From NDCD die to high-cooling technology: Vassena’s latest innovations

Vassena Filiere, an Italy-based wire die manufacturer, continuously enhances its technologies to improve industrial processes in the wire sector. The company’s latest innovations include the high-cooling and the nano-diamond-coated dies, now also available in a multilayer-coated version.
3D-printed high-cooling wire drawing dies
Vassena’s 3D-printed stainless steel die is designed to optimize cooling during the wire drawing process. Thanks to an internal perforated coil, water flows through the die, ensuring uniform and rapid cooling.
The stainless steel casing with an interchangeable nib simplifies maintenance and enhances performance. This advanced technology reduces internal temperatures by 25-30°C, increasing the die’s lifespan and cutting production costs. With superior cooling capabilities and an innovative design, Vassena’s 3D-printed die offers an efficient solution for modern wire drawing needs.
Nano-diamond coated dies, now also multilayer
Vassena’s latest innovation is a multilayer nano-diamond coated die, designed for drawing high-carbon steel wire—a process previously considered impractical. This breakthrough was achieved through extensive research and development in collaboration with universities. Thanks to this synergy, the coating has been optimized to ensure high performance and greater processing efficiency.
The nano-diamond coated dies (NDCD), also available for bars and tubes up to 60 mm in diameter, use Chemical Vapor Deposition (CVD) to deliver exceptional hardness (10,000 Vickers), superior wear resistance, and an ultra-smooth surface finish. These advantages improve wire quality, enhance drawing speed, and increase heat resistance.
Compared to traditional tungsten carbide dies, NDCD variants offer a lifespan of up to 30 times longer, lower friction, and reduced lubricant and energy consumption. Manufactured using high-quality materials in collaboration with Hyperion, these dies are produced in a dedicated facility and can be customized. Thanks to these advantages, Vassena has extended nano-diamond coating to its entire range, including the VG402R pressure bushing dies, the company’s flagship product.
The future of wire drawing
3D high-cooling dies and multilayer nano-diamond coated dies represent the pinnacle of innovation in the industry. The former ensures superior performance and efficiency thanks to optimized cooling, while the latter enables the drawing of high-carbon steel wire, reducing tool wear. Together, these technologies provide an advanced solution for optimizing production and represent the future of the wire industry—an ideal choice for companies striving for maximum competitiveness.
