In the automotive industry Schober technologies offers among all rotary off and in-line converting solutions for the finishing of circuit boards, bipolar plates and membranes for fuel cells. These rotary finishing technologies include calendaring, embossing, die cutting and punching.

Rotary web finishing offers multiple advantages

CCM (Catalyst Coated Membrane), component of MEAs (Membrane Electrode Assemblies), is quite a difficult and sensitive material to process, mainly when it comes to room temperature and humidity variations. However, rotary die cutting technology has proven its efficiency during the converting and processing, when integrated in fuel cell assembly lines.

Other materials used are GDM (Gas Diffusion Layer) and PEM (Polymer Electrolyte Membrane).
