Our polycrystalline diamond dies production system allows us to supply dies with a superior polished surface.
A better polish translates into an easier drawing operation and a higher quality finish of the final product.
Our sintering system enables you to use our polycrystalline diamond dies (PCD), in the production of steel and other hard materials, as well as in the drawing of large wire section reductions.
Esteves Group offers a wide range of polycrystalline diamond dies ranging from 0.040 mm up to 35 mm, for all kind of applications in drawing, compacting, stranding, tube and bar calibrating.
