Technologies & Options
Precision Slot-Die Coating
Interchangeable 50–300 mm heads, angular position 8–12 o’clock, automated Z & θ fine adjustment (1 µm steps), heated head and backing roller up to 70 °C for maximum coating precision.
Modular Drying & Atmosphere Control
Pre-oven hot plates and 2000 mm hot air oven (top/bottom zones) up to 200 °C, IR/NIR-ready, process enclosure with regulated dry air ≤ 5 % RH.
Automation & Data
Intuitive control interface with recipe-based automation, stepwise sequencing (e.g., pump infuse/withdraw synchronized with web motion), live monitoring and alarm history, full parameter and climate logging, SQL database handling for process and machine parameter, OPC UA data exchange, secure remote support.
Intelligent Web Transport
Servo unwind/rewind, load-cell tension control, bidirectional web path, stop-and-go processing, air turn bars, edge guiding and corona/de-ionization for clean, repeatable handling (3″ cores, max roll Ø 500 mm / 30 kg).
Optional Integrated Printing Unit
On request, the system can be equipped with an additional printing module such as gravure, flexographic or rotary screen. It is configured in addition to slot-die coating, enabling hybrid process sequences such as multilayer coatings with integrated printing steps. Integration is tailored to customer requirements and aligned with the process layout.
Cutter & Splice Station / Support Web (Optional)
Integrated cut/insert with vacuum table for quick splicing; optional support-tape path for delicate films.
