Doctor blade pilot plant in the Competence Center for Tape Casting Technology.

The tape casting technique is predestined for the production of thin, flat ceramic components. It forms the material platform for a large number of innovative components, modules and systems. These range from classic ceramic microsystems technology to battery and filtration technologies. One of our core competencies is the development of casting slurries for tape casting. The working group sees itself as a contact partner for questions concerning the processing of ceramic, glass-ceramic, functional and metal powders into tapes. In addition to slurry and process development including the accompanying analytics, the focus is also on the transfer into technological processes.

In the Competence Center for Tape Casting Technology in Hermsdorf we have the most modern equipment and systems for casting tapes in discontinuous and continuous processes and for their functionalization by pad and screen printing.

We have summarized an overview of the individual process steps of tape casting, the available tape systems and numerous application examples in our Industrial Solutions.
