Casting & Drying Systems. Steel Belt Casting and Drying Systems enable the precise production of high-quality films and foils for various industries through a thermal drying process. Each product has different manufacturing processes and requires a precisely designed and coordinated system. Berndorf Band Group offers product-specific solutions and exact system calibration for safe and sustainable production.

INDIVIDUAL POLISHING LEVELS of steel belts FOR PERFECT Results. The high-quality standards in the production of films and foils require Steel Belts with specially treated surfaces. Only with steel of the highest purity class and a structureless polish, the high requirements for the precise production of optical films can be fulfilled. Berndorf Band Group is oriented to the individual requirements of end products as well as raw materials and offers Steel Belts with different surface finishes – mill finished, ground finished or polished. To protect the sensitive belt surface from contamination and damage until it is used by customers, new technologies were invented which can be removed again without residue.
