Method of authenticity distinction

Domestic excavator parts are divided into original parts, supporting parts and auxiliary parts. The parts purchased by the OEM from the supporting manufacturer and sold as after-sales repair parts are called pure parts. The quality is guaranteed, but the price is expensive. The original supporting parts of the main machine are OEM parts, which are from one source and are of the same quality. Only the packaging is different, but the price is lower than that of pure parts. However, because the original factory parts and supporting factory parts are more expensive, after the warranty period of many users' cars, considering the cost issue, they often choose sub-factory parts instead. Sub-factory parts refer to the accessories produced by manufacturers not authorized by the manufacturer. It is marked with its own factory name and its own trademark, but without the manufacturer’s brand LOGO, it will write "applicable to ××, ×× models". . These auxiliary parts are generally produced by small factories, but there are also some large factories in the world.

Regarding whether the original parts should be selected as secondary parts after all, users can say that they have different opinions. Some users advocate the use of pure original parts, which can protect the machine to the greatest extent. However, some users argue that in addition to using original parts for important parts, some unimportant domestic excavator parts can also be replaced by auxiliary parts.

Judging from the price, the price of general fakes is only a fraction of the real ones. If you find that the price of the product is very different from the normal price when buying accessories, you must be more vigilant. In addition, if some businesses say that they do not include taxes and "parallel imports", they are often used as an excuse to cover up fake and inferior products and enticing people to take the bait at a low price.

Recognition is based on the packaging. The packaging of professional accessories is exquisitely manufactured. There are certain rules for color, markings, and styles, and it is generally difficult to copy the same. The packaging of the copy is relatively rough and simple to distinguish. However, some copyists rely on modern and advanced printing technology to make the parts and packaging very vivid. If they are not carefully identified, it is difficult to make a difference.

Mechanical parts generally have outer packaging and inner packaging, and the outer packaging is packed with packaging boxes and boxes; the inner packaging is generally marked packaging paper and plastic bags or paper bags. The outer packaging boxes (boxes) of pure imported accessories are all posted with manufacturers' common, clear printing, excellent paper quality, and marked with part numbers, titles, quantities, and manufacturers and countries. The copied label is not printed precisely, and the color is either light or heavy. It is difficult to combine with the pure packaging. Using computer-printed part numbers and the color marked by the manufacturer is both light and heavy. Careful identification can distinguish between authenticity and falsehood.
