Our carbon steel investment casting provides professional and reliable manufacturing solutions for key train and railway components. Adopting high-quality carbon steel materials and advanced investment casting technology, we focus on producing high-strength, dimensionally stable and structurally precise parts that meet the strict safety and performance standards of the rail transit industry.
Each product ensures smooth surface finish, uniform internal structure, and excellent mechanical properties such as high pressure, wear, and impact resistance.
Our process excels in forming complex and irregular shapes difficult to machine via traditional methods, reducing procedures and ensuring consistency.
These cast parts are widely used in various train systems, including bogie components, connecting parts, brackets, valve bodies, transmission parts and other critical structural components. Whether for high-speed trains, locomotives or urban rail transit, our products can stably adapt to long-term operation, heavy load and complex working conditions.
We implement full-process quality control from raw material inspection to finished product testing, including dimensional verification, mechanical property testing and non-destructive testing (NDT), to ensure zero defects in key train components. With reliable quality and stable performance, our parts effectively lower maintenance costs and enhance the safety and durability of rail equipment.
