Hot and semi‑hot forging form steel, aluminum, or titanium alloys under high temperature and pressure. Durable dies and controlled heating enable strong, fatigue‑resistant parts used in automotive, aerospace, and industrial components.
Hot and semi‑hot forging are deformation processes in which metal is shaped under compressive loads to achieve high strength and precise geometries. In hot forging, billets are heated above recrystallization temperature, allowing maximum formability and eliminating strain hardening. Semi‑hot forging operates at slightly lower temperatures, reducing scale formation and improving surface finish and tolerances while still enabling significant shape complexity. Commonly processed materials include steel, aluminum, and titanium alloys selected for strength, toughness, and thermal stability. Tooling ,usually made of Hot Work Tool Steels, consists of robust dies, punches, inserts, and lubrication systems designed to withstand high loads, thermal cycling, and wear. Controlled heating, press force, and die design ensure accurate grain flow, low porosity, and high fatigue resistance. Key applications include automotive suspension parts, crankshafts, connecting rods, gears, aircraft structural components, and safety‑critical fasteners where superior mechanical properties and durability are essential.
