The FOM moduloR2C is a highly capable, modular roll-to-roll pilot line platform. The base model consists of unwind, rewind, oven and slot die stations for simple pilot-scale thin film production. The coater is based on a digitally controlled platform and provides process control and complete process data logging with export functions to enable researchers to analyse this data.  Automated documentation is key to handle large data volumes. The complete coating conditions are automatically logged by the control software and can also be printed alongside the coated area by a synchronized barcode printer/reader.  The FOM moduloR2C facilitates the integration of multiple coating and printing methods into the machine frame, for example Slot Die coating and flexographic, inkjet or rotary screen printing. In principal, any deposition method can be integrated. Designed to handle a wide range of substrates it is currently running with carbon fiber tows, multiple plastics, paper, metal foils and flexible glass.  This can be easily customized and optimized for a given coating process through the addition of a wide variety of machine modules and process stations. The integrated, extensive and self-diagnostic monitoring system with Ethernet access provides easy service support and offers remote service as well as maintenance supervision. The FOM moduloR2C makes it simple to design the perfect production line for a particular process, representing an ideal first step from R&D to full-scale fabrication. The FOM moduloR2C is capable of industrial production speed. Based on a new PLC platform the machine is Industry 4.0 ready. This allows facile reconfiguration for industrial production once your research is ready for technology transfer to a pilot or commercial phase.
