As a leader in the development and manufacture of liquid die forging equipment in China, Guangzhou and Germany delivered a speech at the 2018 supply and demand Trading Summit of China Aluminum-Silicon processing Industry chain hosted by SMM. Guangzhou and Germany general manager of the development trend of lightweight cars and the market for in-depth analysis and discussion, a lot of practical information, you want to know the knowledge of lightweight cars all here!
1. The trend of lightening
"made in China 2025" regards lightweight as the core technology and common technology in the development of many key industries. The application of liquid die forging technology is an important means to realize the lightweight of high strength and tough aluminum base.
In the road map of automobile technology development published in 2016, liquid die forging, as a key technology to solve the structural components of vehicle aluminum alloy chassis, has been included in the key development direction. TESLA, GM, Toyota, Dongfeng, China Railway, ZTE, PRIDE, SPRINGER and other industries top customers fully recognized and actively applied.
Benefiting from "made in China 2025", highway transportation (new energy), rail transit, communications, automation, health sports and other industries will still maintain rapid growth in the next decade. In five years, the market size of aluminum-based lightweight products in China will exceed 200 billion yuan / year. Drive the market demand for lightweight equipment to exceed 20 billion yuan per year.
2. Market analysis
In 2017, the amount of aluminum used in automobile in China is 3.8 million tons, and it is estimated that the amount of aluminum used in automobile in China will be 5.1 million tons in 2020, of which casting aluminum accounts for 80%, and the market space can reach 200 billion yuan.
The demand for lightweight aluminum alloy for new energy vehicles is more urgent. Restricted by the weight of the power battery and the range of the power battery, the reduction of the importance of the body is more urgent than the traditional car. The traditional metal material is not qualified for the new energy vehicle, and the aluminum alloy is the better choice. The surge in production of new energy vehicles has accelerated demand for aluminium.

Application Mode of liquid (semi-solid) Die forging process
1. Introduction of process technology
Process principle:
Liquid die forging, that is, squeeze casting, also known as soup forging in Japan. Its principle is to apply greater mechanical pressure (about 100MPa) to the liquid or semi-solid metal entering the cavity, make it form and solidify, and obtain the casting by the method of casting and forging.
Technical advantages:
The mechanical properties of liquid die forging (squeeze casting) products are obviously higher than those of other casting processes, which are close to the level of forgings of the same alloy, and have achieved a good balance between cost and performance.
Application status:
Liquid die forging (squeeze casting) process has entered the scope of large-scale industrial application abroad, but because this technology can also be widely used in the military industry, Therefore, the advanced equipment technology of this process has been blocked by the patents of Japanese Ministry of Astronautics and other companies for a long time and strictly controlled the export of large-scale equipment, which has seriously hindered the research and development of domestic equipment development and process application industry.
2. Core equipment advantage
The main results are as follows: 1) the unique technology and accurate equipment stability ensure the excellent quality of the process.
2) low maintenance design greatly reduces the cost of service and parts replacement
3) excellent hydraulic system design ensures the reliability of product realization and greatly reduces energy consumption.
4) the fully integrated control system can meet the one-stop and customized service needs of customers.
5) the design of man-machine communication is simple and convenient, which greatly improves the availability of the equipment.
