P. C. D. DIES

Synthetic Diamond dies (Polycrystalline Diamond dies)
for drawing of wires from 0.050 mm to 30.00 mm

Our polycrystalline Diamond dies production system allows us to supply dies with superior polished surface.
A better polish translates into an easier drawing operation & a higher quality finish of final product.

Technical advice for choice of PCD blanks with a wide choice of possibilities adapted to each application (Copper, Alluminium, Steel, Alloys..... etc) and taking into account your Specifications & performance requirements.

Consistency of the geometry and high level of surface polish for you to achieve the best results in terms of surface finish, tight tolerances, dies performance and to protect your lubricants. Also, get significantly longer die life.
