               Development of a technology for selective powder binder application
               by xerography

               binder systems have almost exclusively been applied to the full surface, which   Project management

               In the Xeropul project, an efficient and flexible binder application technology
               based on the xerography principle was developed, which is particularly suit-  Project partners

               In addition to the elaboration of the process fundamentals and the pro-
               cess-specific characterization of the powder binders, the production of the
               xerography module and its integration into a prototypic preforming process
               represented key activities. It was possible to transfer binder patterns with high
               homogeneity and resolution above the requirements, while process times
               were significantly reduced. The novel technology was finally validated by man-  Federal Ministry for Economic Affairs and
