Weilly  Diamond   is a pioneer in manufacturing shaped dies—including square, rectangular, and hexagonal profiles—with surface polish comparable to round dies. While shaped dies traditionally suffer from poor polishing,  Weilly's   proprietary techniques achieve mirror-like finishes, ensuring smoother wire drawing and longer tool life.

Understanding the crystal orientation of natural diamonds, our engineers grind parallel surfaces along the {111} plane to maximize durability. Furthermore, we've created a special metal-alloy matrix that firmly retains the diamond core and offers the best pre-stress, extending the die life by up to 20% over traditional dies.

At   Weilly Diamond, we specialize in custom-engineered dies tailored to unique wire profiles, specialized materials, and non-standard machinery. Whether you need precision square, rectangular, triangular, hexagonal, or other shaped dies, our expertise covers a wide range of dimensions — from ultra-fine to large sizes — with precise radius and tolerance control.
