What is the special way to identify the parts of the car?

At present, almost in various types of car with fake and inferior products are accessories, 1/3 accessories which has nearly no origin, no type, unknown, there are many parts is to "reborn scrap car material". So. It is very necessary for automobile stamping parts to master the identification knowledge of some fake and shoddy automobile parts.

1, look at the packaging: when choosing auto parts and spare parts, it is often easy to find out the flaws from the packaging, and should be carefully identified. The original parts packaging of the original factory is generally relatively standard, unified standard specifications, and the printing character is clear and regular. Open the box. There are also product certificate, manufacturer's license and inspector number. Some important parts, such as generator, distributor, injection pump, etc., are also equipped with instructions to guide the user to use and maintain correctly. The counterfeit product packaging printing is of poor quality, often without three or three incomplete. Famous brand products often use good paper, paper boxes and plastic paper bags, cardboard openings with transparent tape or a few drops of glue adhesion. The quality of cartons and glue and the poor technology of drawing may be counterfeit products. Therefore, it is necessary to see whether the labels, sites, grades and anti counterfeiting signs on the package are true.

Look: open the package, casting mold factory is very exquisite, appearance neat, edges are smooth, without burr, flash, metal soft light, paint smooth, even directly to the manufacturers of casting or laser engraving in the external parts, printing or marking a clear and formal typefounder. And the counterfeit accessories generally look very rough, large size error, such as the discovery of new parts rust spots or rubber parts cracking, aging phenomenon. There are off, debonding junction small, such parts are usually problems. Some accessories are factory in a specified surface color, other colors for counterfeit parts. There are also some illegal businessmen to process the waste parts through simple processing, such as dismantling, assembling, spelling, collecting, painting and so on, and then selling it as a qualified product.

To see the quality of the factory parts is to use qualified materials according to the design requirements. Counterfeit products are mostly cheap and inferior materials, making rough work on workmanship, cutting off materials, and even changing internal structure, causing security risks. Take the plastic material, raw and cooked with the raw materials, hard and brittle, easily broken, glue with good toughness,. It is not easy to break even by external force. If the car front bumper is very hard, so the material is mostly rubber, plastic bumper is regular respectively, very tough, not easy to damage.

Look at the craft: the technology of the factory is very exquisite, but the counterfeit is very vague because of the poor manufacturing process. Some of them are loaded on the car, and they will also form larger gaps with the original car or simply cannot install them. For surfaces with paint or coating, the original paint or coating looks very uniform, the thickness is moderate, the texture is very good, and it is smooth. The appearance of inferior products is sometimes good, but the surface is easy to crack, sand hole, slag, burr, or edge because of poor spraying process, and it is rough and dark. For example, metal casting can be seen rarely die seams, assembly parts processing fine, easy to bump place and also a special protection device; stamping parts are smooth and orderly, clear lines, primer finish; lines for rubber and plastic products, no clear traces of artificial cutting; electrical product components have many famous manufacturers of trademarks. And the fake accessories are poor luster and burr, in some places the coating is very thin, and the processing and assembly surface is rough.

Look at the certificate: see if the auto parts are "three no" products. The regular auto parts should have the manufacturer, the complete standard trademark and the product qualification certificate. The external packing of these products is of good quality.
