The feature characteristic of Esteves Group natural diamond dies is high performance. Thanks to a careful selection of the raw material, (natural diamond stone), as well as a precise manufacturing process, Esteves Group ensures a well defined and a perfectly consistent profile.
A particular speciality found within the Esteves Group is the production of diamond dies for fine and ultra fine wire drawing (0.005mm to 0.07mm). Esteves Group has developed an innovative method for the production of the smallest diameters in order to offer a top-quality product and obtain a superior quality surface.
Esteves Group produces natural diamond dies from 0.005 to 2.00 mm and also bigger by request.
