Case study

The sound of Industry 4.0

Industry: Electronics and electrical devices

Application: Coding and marking of headphone components

Material: Plastic coating


beyerdynamic develops and produces high-quality microphones and headphones for professional applications in recording studios or on stage, and as high-end models for enjoying music at home or on the road. Moreover, beyerdynamic conference systems, interpreter consoles and tour guide systems are used at events worldwide. Founded in Berlin in 1924, reestablished in Heilbronn after the war, beyerdynamic today generates annual sales of close to 60 million euros.


The production step of coating headphone diaphragms had to be fully automated to improve quality and optimize processes. beyerdynamic opted for a transfer system with robot arms. The company was looking for a coding and marking system that could be smoothly integrated into the automation process and guarantee two-way communication based on the indust-ry 4.0 standard. At the same time, the marking system shouldn’t damage the sensitive diaphragms.


beyerdynamic opted for the industry 4.0-compatible LEIBINGER JET3up CIJ printer, which comes with all interfaces required for two-way data transfer ex works – at no additional cost. The low operating costs and main-tenance-free start-up of the printer – thanks to the Sealtronic nozzle sealing technology – were also very convincing. beyerdynamic is clearly impressed: “The LEIBINGER printer has the best price-performance ratio we could find on the market.”
