Leybold GmbH
Bühler Leybold Optics Alzenau GmbH
Kroenert GmbH


Designed for the future and designed to perform the demanding requirements of an unlimited range of metalized films for capacitors. From standard- to high-end applications, from thick to thin films, from plain to segmented designs, from thick to thin layers, from pure layers to layer-stacks every conceivable combination can be realised in one system. Flexibility is the key of success.

CAP-M is the innovative solution of LEYBOLD OPTICS and the reference in the market for capacitor film metalizing.


  • Strong three-stage pump set – new arrangement, optimised footprint, improved performance.
  • Guide rollers for thin film applications – top surface quality, low mass moment of inertia and high life-time.
  • Plasma pre-treatment for consistent quality of substrate before processing and best product properties.
  • Free margin oil evaporator based on flash evaporation – state of the art – patented design and principle.
  • High precession pattern printing system.
  • SuperBias – electron beam gun and double side plasma post-treatment, high efficient technology for maximum heat transfer coefficient and best process conditions.
  • Long-life zinc-oven with maximum capacity.
  • DISS – Dual In-Situ Sensor – the reference in in-situ quality control.
  • In-situ closed loop layer control and monitoring.
  • Automatic process control.
  • Recipe controlled production.
  • Batch report and data-logging for quality control, process evaluation and optimisation.
  • Advanced system controller with remote service access via modem.
