Vehicle identification number VIN consists of three parts, namely WMI, VDS, VIS. "WMI" is the world manufacturer's identification code, and it has the world's only vehicle manufacturing plant. The ISO organization authorizes SAE of the American Society of Automotive Engineers as its international agency and is responsible for assigning regional codes and country codes to countries around the world. It is responsible for the preservation and verification of WMI. The Auto Industry Management Office of China's Machinery Bureau has been authorized to manage the vehicle identification codes within China (including the mainland, Hong Kong, Macao and Taiwan regions) and is responsible for the allocation of WMI codes. The "VDS" section is the vehicle feature description section; "VIS" is the index part of the vehicle's delivery characteristics.
Aluminum alloy materials are widely used in all walks of life due to their low density, high strength and stiffness, good corrosion resistance, and good processing performance. At present, the proportion of aluminum alloy forging in the aluminum alloy industry is still relatively small. Due to the relatively high cost of aluminum alloy forging, the production technology is relatively difficult, and most of them are used in parts that are particularly important in stress. However, with the rapid development of the aerospace and automotive industries, the demand for aluminum alloy forgings is increasing day by day. In particular, the forgings on the aircraft account for a large proportion, mainly aluminum alloy forgings, because the aircraft has relatively high requirements for strength and weight. There is also an increasing demand for aluminum forgings in the automotive industry. Therefore, our future task is how to improve and improve the aluminum alloy forging technology to meet the increasing demands of the aluminum forging industry.
Aluminum alloy forging is relatively easy in the forging industry, and SCZY can easily deal with steel forgings, so under the condition of reasonable product structure, we can fully handle the production and service of aluminum forgings.

Since January of this year, we have noticed that many vehicles have added a column "VIN" to the vehicle's signage. This is the vehicle identification code. Just like a person's identity card, it has a unique identification of a car worldwide. Sex. When each new factory car is engraved with the VIN code, this code will be accompanied by registration, insurance, annual inspection, repair and maintenance of the vehicle, and will be loaded into the service profile of each car until it is recycled or discarded. The VIN code makes it easy to find the manufacturer, seller, and user of the vehicle. The use of VIN is an important step in China's integration with the world in vehicle manufacturing, trade, and management. After the International Organization for Standardization ISO established ISO 3780 "Road Vehicles - World Manufacturer Identification Code" in 1976, major automobile manufacturers have established their own standards and established a worldwide vehicle identification system. In 1996, China completed the approval of vehicle identification codes and issued four important standards: GB/T16735, GB/T16736, GB/T16737, and GB/T16738. These four standards are equivalent to adopting ISO standards. In 1998, the Ministry of Machinery Industry issued regulations on the use of VIN, making it a mandatory standard for the automotive industry on October 1. This has made China an extremely important first step in establishing a universal vehicle identification system.
