Advantages
The automotive industry is one of the most demanding sectors in modern manufacturing, demanding material properties, dimensional accuracy, and batch consistency.
Casting technology plays a core role in the production of automotive parts, particularly in key systems such as engines, transmissions, chassis, and braking systems, fulfilling crucial functions such as load-bearing, sealing, transmission, and safety.
As vehicles evolve toward lightweight, high-performance, and new energy vehicles, higher requirements are placed on castings:
· Materials must possess high strength, wear resistance, and heat resistance.
· Processes must ensure dimensional accuracy and surface quality.
· Manufacturing must balance mass production efficiency and cost control.
Leierwo firmly believes that high-quality casting processes are the foundation for these performance and quality goals.
