks, sand holes, slag inclusions, burrs or protrusions are prone to appear. For example, the cylinder gasket is extruded and deformed, which can easily lead to loosening and ablation of the seal, resulting in oil, air, and water leakage; there are burrs on the working surface of the piston and piston ring, which is easy to pull the cylinder.
The above are several identification methods shared by auto parts manufacturers with you, I hope it will be helpful to you.
