PCD Wire Drawing Dies
PCD dies are made from synthetic diamond particles sintered together, offering exceptional toughness and wear resistance. They are ideal for high-speed drawing and larger wire sizes, providing long service life and consistent performance. Commonly used for both ferrous and non-ferrous wires, PCD dies are widely applied in cable manufacturing, automotive, and industrial wire production, where durability and efficiency are critical.
Weilly Diamond – Trusted Manufacturer of High-Performance PCD Dies
Polycrystalline diamond is manufactured by combining diamond powder with a metallic binder under ultra-high temperature and pressure. Available in multiple mold cavity sizes and grain sizes, it is suitable for producing large-diameter drawing dies ranging from medium to coarse drawing applications. Its exceptional wear resistance and stability, coupled with WeiLi's proprietary reinforcement and polishing techniques, significantly extend mold life compared to single-crystal diamond drawing dies.
