bulldozer is a very common engineering vehicle on the construction site. A large-scale metal bulldozer is installed in front of the bulldozer. When it is used, it will put down the bulldozer, cut the bulldozer forward and push the sand and other stones out. Good quality bulldozer parts are the basis of ensuring the efficiency of engineering operation, so we must always maintain the bulldozer and replace the damaged parts to ensure the efficiency of our work. However, there are various bulldozer parts with different quality in the market. How can we distinguish the quality of bulldozer parts when we choose them?

　　At present, in the market, the imported construction machinery parts mainly include the parts produced by the complete machine pure parts factory and the exquisite pure parts packaging, which is a relatively good part in all aspects. However, there are many parts made by informal factories or private workshops in the packaging of imported pure parts or professional manufacturers to sell in the market as imported pure parts.

　　These accessories are collectively referred to as fakes, although they can also be used, because the quality problem is far from meeting the quality requirements of the accessories produced by the original factory. Special equipment is a lot of informal manufacturers. The existing imitation parts, quality materials, technology and functions can not meet the quality requirements of pure parts and professional manufacturers' products. The normal use and maintenance of mechanical vehicles will cause problems. Therefore, for the vehicle using units, we must be determined to purchase the quality of parts.

　　Imported bulldozer accessories can be identified through various aspects, mainly from packaging, product quality, product price and purchase channels. The external package can be identified by naked eyes, as well as the authenticity identification of imported accessories. The original pure parts and the packaging production of foreign professional parts factories are generally very exquisite, with regular colors and patterns. If the packaging is imitated, there will be certain differences, or the obvious packaging production is very rough, which is relatively easy to distinguish.

　　Of course, there are also some preventers, through modern advanced printing technology, to make the packaging of parts very lifelike, if not carefully identified, it is difficult to distinguish. However, the imported mechanical parts have the difference between the outer package and the inner package. The outer package has a packing box, a packing box, and the inner package is a packing paper with a representation, as well as plastic bags or paper bags.

　　On the outer packing box of pure imported accessories, there are unified and clear geninearts (pure parts) marks of the printing manufacturer, and the part number, name, and quantity are also marked, as well as the surviving manufacturer and the country of exit.

　　But the imitated label printing is generally not fine, the color difference will be obvious, and it will be very different from the pure part packaging. Just put them together and compare them to see if they are true or false.
