DPM is a Direct Part Marking technology. It consists in marking directly on the product, without the need to use a label, by gouging, engraving, burning, e.g. in metal.
The first application of DPM was marking parts of space shuttles by NASA!
MGN's offer includes not only marking equipment, but also reading equipment - DPM code scanners. They are able to decode information from various surfaces, even if the print is difficult to read.
