We are checking magnets at the beginning and end of each production run QC must perform the verification of the efficiency of the magnets.
Magnet without metallic residual - Routine inspection – visual inspection for damage and the presence of captured metal fragments
Magnet in Correct position - Magnet have to place in the middle of the line, and don't touch the walls. Between the product and magnet have to be left a gap. Taking in consideration the bed height of the product on the conveyor belt and the magnet position so is no contact
Make sure the magnet is properly positioned/ Integrity
Ferrous ball 10mm Ø - Check the efficiency of the magnet by position a calibrated reference samples of ferrous 10 mm AISI 420 on the production conveyor belt, respecting the same speed and repeating the operation for three times and in three different positions. Test should be done at the start and end of the shift. If changed magnet high, magnet efficiency must be inspected. The efficiency of the “power of attraction of the magnet “provides the capture each sample 3 times. Record the inspections carried out on the registration form
Visible check - Magnets with visible cracks or wear holes should be removed from operation immediately
Does anyone has magnet risk assessment as example to share with me?
