Due to the stringent requirements for safety, durability, and lightweighting in rail transit equipment, investment casting has become the core manufacturing process for key components in the rail transit industry, thanks to its high dimensional accuracy, complex structure forming capabilities, and excellent material properties. SHENGRONG Precision Casting Company focuses on the rail transit sector, specializing in the production of key components for bogie assemblies, braking system components, traction transmission devices, and precision castings for door systems, covering a variety of applications such as high-speed trains, subways, light rails, and special-purpose rail vehicles.
With over a decade of experience in investment casting technology, we offer higher precision compared to traditional sand casting or welding processes, enabling the integrated formation of thin-walled grid structures, irregular cooling passages, and other complex features, reducing machining procedures by 30%.
