“Proud to be Taiwan's shaped die pioneer”: Weilly Diamond heads to Düsseldorf

When Weilly Diamond Industrial Co., Ltd. set out to manufacture shaped wire drawing dies back in 1990, no other Taiwanese manufacturer had gone down that road before. The company secured its place in industrial history in 1990 as the first manufacturer in Taiwan to successfully produce shaped wire drawing dies, breaking a significant technological barrier in the region. Since that milestone, Weilly Diamond has leveraged thirty years of specialized expertise to evolve into a global authority on diamond tooling.

As the industry pivots toward the next generation of manufacturing standards, the company is preparing and to showcase its advanced engineering solutions at the wire Düsseldorf 2026 exhibition (Stand 11/C06-4), Today, the company supplies wire and cable producers with precision diamond dies across Europe, the Americas, Asia and the Middle East.

Complete range of diamond dies and extrusion tools

At the exhibition, visitors will be able to explore Weilly Diamond's comprehensive portfolio, developed to meet a wide range of production requirements. The offering includes:

• Natural diamond (ND) dies for ultra-fine wire applications
• Polycrystalline diamond (PCD) dies for high-volume production
• Monocrystalline diamond (SSCD) dies for superior surface quality
• Shaped dies for non-round wire profiles
• Nano-diamond coated dies for enhanced wear resistance
• Extrusion tools for insulated wire and communication cables
• Auxiliary dies for stranding, compaction, shaving, and guiding

This broad product range allows the company to position itself as a single-source supplier for all wire drawing operations, supporting both standard and highly specialized applications.

Focus on durability and process efficiency

Weilly Diamond continues to invest in research and development to improve die performance and service life. Among its technical strengths is a proprietary diamond reinforcement process designed to increase structural stability and extend tool lifespan under high-stress conditions.

Weilly Diamond also brings strong expertise in multi-wire drawing dies, where die-set accuracy and the correct die profile are critical to stable production. Through advanced polishing and precise manufacturing control, the company helps improve surface finish, reduce wire breakage, and maintain consistent performance in multi-wire drawing operations.

Beyond Manufacturing: A Technical Expert Partnership

Weilly Diamond has built its reputation on being more than just a supplier. With ISO 9001-certified processes and a proprietary diamond reinforcement process for structural stability, the company focuses on the "total life" of the tool.

Recognizing that manufacturers often face hidden costs, Weilly offers dedicated technical support to help clients resolve common production headaches, including:

• Extending short die life through material optimization.
• Correcting inconsistent wire sizing via precision geometry.
• Eliminating frequent wire breakage through profile troubleshooting.

Weilly Diamond Industrial Co., Ltd. has successfully transitioned from a regional Taiwanese pioneer into a global powerhouse of precision engineering.
