High-quality accessories are the basis for ensuring the normal operation of construction machinery and equipment. However, due to the needs and interests of maintenance machinery, various types of imported construction machinery parts with different quality have appeared on the market.
At present, the imported engineering machinery parts mainly include the pure parts of the whole machine factory, the high-quality components of the professional supporting factory, and the exquisite pure parts packaging, but it is the non-original import and export from South Korea and Hong Kong, Taiwan and other Asian countries and regions. The parts of the whole machine factory, as well as the imitation parts of some informal factories and even private workshops in China, are printed with imported genuine parts or professional factory packaging, and are sold as genuine imported parts. These accessories are collectively referred to as defective products. Although they can be used, they are far from the quality requirements of original genuine parts. Especially for the imitation parts produced by informal manufacturers, they cannot reach pure parts and professional products in terms of materials, processes and functions. The quality requirements have an impact on the normal use and maintenance of mechanical vehicles. Therefore, it is necessary for the operating and using units to identify imported mechanical parts.
Imported mechanical parts can be identified from many aspects, mainly from the packaging, intrinsic quality, product prices and purchase channels.
Outer packaging identification
Identification based on packaging is an important procedure for verifying the authenticity of imported accessories. The packaging of genuine parts and accessories of foreign professional supporting factories is exquisitely made, and the colors, patterns and styles have certain rules, which are generally difficult to imitate. Imitation packaging is rough and easier to distinguish. However, some imitations rely on modern and advanced printing technology to make the packaging of parts very realistic, which is difficult to distinguish without careful identification. Imported machinery parts generally have outer packaging and inner packaging, and are packaged with packaging boxes and packaging boxes; the inner packaging is generally wrapped paper with packaging and plastic bags or paper bags. Genuine imported parts and packaging boxes (boxes) are affixed with uniform manufacturers, clear printing, excellent paper quality, and printed with GENUINEPARTS (plain parts) marked with part number, name, quantity and manufacturer and country. The imitation label printing is not fine, the color is not light or heavy, it is difficult to match the packaging of the pure parts. The part number printed by the computer and the color of the manufacturer's mark are not light and heavy, and the identification can be distinguished by authenticity. From the point of view of the box (box), the imported box (box) has a firm texture and a clear pattern. The box is usually printed with the manufacturer and the genuine parts. For example, Komatsu has printed Komatsu on the whole box (KOMATSU). And the genuine parts (GENUINEPARTS), Mitsubishi Corporation printed Mitsubishi (MITSUBISHI) and genuine parts (GENUINEPARTS) on the entire package, while the imitation package also printed these marks, but the color is not correct, the pattern is not clear. In order to prevent counterfeiting, some foreign companies have anti-counterfeiting marks on their packaging labels, which can be taken into account when identifying. The inner packaging is usually wrapped paper, paper bag or plastic bag with pure parts and company logo printed on the package. The pattern, color and pattern of the wrapping paper are hard to be the same.
When identifying the packaging of imported parts, it should also be noted that construction machinery and automobile manufacturers have their own suppliers of professional supporting parts. When importing the manufacturer's accessories, the package has both the whole machine factory mark and the matching factory mark. For example, Mitsubishi Heavy Industries, its piston ring is supported by RIKENCORPOé„„RATION, and the outer box is printed with the RIK mark. But the single piston ring box inside is a Mitsubishi-labeled flower box package labeled MITé„„SUBISHI. The piston ring specification is marked with Mitsubishi Motors Industrial Co., Ltd. and also with Riken Co., Ltd., so it is not a mistake to think that internal and external inconsistencies are not pure parts.
Product quality identification
Identifying imported mechanical parts from product quality is the most critical part of identifying the authenticity of genuine parts. Driven by the interests, some dealers will assemble the imported genuine parts into the whole machine, and then sell the pure parts to the non-pure parts to sell to the market. Therefore, the intrinsic quality of the product must be inspected to confirm the authenticity of the imported parts. The identification of product quality should be observed, inspected and tested. This includes the following aspects: (1) Check the logo on the product. Brand marks, part numbers, and specific codes are printed on genuine imported parts. Some products are also engraved with manufacturing plants and producing countries. For example, the piston of Japan's Mitsubishi diesel engine is engraved with the part number, grouping mark A, B, C and UP↑ direction marks on the top; the inside of the piston skirt is cast with the organic type and the Mitsubishi logo, and the IZUMI logo of the supporting factory is included. The casting is clear and easy to identify. Imitation is not a leak casting or a illegible handwriting, it is difficult to achieve the effect of authenticity.
(2) Measure the size of the product through special work to see if it meets the requirements. Some manufacturers also offer measurement tools to customers to prevent counterfeiting.
(3) Perform performance tests on the product. Some parts are still indistinguishable from the appearance inspection and need to be tested with special instruments. For example, the injector and the plug should be tested on the test bench to test the injection pressure, fuel injection amount, and fuel injection angle.
(4) Physical and chemical performance tests on the product. This is generally the method used to seek compensation from the manufacturer when there is doubt about the intrinsic quality of the product or when there is a problem with the use of the product.
price comparison
The same accessories, pure parts, professional parts, domestic parts and imitations vary widely. In general, the price of pure parts is the highest, the number of professional parts is second, and the price of domestic parts and imitations is the lowest. The price of genuine parts can exceed 1~2 times of the original parts, and some even more. The foreign professional supporting parts are slightly lower than the pure parts of the whole machine.
Regularly imported parts are executed at a negotiated price with foreign investors. Usually, sporadic purchases of accessories are subject to the annual catalogue price of foreign merchants. Sometimes foreign companies also have preferential prices for processing accessories. The quotes for these accessories (yen or US dollars) are calculated at the then import exchange rate, plus tariffs, miscellaneous fees, etc., and then converted into the unit price of the parts. If the price is lower than the conventional price, it can be judged as a non-pure or professional factory. It should be noted that the tax cuts in the import chain and the increase in the price of the intermediate dealers will also cause the price to deviate from the regular price.
Discrimination of purchase channels
There are two types of purchase channels: one is to import directly from abroad, and the other is to buy from dealers. The quality of accessories imported directly from foreign machine factories and parts supporting factories should be guaranteed. However, if it is purchased from a dealer or re-exported from Hong Kong and Macao, it will be identified according to the above method. In addition, all mechanical parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. If you purchase parts from an import company, you can ask them to show the above procedures. Otherwise, you can judge that they are not imported.
In summary, when identifying imported mechanical parts, the method can be various, and different identification methods can be adopted according to different types of accessories, and comprehensively used to identify the authenticity of imported parts.
