About Dieffenbacher
Dieffenbacher is a family-owned company founded in 1873, now in its fifth generation, headquartered in Eppingen (Baden-Württemberg) with a workforce of around 1,900 employees at approximately 20 locations worldwide. The company develops and manufactures hydraulic presses and complete production plants for the wood-based panel industry (particleboard, MDF, OSB, LVL, wood fiber insulation boards), for the forming of composites (SMC, LFT, HP-RTM, Ultra-RTM) and metals, as well as plants for recycling (waste wood, Fiber2Fiber and Waste2Product solutions) and energy generation (biomass power plants, waste heat boilers, heat recovery, process equipment up to 360 bar). In addition, cutting and stacking plants for SMC and prepreg (Fibercut, TopCut), MAIER size reduction technology from Bielefeld, and panel handling systems from Nastola, Finland, are offered. The EVORIS digitalization platform supports plant operators with monitoring, anomaly detection and maintenance management; the portfolio is rounded out by lifetime service, modernization, testing of hydraulic presses in accordance with DIN EN 693/289 as well as engineering and commissioning. Customers come from industries such as wood-based panels, automotive and aerospace, recycling, petrochemicals and energy supply.
