Pilot-plant for the roll-to-roll coating of flexible materials (plastic films, textile materials, metal foils) using the following technologies:

• pulsed sputtering
• DC sputtering
• plasma pre-treatment

The coFlex® 600 vacuum web coating plant can be used to deposit optical,  electrical, and decorative layers on substrates via sputtering techniques and magnetron PECVD processes. line speed of up to 100 meters per minute can be achieved.

The plant has a pretreatment unit, optical in-situ measuring units, and  several coating chambers. Thus, at Fraunhofer FEP we have available a total system for the development and pilot production of multilayer systems under near-real production conditions.

Typical substrate

• web widths up to: 700 mm
• substrate thickness: 7 ... 200 µm
• maximum outer roll diameter: 400 mm

Range of applications

• development of technologies for coating of plastic films and other flexible materials
• development of layer systems (optical, electrical and decorative functional layers and barrier layers)
• development of plasma pre-treatment processes
• development and testing of key components
• contract coating work:
• sample provision for testing and marketing purposes
• pilot production
• studies on the efficiency of coating processes
