Fujian's First 7.7m All Aluminum Carriage Was Successfully Developed

Since its inception, the Lightweight Integration Division of Nanluo Corporation has been focusing on aluminum alloy bus bodies, aluminum alloy transport vehicles and bodywork as the main R&D direction, and has actively explored a lightweight product market. Under the background of the country's vigorous efforts to rectify the overload of cargo transportation, the Lightweight Division seized the rare market opportunities and reached a cooperation intention with Nanping Yanxin Logistics in September to jointly develop a 7.7-meter all-aluminum passenger vehicle.

In order to build an aluminum logistics car into an important competitive product of the Lightweight Integration Division, it quickly seized the entire aluminum logistics car market in the province, and the business unit focused on all technical backbones and worked with automotive design companies to tackle the problem. In order to improve efficiency, technical staff of the business department are stationed in Xiamen and Fuzhou to conduct on-site design and CAE analysis. In the actual production and development process, the business department took full advantage of the South Aluminum industrial chain and jointly developed molds with the technical staff of the Aluminum Aluminum Division of the company to ensure the quality of all aluminum products and deliver them on schedule; at the assembly stage of vehicles, skilled workers continued to It has explored improvements and overcome production technical problems such as large single-side welding distortion caused by the side wall profile of the carriages, and used Nanyang National Laboratory to test the welding and riveting processes to ensure link reliability of all parts of the carriage. After the technical team's intense and orderly design and first-line technicians working overtime and assembling, the development and production of carriages progressed smoothly. In late September, the 7.7-meter van-type logistics carriages completed the optimization design of drawings, and the profiles used in all-aluminum cars in October were successively squeezed and extruded. In November, it entered the assembly of all-aluminum cars and assembly of the car body. On November 17th, the car was finally completed and assembled with customers for road testing.

The 7.7-meter all-aluminum logistics compartment is an important new product for lightweight companies, with many innovations and technical highlights. The total weight of the carriage is about 1.5 tons, which is more than 25% lower than that of the steel carriage. From the perspective of economic benefit, after using the all-aluminum carriage, the fuel consumption of the logistics vehicle can be reduced by 2-3 liters per 100 kilometers, and the comprehensive transportation cost per 100 kilometers can be Save 35-45 yuan, according to the annual operation of 100,000 kilometers calculation, the entire year can save more than 40,000 yuan in transportation costs. The shipping cost saved in one year can compensate for the difference between the procurement of all-aluminium cars and steel cars. At the same time, all-aluminum logistics cars have many advantages such as corrosion resistance, easy maintenance, and high recovery and regeneration compared with ordinary logistics cars, which will effectively promote vehicle energy-saving and emission reduction and environmental protection.

The successful development of the 7.7-meter van-type logistics vehicle of the Nanyang Lightweight Integrated Division will help the business unit quickly open the lightweight product market. At the same time, it has been tempered by lightweight product R&D teams to constantly overcome many problems in the production of all-aluminum cars, explored the details of process management such as design and production convergence, and promoted the progress of follow-up product development in the Lightweight Division.
