First, look at the anti-counterfeiting mark of the product. There are two main types of anti-counterfeiting methods that are used more frequently: one is the anti-counterfeiting code. Some Petrol Car parts and components have a silver coating on their outer packaging or certificate of conformity, and instructions. When the coating is scratched, there will be a set of numbers, which can be sent to the manufacturer via SMS to verify the authenticity. The second is fixed coloring. The coloring of some Petrol Car parts is fixed as a special mark of its product.
Thirdly, look at the protection of Petrol Car parts. In order to prevent Great Wall Car parts from being damaged during transportation and storage, genuine products will be coated with a protective layer on the surface of the product or packaged with protective oil seals and protective covers when they leave the factory.
In addition, the surface strength or hardness of Petrol Car parts must be considered. Genuine Petrol Car parts have high design requirements, good material quality, and advanced processing technology, while counterfeit products cannot meet these conditions and have poor surface quality. You can use a hacksaw blade or other hard objects to gently scratch the surface of Petrol Car parts. If there is no scratch, it means that the hardness is high and the quality is good.
Finally, look at the production process of Great Wall Car parts. Counterfeit and shoddy Petrol Car parts have poor production technology and rough processing quality, and die-casting parts often have cracks and sand holes. The surface of Petrol Car parts dismantled from scrapped vehicles has certain wear marks.
