Technical Specifications & Efficiency of Relink PCD Die Solutions
To maximize the production efficiency of copper, aluminum, and stainless steel wire drawing lines, understanding the grain structure of a premium PCD die is essential.
Relink utilizes elite polycrystalline diamond blanks with uniform diamond grain distribution. This advanced material configuration provides an exceptional cost firewall against early ring-cracking and erratic wire friction.
Our engineering team carefully calibrates the reduction angle and bearing length of each PCD die to fit high-speed drawing machines, extending the tooling lifespan up to 30 to 50 times longer than traditional tungsten carbide dies. Even under severe high-velocity tension, this precise geometry guarantees excellent surface finish optimization and minimal deviation in wire diameter.
For fine wire manufacturing ranging from 0.15mm to heavy-duty industrial rod breakdown up to 24.9mm, incorporating a Relink PCD die ensures that your line achieves the lowest possible cost-per-kilometer while drastically slashing unexpected downtime for die replacement.
