Profile: Sossner Steel Stamps manufactures precision engineered marking and decoration stamps. We also offer bar marking rolls. Wafer rolls offer the versatility to change lines of text without having to re-ingrave a solid roll for each application. The MFR series of pneumatic marking machines offers the versatility to both roll mark and stamp the product. When equipped with the optional table cylinder, the MFR series provides the cross slide action of a roll marker and the press action of a pneumatic press. The mark 25S has no ratchet to wear, no pawl to slip, and no screw to adjust.
