Aluminum alloy die casting in the production process to consider the selection of materials, material optimization, mold development, casting, finishing and a series of difficulties, but also need to communicate directly with customers, participate in product design, these difficulties require die casting manufacturers have strong technical strength and talent reserve. In addition, the safety and protection measures in the process of aluminum alloy melting, die-casting and post-processing put forward higher requirements for the safety production technology and personnel professionalism of enterprises. Finally, the mutual involvement of vehicle manufacturers and parts manufacturers at all levels in research and development has become a trend with the increasingly obvious specialization of the global automotive industry chain, and this upstream and downstream synchronous research and development mode puts higher requirements on the independent research and development, rapid response and continuous innovation ability of parts suppliers. Therefore, new entrants in the industry are limited by the accumulation of experience, process understanding and the lack of initial research and development strength, it is difficult to have a strong competitiveness in a relatively short period of time.

Pure electric vehicles are different from traditional fuel vehicles, and the battery + motor replaces the engine as the power output system of the car. The design of electric drive system has experienced the development stage of independent, two-in-one, three-in-one and multi-in-one. The electric drive system integration more functions is the trend of The Times, the design of the electric drive housing will also be from independent to integrated design: from the split simple integration, that is, the reducer, the motor and the electric control have their own independent housing design, to the integration of the motor, the reducer housing and the integration of the three large parts of the housing. As more functions are integrated into the electric drive, more functional designs will also be superimposed on the housing. The motor, electronic control and reducer all need cooling systems, and the design of the shell needs to consider the design and layout of the cooling pipeline. This puts forward higher requirements on the product development and design ability of shell suppliers. Integrated die casting is the general trend of automobile structure simplification. The integrated die-casting body is the upgrade of lightweight technology, which reduces the number of body parts and greatly simplifies the body structure. At the same time of lightweight, simplify the supply chain links, with the advantages of reducing vehicle weight, reducing battery costs, high utilization of raw materials, reducing factory floor space and other advantages, to achieve a significant increase in vehicle assembly efficiency. With the development of high vacuum die casting process and large tonnage die casting machine, the structural parts of aluminum alloy die casting can meet the performance requirements, making such products popular in new energy vehicles.
