Punnet sealing machines, we have 4 with each having several different pattern punnet tooling, each toolset alone cost IRO £22k. The machines are IRO £100k each
One has snapped bolts and suspect parts internally do strip, assess, replace bits and order non stock parts...2 hours
Toolset mounted to machine.
Head striped exposing heater plates and mats, return springs, second pad from the right has a broken spring embedded into the plate...really embedded into the aluminium. Mind, I think there's 4 tonnes of force used every time it seals.
Damage to the spring seats and you can see one of the sheared bolt threads standing just proud between the two seats.
Drilled them out and retapaped. Alignment is critical but I've kinda got it good enough so they can still use it.
2 hours work. 40 odd bolts to remove / refit. 4 heaters, 4 thermocouples removed, 2 heater pads replaced, 3 new bolts, 34 new springs...and today I ordered £1100.00 worth of heater base plates and bits to replace the ones I've kinda bodged to get them going again...it was never a full repair, more a strip, repair what I can, assess what I need and reassemble.
