Train and railway accessories require high-precision manufacturing. Many components are produced via investment casting, including engine parts, transmission components, clutches, universal transmission devices, main reducers, differentials, and half shafts. Additionally, critical steering and braking system accessories such as booster assemblies, steering knuckles, ball heads, steering wheels, steering rods, and booster pumps rely on this process. These parts are often made from carbon steel, high chromium steel, and alloy steel to ensure superior mechanical properties and train safety.
