DIEMA GmbH combines two major production branches: the surface processing of metal products, and innovative control engineering for automated equipment. Our company is the result of a consolidation between the former BES GmbH with its long years of experience and superior know-how of innovative control engineering and the former SM Stahl GmbH, the experienced experts for state-of-the-art surface processing. 

The new DIEMA is the right partner for you if you are looking for control systems and switching stations for special machines, assembly systems, handling systems, and large-scale facilities, or fully automated systems and equipment for your surface finishing processes. We are looking forward to supporting you. Contact us. Any time! If you need a solution for a type of application that is not covered in our website, please send us an inquiry via email - in 60-plus years of experience, we may well have come across a similar requirement before!
