All these series are applied for the HELL engraving machines, the HELL high-speed machines, the MDC machines, the OHIO machines, and the GS machines for the electro engraving machines. The printing mesh is symemtrical. In addition to that, the slip angles and the doctor blades for the electro engraving machines can have higher wear resistance.

The structures for all these series are composed of soldering polycrystalline diamond PCD or boron nitride PCBN blades inserted on the cemented carbide substrate. They can be made according to all kinds of angles or parameters in order to satisfy evey customer’s needs.
