New energy vehicles drive the surge of aluminum demand light weight forming technology is a necessary technology
1."Made in China 2025" lists the lightweight as the core technology and common technology of many key industries. The application of liquid die forging technology is an important means to realize the lightweight of high strength and toughness aluminum matrix.

In the development roadmap of automotive technology released in 2016, liquid die forging, as a key technology to solve the structural parts of vehicle aluminum alloy chassis, has been listed in the key development direction.

Tesla, GM, Toyota, Dongfeng, China Railway, ZTE, pride, Springer and other industry top customers fully recognized and actively applied. Benefited from "made in China 2025", highway transportation (new energy), rail transit, communication, automation, health sports and other industries will maintain high-speed growth in the next 10 years. Within five years, the market scale of aluminum based lightweight products in China will exceed 200 billion yuan / year, driving the market demand of lightweight equipment to exceed 20 billion yuan / year.

2. Market analysis: China's automobile aluminum consumption in 2017 is 3.8 million tons, and it is estimated that China's automobile aluminum consumption in 2020 will be 5.1 million tons, of which the casting aluminum consumption accounts for 80%, and the market space can reach 200 billion yuan. New energy vehicles have a more urgent demand for lightweight aluminum alloy. Restricted by the weight of the power battery and the range of the power battery, it is more urgent to reduce the importance of the body than traditional cars. Traditional metal materials are not competent for new energy vehicles, and aluminum alloy is the better choice. The production of new energy vehicles is booming, and the demand for aluminum is accelerating.

3.

1.) Process technology introduction process principle: liquid die forging, namely squeeze casting, also known as melt forging in Japan. Its principle is to apply a large mechanical pressure (about 100MPa) on the liquid or semi-solid metal entering the mold cavity to make it solidify and obtain the casting by combining casting with forging. Technical advantages: the mechanical properties of liquid die forging (squeeze casting) products are significantly higher than other casting processes, close to the forging level of the same alloy, and achieve a good balance between cost and performance. It is an excellent process to realize the lightweight of structural parts. Application status: the liquid die forging (squeeze casting) process has entered the scope of large-scale industrial application in foreign countries. However, because the technology can also be widely used in the military industry, the advanced equipment technology of the process has been blocked by the patent of Yubu and other companies in Japan for a long time, and the export of large-scale equipment has been strictly controlled, As a result, the research and development of domestic equipment development and process application industry are seriously hindered.

(2.) Core equipment advantages: 1) unique technology and precise equipment stability ensure the excellent process quality; 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 reduce energy consumption. 4) the fully integrated control system well meets the customer's one-stop and customized service needs. 5) simple operation and man-machine communication design greatly improve the availability of equipment.

(3.) "High end equipment +" mode deeply fits the customer's needs, and the market demand characteristics determine that we must occupy the market high point, Through the implementation of "lightweight high-end equipment +" complete set of technical system solutions, we will establish the extended development of new products, new processes and new materials with advanced equipment as the core, supplemented by market expansion, production operation and other services, deeply meet the needs of customers, and form a new business service mode with strong vitality and competitiveness. Customer demand focus: 1) plant layout and process design under new equipment; 2) Product structure design and optimization under new process; 3) Mold design and material selection for new products; 4) Cost competitiveness and technology upgrading space under new products.
