Hi Marcus Depending on the part use and the allowable tolerances on the part you could look at etching the part numbers onto the parts. I worked for a sheet metal fabricator in the past and depending on what the part was used for and the customer requirements this was an effective solution. It’s not perfect and depending on the type of paint finish the etching isn’t always visible after the painting process. There is also the additional cost of the etching but generally this was lower than the lost time in tracing parts. Tim Hi @Tim.Berryman -Could you recall what etching product was used?
Hi Marcus I don’t have a solution for you but I am interested in following your investigations. We are going through a similar investigation at present. We have sheetmetal parts that come off the turret punch or laser cutter that then go through a folding process and for some parts also a powder coating process. Currently we use paper documents that (should) travel with the parts to identify the sheetmetal panel and the folding process required in order to call the appropriate folding program. We have already looked at laser marking a QR code that can be read by scanners when we need to identify a part. But once the panel is painted the QR code is no longer visible. We are considering a self adhesive label that can be applied after powder coating. We have considered using labels from the when the cut panels are first produced but the concern is that movement within a stack of panels may destroy the labels between the panels to a point that they are no longer readable. We are also co
