The forged crankshaft industry plays a crucial role in the manufacturing of internal combustion engines, which are used in a variety of applications including automotive, marine, and industrial machinery. Forged crankshafts are essential components that convert the linear motion of pistons into rotational motion, driving the engine's power output. The forging process involves shaping metal using localized compressive forces, typically delivered by a hammer or a press. This process enhances the mechanical properties of the crankshaft, providing superior strength, durability, and resistance to fatigue compared to cast or machined crankshafts.

The primary material used in forging crankshafts is steel, often alloyed with elements such as chromium, nickel, or molybdenum to improve its mechanical properties. The process begins with heating the steel to a high temperature, making it malleable. The heated steel is then placed in a die and subjected to high pressure to form the desired shape. After forging, the crankshaft undergoes various machining processes to achieve precise dimensions and surface finishes. These processes include turning, grinding, and polishing. Heat treatment processes such as quenching and tempering further enhance the crankshaft's strength and wear resistance.

Forged crankshafts are integral to the automotive industry, where they are used in passenger vehicles, trucks, and high-performance engines. They are also vital in the marine industry for powering ships and boats, as well as in industrial applications such as generators and compressors. The demand for forged crankshafts is driven by the need for reliable and efficient engine components that can withstand high stress and operational demands. The industry continues to innovate in materials and processes to meet the evolving requirements of engine manufacturers, focusing on improving performance, reducing weight, and enhancing fuel efficiency. The forged crankshaft industry serves a global market, with production facilities located in regions with strong automotive and industrial manufacturing sectors.
