bulldozer is used in engineering. It's very important to select good accessories. It can't damage the bulldozer's performance due to poor accessories. If it affects other accessories of bulldozer, it's not good. Bulldozer is a kind of engineering vehicle. There is a large-scale metal bulldozer in front of it. When it is used, it puts down the bulldozer, cuts and pushes mud, sand and stone forward. The location and The angle can be adjusted. High quality bulldozer parts are the basis to ensure the normal work of construction machinery and equipment. However, due to the needs of maintenance machinery and the drive of interests, there are various imported construction machinery parts with different quality in the market. So how to identify the authenticity of bulldozer parts?

At present, the imported construction machinery parts in the market mainly include the pure parts of the whole machine factory, the high-quality parts of the professional supporting factory, and the exquisite pure parts packaging. However, they are the parts of the non original whole machine factory transferred from South Korea, Hong Kong, Taiwan and other Asian countries and regions of China, as well as the parts imitated by some informal factories or even private workshops in China, but the imported pure parts are printed Package of parts or professional factory, sell as imported pure parts.

　　These accessories are collectively referred to as forgeries. Although they can be used, they can not meet the quality requirements of the original pure parts, especially the imitated parts produced by informal manufacturers, which can not meet the quality requirements of the pure parts and the products of professional factories in terms of material, process and function, and have an impact on the normal use and maintenance of machinery and vehicles. Therefore, for the business and user units, they can not meet the quality requirements of the original pure parts It is very necessary to identify the mouth mechanical parts.

　　Imported bulldozer accessories can be identified from many aspects, mainly from packaging, internal quality, product price and purchase channels. It is an important procedure to identify the outer package according to the package. The packaging of pure components and accessories of foreign professional supporting factories is exquisite, with certain rules for color, pattern and style, which is generally difficult to copy. The imitated packaging is rough and easy to distinguish. However, some imitators rely on the modern advanced printing technology to make the parts packaging very lifelike. It is difficult to distinguish them without careful identification. Generally, the imported mechanical parts have external and internal packaging, and the external packaging has packaging box and packaging box; the internal packaging is generally packaging paper with logo, plastic bag or paper bag.

　　The outer packing boxes (boxes) of pure imported accessories are all pasted with unified manufacturers, clear printing, excellent paper, and printed with geninearts (pure parts) mark, and marked with part number, name, quantity, manufacturer and country. But the imitated label printing is not precise, and the color is either light or heavy, which is difficult to be consistent with the pure component packaging. The part number printed by computer and the color marked by the manufacturer are not light or heavy, and the authenticity can be distinguished by careful identification.
