aifactsphere.io on Instagram: "The making process of a ship propeller begins with detailed engineering design, where hydrodynamic calculations and computer simulations determine the propeller’s size, blade shape, and pitch for maximum efficiency. Once finalized, the propeller is typically cast using molten bronze or stainless steel poured into large precision molds. After cooling, the rough casting undergoes heavy machining to achieve exact dimensions, followed by careful grinding and hand-finis
