Lost Wax Casting
Lost wax casting is ideal for producing complex and high-precision railway castings with intricate shapes and fine details. It is widely applied in the manufacturing of railway couplers, signal components, and intricate brackets, ensuring excellent surface finish, dimensional accuracy, and reduced need for secondary machining compared to conventional casting methods.

Shell Molding
Shell molding is suitable for producing medium-sized railway castings that require better surface quality and tighter dimensional accuracy. It is commonly used for manufacturing railway fasteners, brake components, and gear housings, providing improved consistency and reduced machining requirements compared to traditional sand casting.

Lost Foam Casting
Lost foam casting is applied to railway components with complex geometries and integrated designs. This process eliminates the need for parting lines and allows for near-net-shape production, reducing machining costs. At Qianhao, we use lost foam casting to manufacture railway brake housings, coupler parts, and intricate structural components with reliable accuracy and durability.
