GMD has developed the Plunger & Barrel remanufacturing service since 1979 through reverse engineering, advanced materials analysis techniques and ultra-modern multi axis CNC machines, which keeps us constantly uplifting. After a very detailed visual and dimensional inspection of the barrel arrangement, a report is sent to the customer about the condition of the fuel element and the option to proceed with the remanufacturing. The “Plunger & Barrel remanufacturing service” includes fine grinding to restore cylindricity and to build a slightly oversized plunger as the original.
