Hot forging is a metal forming process where steel is heated to approximately 1000-1200°C until it reaches a glowing red-hot state, then rapidly compressed using a hydraulic or mechanical press with specialized dies to shape the metal into desired forms like rake heads; this process not only enables complex shapes but also refines the metal's internal crystal structure and creates continuous fiber flow, significantly improving the strength and durability of the final product.
