Founded in 1990, Weilly Diamond Industrial Co., Ltd. is a Taiwanese company specialized in the design and manufacture of high-precision diamond wire drawing dies.
With more than 35 years of experience, Weilly provides a complete range of solutions, including Natural Diamond (ND), Polycrystalline Diamond (PCD), Monocrystalline (MD/SSCD), and Nano Diamond Coated dies, available in both round and shaped configurations. The company also produces stranding, shaving, extrusion, and wire guide dies to meet the requirements of various wire and cable manufacturing sectors.
Weilly’s success is driven by a philosophy of “Continuous Innovation, Value Creation, and Growth with Our Customers”. In 1995, the company became Taiwan’s first manufacturer of diamond-shaped dies, thanks to in-house R&D and technical expertise. It has also developed a diamond reinforcement technique that increases pre-stress stability and extends die life by around 20%.
Weilly’s commitment to quality has been recognized with several industry awards, including the Taiwan Excellence Award (1996) and ISO 9001 certification since 2010.
With a growing international presence, Weilly now serves wire and cable manufacturers across Europe, the United States, Mexico, Japan, Korea, India, and Southeast Asia.
