Key benefits

Meets all of your coatings needs

From standard to high-end applications, thick to thin films, 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

Quality application

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 manufacture. 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 recycled in a closed loop for lower cost and better environmental performance.

High precision

Sophisticated masking for high precision

Sophisticated masking technology gives you the high precision you need and ensures reproducible product quality, time after time.

In-situ layer regulation

Cross control and length control

The wire feeding rate for the boat evaporation and WEB speed is adjusted to ensure consistent layer thickness and uniformity for the batch. Layer uniformity is regulated in WEB width and WEB length.

The advanced AI evaporator is used for depositing aluminum layers in a range of 1 Ω/□ up to 100 Ω/□, 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.

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 1/100 mm to deliver high-end printing tailored to your precise product needs.

Products manufactured with the CAP machine are used for applications in e-mobility, smart grid, renewable energy, buildings 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.
