Once a decision is made to pull a line, the automation equipment inside it usually gets one of two outcomes: it goes to scrap by weight, or someone documents it first and recovers real value. The difference is almost entirely about what happens in the hour before teardown starts, not after.
Before the first bolt comes out
- Walk the panel and photograph every drive, PLC rack, and HMI nameplate in place, wired and labelled. Installed-and-working photos are worth more to a buyer than a photo of the same part on a pallet later.
- Note which items are duplicated across the line — matched sets of drives or I/O cards from a repeated station sell better as a lot than as singles.
- Flag anything that was replaced recently, or kept as an unused spare — that’s often the highest-value equipment on the whole line, and it’s easy to lose track of once everything is in boxes.
During teardown
- Keep each drive with its own keypad/operator panel, cables, and mounting hardware — once these get mixed into a general parts bin, matching them back up costs more than they’re worth.
- Separate “known good, running when pulled” from “unknown/faulty” as you go. Sorting this after the fact from memory is unreliable and will cost you on valuation.
- Keep enclosures, panels, and cabinets separate from the electronics if you’re getting separate quotes — metal scrap value and electronics resale value are priced completely differently.
Getting it valued
Send the nameplate photos and condition notes before anything moves — a buyer who knows exactly what’s on offer can quote a real number, not a placeholder that gets renegotiated down once the pallet arrives. For a full lot, ask whether pickup/freight is included in the offer; for mixed lots with a wide value spread, ask whether the buyer will itemize the offer by item rather than a single blended number, so you can see where the value actually sits.
