A power dip stopped many presses, and restarts were slow

Needs work

The power came back almost at once, but the presses restarted one at a time in no set order.

What happenedA short power dip, likely from the grid during a heat wave, stopped many older presses. They restarted one by one in no set order, and each threw out its first parts.
Why it mattersHours of press time lost to slow restarts, plus the first parts each press threw out.
Next stepWrite a restart plan so the presses come back quickly after a power dip.

How the presses came back one by one after the power dip

The ERP logs all 11 presses stopping at 3:10 pm, then restarting one at a time over more than an hour. The dip itself lasted a moment, so nearly all the lost time came from the slow restart.

Several presses stop together as the lights flicker

The lights flicker for a moment and four presses all stop at once, then stay stopped with the lights back on. All four stop in the same second the lights flicker, so the power stopped them, not a fault on any one press.

The rush clips were packed and ready to ship early

Going well

They went straight from the press to packing and were boxed during the next day shift.

What happenedA customer's rush order of clips went straight from the press to packing, so it is ready to ship early. It was boxed with about 2 days left before it is due.
Why it mattersThe rush order was boxed and ready to ship just over a day after it came in.
How to keep it upKeep sending rush orders straight to packing once they come off the press.

Evidence

The rush clip order from the press to packing

The ERP shows when the rush order came in, when the press molded it and when it was packed. The clips were boxed under 10 hours after the last one was molded, with most of the 3 days still left.
