Permanent Magnetic Plate
The magnetic upper plates have a permanent magnet in the upper plate with a system of permanent magnetic coils.
Through an electric pulse the upper punches are magnetized and kept magnetised to it, without the need for continuous connection to the electrical current. This type of plate allows us to work with the assurance that the magnetisation will remain in punches in the case of power outage, thereby avoiding the problems that this would entail.
