In recent years, the electric new energy vehicle industry has continuously improved the requirements for power, safety, comfort, lightweight and other technical indicators. The required aluminum alloy products are gradually developing in the direction of thin-wall, high-strength, low-cost and integrated structure. The development of die casting technology provides the application foundation and source power. In recent years, the development of aluminum alloy die-casting technology has generally been through continuous optimization and adjustment of alloy material components, combined with high-vacuum die-casting technology and heat treatment process parameter adjustment, and fully utilized the process characteristics of alloy materials, with the help of high-pressure injection and low-speed filling Continuously improve the comprehensive mechanical properties of die-casting alloy materials.
With the continuous deepening of military-civilian integration, a large number of ring-tube projectiles have low fatigue performance requirements. According to the integrated lightweight design of the structure, the die-casting process can be used for mass production development, which shortens the product development cycle and reduces Its production cost provides a development basis for the popularization and application of die-cast aluminum alloy.
