[Purchase of construction machinery parts] How to choose construction machinery parts and how to identify the authenticity of imported machinery parts
How to choose construction machinery accessories
High-quality accessories are the basis for ensuring the normal operation of mechanical equipment. Due to the need for maintenance machinery and driven by profits, a variety of imported construction machinery and automobile accessories have appeared on the market, but the quality is uneven. At present, the imported machinery parts on the market mainly fall into two categories: “imported” and “domesticated”. Imported parts include genuine parts from complete machine manufacturers, high-quality parts from professional supporting factories, parts for machine models produced in countries other than complete machine manufacturers (such as Japan, South Korea, Singapore, etc.), as well as accessories from Hong Kong and Taiwan.
There are also some informal factories or even private workshops that imitate imported mechanical parts and use packaging printed with genuine imported parts or professional factories to sell them as genuine imported parts, which are actually fake and shoddy products. There are also parts imported from Asian countries and regions such as South Korea, Hong Kong, and Taiwan that are not from Japan or the United States, and are packaged with exquisite genuine parts. These are collectively called fakes. Although they can be used, they are far less pure than the original ones. The quality requirements of parts, especially the imitation parts produced by informal manufacturers, cannot meet the quality requirements of genuine parts and professional factory products in terms of materials, processes, functions, etc., which has an impact on the normal use and maintenance of mechanical vehicles, so it has a negative impact on business operations. It is very necessary for users to identify imported mechanical parts.
Imported mechanical parts can be identified from many aspects, mainly from packaging, intrinsic quality, product price and purchase channels.
How to identify the authenticity of imported mechanical parts
1. Identification from the outer packaging
Identification based on the packaging is an important procedure for testing the authenticity of imported accessories. The packaging of genuine parts and accessories from foreign professional supporting factories is exquisitely made, with certain rules in color, pattern, and style, and it is generally difficult to imitate them. The imitation packaging is relatively rough in production and easier to identify. However, some imitators rely on modern advanced printing technology to make the packaging of parts so realistic that it is difficult to distinguish them without careful identification. Imported mechanical parts generally have outer packaging and inner packaging. The outer packaging is packed with packaging boxes and packaging boxes; the inner packaging is usually a labeled packaging.Paper and plastic bags or paper bags. The outer packaging box (box) of genuine imported accessories is labeled with the manufacturer’s uniform, clear printing, high-quality paper, and is printed with the GENUINEPARTS9 (genuine parts) mark, and is marked with the part number, name, quantity, manufacturer and country.
The imitation label printing is not fine, the color is either light or heavy, and it is difficult to match the original packaging. The part number and manufacturer’s mark printed on the computer are either light or heavy. If you identify it carefully, you will be able to identify it. Can distinguish authenticity from falsehood. From the perspective of packaging boxes (boxes), imported packaging boxes (boxes) are firm in texture and have clear patterns. The packaging boxes are generally printed with manufacturer and genuine parts marks. For example, Komatsu Company prints KOMATSU on the entire packaging box. ) and genuine parts (GENUINEPARTS). Mitsubishi Corporation printed (MITSUBISHI) and genuine parts (GENUINEPARTS) on the entire packaging box. Although the imitation packaging also printed these logos, the color was incorrect and the pattern was unclear. In order to prevent counterfeiting, some foreign companies have anti-counterfeiting marks on their packaging labels, which can be paid attention to during identification. The inner packaging is usually wrapping paper, paper bags or plastic bags, with genuine parts and company logos printed on the packaging. The patterns, colors and patterns of wrapping paper are difficult to replicate with imitations.
