Vacuum coater for flexible roll-to-roll coatings
LEYBOLD OPTICS CAP series
Our Leybold Optics CAP series offers high quality roll-to-roll metalizing of films used in roller-type capacitors, with standard coating widths in a range of 500 to 900 mm.
Key benefits
Meets all of your coatings needs
From standard to high-end applications, thick to thin film, plain to segmented designs, thick to thin layers, pure layers or layer stacks, you can manage every conceivable combination within this one system.
Superior thermal management
The Leybold Optics SuperBias technology supports the thermal management of sensitive, thin polymer substrates while processing, increasing productivity thanks to efficient substrate cooling.
100% in-situ quality control
Our unique DISS technology monitors and controls layer profiles and the width of free margins in real time, reducing scrap and offering you a consistently high product quality.
Highlight features
Product consistency
Automated free margin evaporator delivers consistent results
Our innovative oil evaporator generates unmetalized margins in the machine direction for increased consistency in your film capacitor manufacturing. The supplied quantity of oil is automatically managed depending on the total area of free margins, the winding speed and the layer thickness, and is controlled in a closed loop for lower costs and better environmental performance.
In-situ layer regulation
Cross control and length control
The wire feeding rate for the boat evaporation and winding speed is adjusted to ensure consistent layer thickness and uniformity for the batch. Layer uniformity is regulated in film width and length.
Aluminum evaporator
Improved layer uniformity and quality
The advanced aluminum evaporator is used for depositing aluminum layers in a range of 1 Ω/cm² up to 150 Ω/cm², using the innovative arrangement and flexible height adjustment of the individual sources to optimize layer uniformity. As well as pure aluminum applications, the evaporation source can also be used simultaneously with other sources for applications with layer stacks.
Pattern printing system
Combining coating and profiles with segmented structures
All of your coatings and profiles can be combined with segmented structures by using our optional pattern printing system. Installed in a drawer for easy access, it consists of an oil evaporator, anilox and flexo roller, including sleeve. The structure of the sleeves can be manufactured down to 1/10 mm to deliver high-end printing tailored to your precise product needs.
Highly versatile
Suitable for a broad range of applications
Products manufactured with the CAP machine are used for applications in e-mobility, smart grids, renewable energy, buildings, energy transmission and many other fields. Applications include aluminum and aluminum/zinc coatings, aluminum/zinc heavy-edge coatings, silver/zinc coatings and plain, ramp or slope layer profiles.
