Our core expertise lies in Natural Diamond (ND) and Polycrystalline Diamond (PCD) dies for both round and shaped wire, as well as a full range of solutions including stranding dies, shaving dies, extrusion tools, wire guides, and ceramic bar extrusion dies.
What sets Weilly apart is our mastery in shaped dies—engineered with exceptional surface polish and dimensional accuracy to meet the most demanding specifications. From simple profiles to complex geometries, our dies are crafted to ensure smooth drawing, long tool life, and consistent quality.
We've grown from a small local workshop into a globally trusted manufacturer, serving clients across the United States, Mexico, Europe, Japan, Korea, India, Southeast Asia, the Middle East, and beyond.
Business Philosophy
Continuous Innovation, Value Creation, and Growth with Our Customers.
Driven by this vision, Weilly became Taiwan's first manufacturer of diamond shaped wire drawing dies in 1995—an achievement made possible through five years of dedicated R&D and the expertise of our engineering team.
We believe that true value lies in helping our customers improve efficiency and product quality. That's why our shaped dies are not only customizable but also deliver a surface polish on par with round dies, setting new standards for precision and finish in non-round profiles.
In addition to product excellence, Weilly continues to lead through technological advancement, including our proprietary diamond reinforcement technique—a breakthrough that increases pre-stress stability, enhances die protection, and extends tool life by up to 20%.
By sharing growth, creating mutual success, and staying ahead through innovation, Weilly is proud to shape progress alongside customers worldwide.
