Progressive Forging (Hatebur)

Progressive forging using the Hatebur process is a high‑speed, automated forming method for producing near‑net‑shape parts from steel or non‑ferrous alloys. The process feeds cut billets through multiple forming stations arranged in a horizontal press, where each station performs a defined step such as upsetting, preforming, bending, and final shaping. Material is heated to hot or semi‑hot forging temperatures to ensure optimal formability and controlled grain flow. Tooling, usually made of high quality Hot Work Tool Steels, consists of precision‑machined dies, punches, transfer fingers, and guiding systems, designed to withstand high loads, cyclic impacts, and thermal stress. Integrated lubrication and temperature management improve tool life and surface quality. Typical processed materials include carbon steels, alloy steels, and aluminum alloys. The Hatebur process is widely used for high‑volume production of automotive components such as gears, bearings, hubs, fasteners, and drivetrain elements, achieving excellent dimensional accuracy, mechanical performance, and material efficiency.
