The basic applications of precision cast components in the automotive industry include key components such as engine cylinder blocks and crankshaft shells. They are manufactured through high-precision casting processes, providing strong structural support and good thermal management, laying the foundation for the performance and efficiency of automotive engines. And precision machined components, such as brake discs and steering gears, ensure the handling and safety of the car through precise processing techniques. These two technologies complement each other in the automotive industry, providing a solid foundation for the stability, reliability, and performance of automobiles。
