What Dunkes does

Dunkes (S. DUNKES GmbH Maschinenfabrik) is a German manufacturer of custom hydraulic and servo-hydraulic press systems, founded in 1973 and headquartered in Kirchheim unter Teck, Germany. The company engineers and builds presses spanning 20 kN to 80,000 kN of force, with approximately 80% of units custom-designed to meet specific customer requirements across metal forming, forging, deep drawing, hydroforming, compression molding, stretch forming, and assembly applications. Its proprietary dugonic control platform (dugonic SERVO, dugonic HYDRA, dugonic HMI, dugonic WHEEL-SET, dugonic Betriebsdatenerfassung) provides servo position control, variable-displacement pump drive management, human-machine interface, shop floor data collection, and specialized wheel-set press control. The company also operates Europe's largest straightening centre and supplies custom hydraulic cylinders, spare parts, and press rebuild/upgrade services for all makes and models.

Dunkes serves primary customers in automotive (including EV battery press systems), defense and munitions manufacturing, aerospace, railway, and general industrial manufacturing. The firm is deepening strategic integration with Macrodyne Technologies, North America's largest hydraulic press manufacturer, with combined manufacturing, engineering, sales, and service operations across Germany, Canada, USA, and Mexico. Under new CEO Timo Kollmann (appointed July 1, 2025), Dunkes is positioning for global expansion, with a flagship 2025 partnership through Macrodyne alongside UNION Technologies to deliver a 'Factory of the Future' in Texas for 155mm artillery shell production.

Revenue is generated through direct enterprise sales of custom-engineered capital equipment (hardware sales), ancillary automation and tool/die handling systems, professional services (installation, commissioning, rebuilds, upgrades), and recurring spare parts supply. Pricing is quote-based and not publicly disclosed, reflecting the custom-engineered nature of each system. Distribution is direct to end-user manufacturers via engineering-led consultation, with no third-party intermediaries. The customer base is industrial and includes Fortune 500-level manufacturers, indicating a project-based sales cycle with large individual ticket sizes.
