The magnetic formwork magnet with a rated holding force of 400 kg is a fastening device used in the production of precast concrete elements. The magnetic system allows formwork elements to be secured quickly on casting tables and simplifies their positioning, relocation and reuse. Compared with traditional solutions based on bolts, welding or other mechanical fasteners, the formwork magnet reduces working time and provides greater flexibility when arranging moulds. It is used in precast plants, repetitive production systems and applications where stable, quickly repositionable and easily reconfigurable fastening is required.
