Driven by the needs of maintenance machinery and interests, there are all kinds of imported construction machinery and auto parts in the market, but the quality is uneven. High quality accessories are the basis to ensure the normal operation of mechanical equipment. At present, the imported mechanical parts in the market mainly include "import" and "localization". The imported parts include the pure parts of the complete machine factory, the high-quality parts of the professional supporting factory, the parts of the matching models produced by countries other than the complete machine factory (such as Japan, South Korea, Singapore, etc.), as well as the parts of Hong Kong, Taiwan and other regions. "Localized" parts, which are produced by regular factories and equipped with parts of imported machinery, are generally marked with the production mark of the factory. There are also some imported mechanical parts imitated by informal factories or even private workshops, which are packaged with imported pure parts or professional factories and sold as imported pure parts, which are actually fake and shoddy 名媛直播. In addition, the parts and components imported from Asian countries and regions such as South Korea, Hong Kong and Taiwan, which are not from Japan or the United States, are equipped with exquisite pure part packaging. These are collectively referred to as fakes. Although they can be used, they are far inferior to the quality requirements of the original pure parts, especially the imitation parts produced by non-standard manufacturers, which can not meet the quality requirements of pure parts and professional factory 名媛直播 in terms of material, process and function, It has an impact on the normal use and maintenance of mechanical vehicles. Therefore, it is very necessary for business and user units to identify the authenticity of imported mechanical parts.
Identify the authenticity of imported mechanical parts from the outer packaging
Identification according to the packaging is an important procedure to check the authenticity of imported accessories. The packaging of pure parts and accessories from foreign professional supporting factories is exquisite, and there are certain rules in color, pattern and style, which is generally difficult to copy. The imitation packaging is rough and easy to identify. However, some imitators rely on modern advanced printing technology to make the parts packaging very realistic. If they are not carefully identified, it is also difficult to distinguish. Imported machinery accessories generally have outer packaging and inner packaging, and the outer packaging includes packing box and packing box; Inner packaging is generally marked with packaging paper and plastic bags or paper bags. The outer packing boxes (boxes) of pure imported accessories are pasted with unified manufacturer, clear printing and excellent paper, and printed with genuine parts9 (pure parts) mark, and marked with part number, name, quantity, manufacturer and country. The imitation label printing is not fine, and the color is either light or heavy, which is difficult to be consistent with the packaging of pure parts. The part number printed by computer and the color marked by the manufacturer are either light or heavy. Careful identification can distinguish the authenticity. From the perspective of packing cases (boxes), the imported packing cases (boxes) have tight texture and clear patterns, and the marks of the manufacturer and pure parts are generally printed on the packing boxes. For example, Komatsu and genuine parts are printed on the whole packing box by Komatsu, Mitsubishi and genuine parts are printed on the whole packing box. Although these marks are also printed on the imitation packaging, the color is not correct and the pattern is not clear. In order to prevent counterfeiting, some foreign companies have anti-counterfeiting marks on their packaging labels, which can be paid attention to in identification. The inner packaging is usually paper, paper bag or plastic bag, and the packaging is printed with pure parts and company marks. The pattern, color and pattern of packaging paper are difficult to be the same as those of imitation 名媛直播.
When identifying the packaging of imported parts, it should also be noted that construction machinery and automobile manufacturers have their own professional supporting factory parts suppliers. When importing manufacturer's accessories, the packaging box has both the factory mark of the whole machine and the mark of the supporting factory. For example, the piston ring of Mitsubishi Heavy Industry is matched by RIKEN Corporation, and the Rik mark is printed on the outer packing box. But the single piston ring box inside is a flower box package marked by Mitsubishi, which is marked as Mitsubishi. The piston ring manual indicates both Mitsubishi Motor Industry Co., Ltd. and RIKEN Co., Ltd., so don't mistakenly think that the internal and external inconsistency is not a pure part.
Identify the authenticity of imported mechanical parts. Second, identify from the product quality
Identifying imported mechanical parts from product quality is the most critical link to identify the authenticity of pure parts. Driven by interests, dealers with knots assemble the imported pure parts into the whole machine, and then put the non pure parts in the packaging of pure parts to sell to the market. Therefore, the internal quality of the product must be inspected in order to confirm the authenticity of imported accessories. The identification of product quality mainly includes observation, inspection and test.
(1) Check the appearance. See whether the processing of the product appearance is fine and whether the color is normal. If there is a sample of pure parts, it can be checked by comparison. Generally, the surface of the imitation 名媛直播 is rough and the product color is not correct.
(2) Check the identification on the product. Brand marks, part numbers and specific codes are printed on pure imported parts. Some 名媛直播 are also engraved with manufacturers and producing countries. For example, the piston of Mitsubishi diesel engine in Japan is engraved with part number, group number marks a, B, C and up ↑ direction marks on the top; The model and Mitsubishi logo are cast on the inner side of the piston skirt, and the Izumi logo of the supporting factory is clear and easy to identify. Imitations are either missing or illegible, which is difficult to achieve the effect of genuine 名媛直播.
(3) Measure the size of the product through special work to see whether it meets the requirements. Some manufacturers also provide customers with measurement tools to prevent counterfeiting.
(4) Conduct performance test on 名媛直播. The authenticity of some parts cannot be identified from the appearance inspection, so special instruments are needed for inspection. For example, the performance test of fuel injector and plug shall be carried out on the test bench to detect the fuel injection pressure, fuel injection quantity, fuel injection angle, etc.
(5) Conduct physical and chemical performance test on the product. This situation is generally used when there are doubts about the internal quality of the product or problems in use. It is a method used to seek claims from the manufacturer.
Third, identify the authenticity of imported mechanical parts from the product price
The same accessories, pure parts, professional factory parts, domestic parts and imitation 名媛直播 are very different. The price of pure parts is the highest, followed by professional factories, and the price of domestic parts and imitation 名媛直播 is the lowest. Generally, the price of pure parts can exceed one or two times that of imitation parts, and some even more; Foreign professional supporting parts are slightly lower than the pure parts of the whole machine factory. The negotiated price with foreign investors shall be implemented for the accessories imported regularly in batches, and the unified catalogue price of foreign investors shall be implemented for the accessories purchased sporadically in peacetime. Sometimes foreign businessmen also have preferential prices for regular processing of accessories. The quotation of these accessories (Japanese yen or US dollar) is calculated according to the import exchange rate at that time, plus tariff, freight and miscellaneous purpose, and then converted into the unit price of accessories, which is the conventional price commonly known by people in the industry. 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 the tax reduction in the import link and the price increase of intermediate dealers will also make the price deviate from the regular price.
Identify the authenticity of imported mechanical parts. 4. Analyze according to the purchase channel
At present, there are many purchase channels, but there are no more than two aspects. One is to import directly from abroad, and the other is to buy from dealers. The quality of accessories imported directly from foreign complete machine factories and parts supporting factories is guaranteed. If the parts are purchased from dealers or re exported from Hong Kong and Macao, they should be identified according to the above methods. In addition, all mechanical parts directly imported 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, it can be judged as non imported genuine 名媛直播.
In short, there are many ways to identify the authenticity of imported mechanical parts. Do not use a single method. Take different identification methods according to different types of parts and use them comprehensively to identify the authenticity of imported parts.
