Ghost Markings

If you seee Ghost Markings on a device, this generally means the original markings were removed by sanding marks or bead blasting the device. A coating is then applied to make the devices look like new again. The parts you see with ghost markings just slipped by someone’s QC process after refurbishing them. This is just one reason to let Global ETS perform an external visual inspection. With our state of the art High Definition Keyence Microscope locating anomalies is easier and pictures are clear.
