Research and Development

At  Weilly Diamond, innovation drives everything we do. Our dedicated R&D team continually develops new technologies and processes to enhance die performance, lifespan, and production efficiency for our customers.

We've made significant advancements in two key areas:

Shaped Die Polishing Technology

Weilly  is a pioneer in manufacturing shaped dies—including square, rectangular, and hexagonal profiles—with polished surface finishes comparable to those of 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.

Diamond Reinforcement Technology

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.These innovations, along with our ISO 9001-certified processes and award-winning quality standards, ensure that Weilly  continues to deliver cutting-edge solutions that optimize customer productivity and success—today and into the future.
