Synthetic POLYCRISTALLINE DIAMOND (PCD-) DIES:
Short survey (PDF)

Are being manufactured by exclusively using first class PCD blank qualities only (e.g. Compax/GE, Sumidia/Sumitomo), and are supplied by EDER-Austria in an outstanding quality level, meeting any demands worldwide.

PCD dies show a distinct superiority to any other kind of dies particularly when it is to draw Non-Ferrous wires, stainless steel wire and - in a thermally stable blank execution - also for refractory wire materials. Due to their distinctly better resistance to wear and availability in large raw material blank volumes, PCD dies are increasingly replacingTungsten Carbide dies in most rod breakdown and intermediate wire drawing processes and even ND dies in intermediate down to fine wire drawing applications.

PCD dies offer their best services in the bore size range between 7,60 down to about 0.50 mm Ø, while thereafter for reason of achieving a better wire-surface quality - ND dies will be the more ideal choice for finishing.

EDER-Austria, in the late 60th have not just been pioneers in making the first PCD (Compax) die, in 1980 we have also designed and manufactured the first PCD Compacting dies (supplied to the Siemens cable group then). These achievements still are a part of our ongoing success even today and available to the benefit of all our customers.
