Aulbach Automation abk Pressenbau, a specialist manufacturer of deburring presses for large castings, has relied on die clamping and changing systems from Roemheld for more than a decade. The technology plays a key role in the safe and reliable post-processing of mega and gigacastings measuring several square metres.
Used by auto manufacturers including Tesla and Volvo, megacasting replaces hundreds of individual components with single-piece aluminium structures, such as vehicle underbodies and battery housings. While simplifying production and reducing weight, these large, heavy castings place considerable demands on deburring technology.
Based in Mömlingen, Germany, Aulbach Automation employs 70 people and has specialised in deburring presses for the foundry industry since 2021. By September 2025, it had delivered 23 presses for megacastings measuring more than 3 x 2.5 m.
Aulbach specifies powered die changing systems, ball and roller bars and clamping elements from Roemheld as standard on its large-format presses.
André Pfeifer, technical project manager at Aulbach Automation, lists their benefits as precision, reliability, durability, short delivery times and co-ordinated operation, alongside the supplier’s service.
Automated die changing reduces set-up times, improves process reliability and enhances operator safety. Accurate positioning and secure clamping are essential to prevent die damage, defective components and costly production interruptions.
Hydraulic double-acting swivel clamps on the press table deliver clamping forces from 60 to 412 kN, while accommodating clamping-edge tolerances of ±1.5 mm. Their pistons rotate through 45° during the clamping stroke, allowing dies to be retracted without interference.
Inductive sensors monitor release, changeover and clamping positions, while spring-loaded overload protection and manual emergency controls provide additional safeguards. Similar 90° swivel clamps secure the press ram.
All elements are centrally supplied by a Roemheld hydraulic unit, which automatically switches to energy-saving standby during production interruptions.
