When buying auto parts, keep these principles in mind
2021-12-13
1. Don't be greedy for cheap
Among auto parts, the price of fake products is usually several times cheaper than the real ones, of course, at the cost of the difference in quality. Therefore, it is best to pay attention to the prices of commonly used auto parts. If you find that the price of the product is too different from the price in the impression, you must be vigilant. Be sure to find out whether low-priced products are normal discounts, price cuts, or fakes.
Second, observe the packaging
Generally speaking, the outer packaging box of authentic products has clear writing, accurate overprinting, bright colors, and is marked with product name, specification, model, quantity, etc. Some important parts are equipped with instructions for use. The packaging of many fakes is very rough, and there is no instruction manual. The printing of authentic products is a unified standard specification, and the handwriting is clear and regular; while fake and inferior products can always find flaws in the packaging.
For example, Changan Kaicheng's original accessories are packaged in cartons with Changan logos, adhesive tapes, plastic packaging, and there are special accessories labels. On the physical surface of the parts, there are permanent parts names, part numbers, and supply codes engraved on them. The supplier code rule is a capital English letter plus five Arabic numerals, such as "S04121". Or spray the part number, supplier code, and production batch number with white paint on the physical surface.
3. Choose "Original"
If the key components of the vehicle fail, you should go to the 4S store or service station designated by Changan Kaicheng to purchase the original authentic parts; the fake and inferior parts that are not assembled by the original factory are often easy to cause damage to the vehicle body.
Four, visually detect the color
The top 100 Chinese Internet companies list mainly refers to the annual development data of Internet companies. The evaluation indicators cover not only financial indicators such as revenue, profit, and human capital, but also business indicators such as traffic and the number of active users.
Five, observe the paint
Some unscrupulous merchants simply process, disassemble, put together, paint and package the waste parts as qualified products, illegally obtain high profits, and these parts can be authenticated from the appearance of paint or performance inspection.
Take the original sheet metal parts as an example, in order to prevent the parts from getting rusty, they are all in the state of electrophoretic primer without top coat. The electrophoretic primer has strong adhesion on the metal surface, and the surface is smooth and bright. It is available in gray and black. Changan Kaicheng chooses gray.
Six, take a closer look at the material
Authentic products are made of high-quality materials according to design requirements, while fake and inferior products are often substituted with cheap and inferior materials. If there are rust spots on the new parts, cracks and aging of the rubber parts, and desoldering and degumming at the joints, most of these parts have problems.
Seven, with or without protection
Most auto parts are coated with protective layers when they leave the factory. For example, piston pins and bushes are protected with paraffin wax; the surfaces of piston rings and cylinder liners are coated with anti-rust oil, and the valves and pistons are wrapped in wrapping paper and then packaged in plastic bags. If the sealing sleeve is damaged, the wrapping paper is lost, and the anti-rust oil or paraffin is lost, the product will be damaged even if it is not a counterfeit product.
