Magnetic clamp systems are of great significance to plant construction and to mechanical engineering, and their purpose is to secure, cover and assist in the assembly of applications involving systems that require unusually high levels of clamping force. This is achieved by direction of the magnetic flux by means of 'pole shoes', rather than simply distributing flux evenly around the magnet. This directs the flux so that it emerges at a desired location and is able to exert its impact there: this is particularly effective due to the high level of concentration of force at a local point or points. On contact with the mating part, the clamping force is many times higher, with an air gap, than it is on systems with open magnets. Thanks to this enhanced mounting capability, applications are easier to transport and secure.
