Progressive forging with the Hatebur process forms heated steel or aluminum billets through multiple tooling stations, producing precise near‑net‑shape parts. Its durable dies and high automation make it ideal for automotive gears, hubs, bearings, and fasteners.
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.
BÖHLER W303 ISODISC is a 5% chromium steel and corresponds to material number 1.2367 (X38CrMoV5-3). This tool steel has good hot toughness as well as a very high hot hardness and resistance against heat-checkings. Compared to an X37CrMoV5-1 (material number 1.2343), the steel has an increased molybdenum content, which significantly increases its thermal resistance and thus makes it the ideal material in die closed-die forging, open-die forging and extrusion.
Read MoreBÖHLER W350 ISOBLOC is a material produced by the electroslag remelting process (ESR) which is particularly suitable for use in large casting and forging molds. Although the steel can be classified as a 5% chromium steel, the chemical composition has been chosen to provide the best possible through-hardenability without any loss of toughness or resistance against heat-checkings. These properties make the steel the perfect choice to produce very large die casting molds, for example for mega- or giga-casting.
