MAGNETIC CLAMPING SYSTEM
CLOSED MOULD DETECTION
The MAG cycle can only be performed when a pressure build-up of the pressing force is detected. This ensures that both mould halves have 100% contact with respective magnet plates when the MAG cycle is executed.
MAGNETIC FLUX DETECTION
Release is only given if the measured magnetic flux, after magnetization, reaches the standard minimum established safety value. If not, an error is indicated.
If during the injection moulding process, the magnetic flux value decreases minimally, the machine stops immediately.
To prevent the magnetic plates from getting too hot, which reduces the total magnetic force, the magnetic plates are equipped with a temperature sensor.
When the temperature gets higher than the pre-set value, the automatic production process stops.
CURRENT DETECTION SYSTEM
During the MAG and DEMAG cycle, the current pulse is monitored by the current detection sensor.
A successful release is only reported when the set value has been reached.
MOULD DISLOCATION DETECTION
The position of the mould is monitored during production. If due to circumstances a small shift of the mould occurs, the machine stops immediately.
The proximity switch ensures that the DEMAG cycle can only be performed if the distance between the mould and the magnetic plate is less than 0.2 mm.
In addition, the automatic production process stops immediately when a distance> 0.2 mm is detected between mould and magnetic plate.
INTERFACE CONTROL SYSTEM
Only when all detection sensors are in normal operation, the fixed and movable side have been successfully magnetized, and the safety key has been placed in injection position, the automatic production process can be started. Any other condition will result in ALARM, stopping automatic operation.
The safety key is used to select set-up or production mode. To demagnetise, the LOCK and DEMAG button must be pushed simultaneously.
Demagnetisation is not possible during the automatic production process.
