All natural diamonds are strictly selected, grinded and polished by ourselves. The production of our wire-drawing dies is based on special technical processes, which result in slighter attrition of our high-quality wire-drawing dies. Also as outcome of these special technical processes, our tungsten carbide enameling dies are characterized to have surpassing leak-tightness. Furthermore, our extrusion tips and extrusion dies are famed for their extremely high concentricity and precision.