When identifying the packaging of imported parts, you should also pay attention to the fact that engineering machinery and automobile manufacturers have their own professional parts suppliers. When importing parts from manufacturers, the packaging box will have both the mark of the complete machine manufacturer and the mark of the supporting factory. For example, Mitsubishi Heavy Industries’ piston rings are supplied by RIKEN CORPORATION of Japan, and the outer packaging box is printed with the RIK mark. But the single piston ring box inside is packaged in a flower box with Mitsubishi markings, and its mark is MITSUBISHI. The piston ring instructions indicate both Mitsubishi Motor Vehicles Co., Ltd. and Riken Co., Ltd., so do not mistakenly think that if the parts are inconsistent internally and externally, they are not genuine parts.
2. Identification based on product quality
Identifying imported mechanical parts based on product quality is the most critical link in identifying the authenticity of pure parts. Driven by profit, some dealers assemble imported genuine parts into complete machines, then package the genuine parts with non-genuine parts and sell them to the market. Therefore, the intrinsic quality of the product must be inspected to confirm the authenticity of imported accessories. The identification of product quality mainly involves observation, inspection and testing.
(1) Check the appearance. Check whether the appearance of the product is finely processed and whether the color is normal. If there are samples of genuine parts, they can be compared and checked. Generally, the surfaces of imitation products are rough and the color of the products is also incorrect.
(2) Check the logo on the product. Genuine imported parts are printed with brand marks, part numbers and specific codes. Some products are also engraved with the manufacturer and country of production. For example, the piston of Japan’s Mitsubishi diesel engine has the part number, group number mark A, B, C and UP↑ direction mark engraved on the top; the piston skirtThe model and Mitsubishi logo are cast on the inside, as well as the IZUMI logo of the supporting factory. The cast characters are clear and easy to identify. The imitation products are either missing or have blurred writing, making it difficult to achieve the effect of the original product.
(3) Measure the size of the product through special work to see if it meets the requirements. Some manufacturers also provide customers with measuring tools to prevent counterfeiting.
(4) Conduct performance tests on products. The authenticity of some parts cannot be distinguished from appearance inspection, and special instruments are required for inspection. For example, the fuel injector and injection plug must be put on the test bench for performance testing to detect the fuel injection pressure, fuel injection volume, fuel injection angle, etc.
(5) Conduct physical and chemical performance tests on the product. This situation is generally used when there is doubt about the inherent quality of the product or problems occur during use, and it is a method used to seek compensation from the manufacturer.
3. Distinguish from the product price
For the same accessories, there is a big difference between genuine parts, professional factory parts, domestic parts and imitations. Genuine parts have the highest price, followed by professional parts, and domestic parts and imitations have the lowest price. Generally, the price of genuine parts can be one or two times higher than that of imitation parts, and some are even more; parts from foreign professional supporting factories are slightly lower than genuine parts from complete machine manufacturers. Parts imported in batches on a regular basis are subject to the negotiated price negotiated with the foreign businessman, while accessories purchased sporadically are subject to the foreign businessman’s annual unified catalog price. Sometimes foreign businessmen also have preferential prices for regular processing of spare parts. The quotation of these accessories (in Japanese yen or US dollars) is calculated based on the import exchange rate at that time, plus tariffs, shipping charges, etc., and then converted into the unit price of the accessories. This is a conventional price known to industry insiders. Accessories whose price is lower than the regular price can be judged as non-genuine parts or professional factory parts. It should be noted that tax reductions in the import process and price increases by intermediate dealers will also cause the price to deviate from the regular price.
4. Analysis based on purchase channels
Currently there are many purchase channels, but there are nothing more than two aspects, one is direct import from abroad, and the other is direct import from abroad. The accessories are purchased from dealers and imported directly from foreign complete machine factories and parts and components factories, and the quality is guaranteed. If the accessories are purchased from dealers or re-exported from Hong Kong and Macao, they must be identified according to the above methods. In addition, all construction machinery parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. If you purchase accessories from an import company, you can ask them to show the above procedures. Otherwise, they can be judged as non-imported genuine products.
In short, when identifying imported mechanical parts, there are many methods. Do not use a single method. Use different identification methods according to different types of parts, and use them comprehensively to be able to identify imported parts. Authenticity.
