At present, there are fake and inferior products in almost all kinds of automotive accessories. Nearly one third of them have no origin or model, and their origin is unknown. There are also many parts that are re-rebuilt from scrap automotive materials. Therefore. Rongzhi automotive stamping parts have mastered some knowledge of identification of counterfeit and inferior automotive parts is very necessary.

1. Look at the packaging: When choosing automotive parts, it is easy to find the flaws in the packaging, which should be carefully identified. The original parts packaging is generally more standardized, unified standard specifications, clear and regular printing. Open the box. There are also product certificates, manufacturer's production licenses and inspector number. Some important components, such as generators, distributors, fuel injection pumps, are also equipped with instructions to guide users to use and maintain correctly. The packaging and printing of counterfeit products are relatively poor, often without three certificates or incomplete three certificates. Famous brand products often use good paper, plastic paper bags in cartons, transparent tape or a few drops of glue at the opening of cartons. Poor quality of cartons and glue and poor painting process may be counterfeit products. Therefore, it depends on whether the trademark, factory address, grade and anti-counterfeiting label on the package are true.

2. Look at the appearance: Open the packaging, the casting mould of the main products is very exquisite, the appearance is neat, the edges and corners are relatively smooth, no burrs, edges, metal light soft, flat paint, even directly casting or laser engraving on the outside of the parts of the manufacturer, printing or casting words and markings are clear and regular. The counterfeit parts generally look very rough and have large size errors, such as rust spots on new parts or cracks and aging of rubber parts. Some small joints have the phenomenon of debonding and degumming. Most of these parts have problems. Certain factory accessories are designated a certain color on the surface, and in case of other colors, they are counterfeit and inferior parts. There are also some illegal businessmen who simply process the waste parts, such as dismantling, assembling, assembling, painting and so on, and then sell them as qualified products.

3. Look at the quality of the main factory parts and components is in accordance with the design requirements for the use of qualified materials. Most of the counterfeit products are made of cheap and inferior materials. They are rough-made and jerry-built, and some even change their internal structure, resulting in potential safety hazards. Take plastic material for example, there are raw rubber and cooked rubber, raw rubber material is hard and brittle, easy to break, cooked rubber toughness is better. It is not easy to break even under external force. If the front bumper of a car is very hard, the material of the bumper is mostly made of raw rubber. The regular plastic bumper is made of cooked rubber, which is very tough and not easy to damage.

4. Look at the craft: The process of the products in the factory is very exquisite, while the counterfeit ones look very vague because of the poor manufacturing technology. Some of them will form a big gap with the original car or can not be installed at all. For parts with spray paint or coating on the surface, the genuine spray paint or coating looks very uniform, moderate thickness, very texture, and relatively smooth. The appearance of inferior products is sometimes good, but due to poor spraying process, the surface is prone to cracks, sand holes, slag inclusion, burrs or burrs, and rough gray. For example, metal castings seldom can see the joints of the die, assembly parts are processed carefully, and there are special protective devices where they are easy to knock; stamping parts are smooth and neat, lines are clear and primer is clean; rubber and plastic products are clear and clear, without any trace of manual cutting; there are many famous manufacturers on the components of electrical products. Standard and so on. The counterfeit parts have poor gloss and burrs. In some places, the coating is very thin, and the processing and assembly surface is rough.

5. Look at the certificate: Look at whether the automotive parts are "three-nothing" products. Formal automotive parts should have manufacturers, complete and standardized trademarks and product certificates. These products have some important components of good quality.
