Lightweight Automobiles Have Become Another Outlet For The Automobile Manufacturing Industry. What Can A Laser Cutting Machine Do?
Automobile manufacturing has developed rapidly and has become an important global automobile sales market for several years in China. The manufacturing technology of domestic automobiles has also been continuously improved. According to the data of the China Automobile Association, the number of automobile production and sales reached 29.0154 million and 28.8789 million respectively in 2017 with a year-on-year increase of 3.19% and 3.04%.
The relevant person in charge of the China Automobile Association predicted that under the background of the weak growth of passenger cars and the decline of the growth rate of commercial vehicles in 2018, it was expected that 29.87 million vehicles would be sold in 2018, with a growth rate of 3%. The sales targets of public car companies in 2018 were generally higher than the forecast of the China Automobile Association for the market in 2018, and even 7 companies’ targets were more than 10%. In addition, many manufacturers also regarded the lightweight of vehicles as the direction of technological development.
The lightweight of automobiles is not "reducing the weight of a car" in the literal sense of the word, but rather ensuring the quality of the car, using more new materials in the functional and structural parts of the car, so that the performance of the car parts is better and lighter at the same time to ensure that vehicles travels with less energy consumption and achieve multiple effects.
At present, automotive lightweight technology is mainly achieved through the following ways: the rising proportion of lightweight materials; the application of aluminium alloys, magnesium alloys, titanium alloys, high-strength steels, plastics, powder metallurgy, ecological composites and ceramics; the increasing level of structural optimization and modular design of components, such as the use of front-wheel driving, highly rigid structures and ultra-light suspension structures to achieve lightweight , the development of computer-aided integration technology (including CAD/CAE/CAO) and structural analysis and other technologies; prompting continuous innovation in forming methods and coupling technology in the automotive manufacturing industry.
Among the above three ways to realize the lightweight of automobiles, the laser cutting machine has become an important technical means to realize the lightweight of automobiles with its unique advantages.
The laser cutting machine adopts non-contact processing. During the processing, various forms of cuttings can be achieved without touching the product, and it meets the requirements of precision and robustness in modern automobile manufacturing. For some new materials that traditional processing methods cannot achieve better results, laser cutting machines can also easily deal with them.
In contrast, the laser cutting machine has achieved a leap-forward progress in the sturdiness, seamlessness, precision and cleanliness of the connection, and will become an important forming method in the future.
In this field, the fiber laser cutting machine developed by HGLASER can be said to represent the industry level and its wide application in the automobile manufacturing industry has laid a solid foundation for the development of lightweight automobiles in China.

CIMC Vehicles Sell Well At The Guangzhou Auto Show. How To Sell Good Products In The Cold Market?
A few days ago, the 4th Guangzhou International Commercial Vehicle Exhibition was held at the Canton Fair Complex. The four manufacturing plants of CIMC Vehicles participated in the exhibition with 11 star models and sold 1,700 vehicles, which fully contributed to the adjustment of the national transportation structure. The state is making every effort to promote the adjustment of the transportation structure. CIMC Vehicles has embraced the historic development opportunity. In order to further win the battle to defend the blue sky, fight the battle against pollution, improve the comprehensive transportation efficiency and reduce the logistics cost, in recent years, the state has continuously increased the adjustment of the transportation structure. One of the important links is the management of vehicle overloading and overloading, and realizing the lightweight of vehicles. In 2016, relevant state departments issued new
