Vassena nylon drawing dies: resistant, lightweight, and durable

In today's article we analyze a very peculiar product by Vassena: the nylon drawing dies.

This innovative solution was designed and built to be a quality alternative in certain applications. In particular, thanks to the exceptional mechanical tensile strength of the synthetic polymers, the Vassena nylon drawing die is perfectly suitable for the drawing of CO2 welding wire or, in general, low carbon wires on wet drawing machines, where the tool is completely immersed in water.

The elasticity of nylon considerably reduces vibrations, thus extending the life of the dies. Furthermore, the weight of a nylon die is much lower than that of a steel product - we are talking about 70 g for nylon dies compared to 300 g for steel dies - resulting in lower transportation and storage costs.

It’s a patent: the extra-long cone drawing die VFB.4

As anticipated in our previous news article, the new Vassena VFB.4 extra-long cone die has officially been patented. When applied to the wire drawing, it allows countless benefits in terms of lubrication, wear resistance, and quality.
Thanks to a recess carved inside the die’s cone, which acts as a pressure insert, this new special tool allows to merge a die and a pressure insert in a single device.
The VFB.4 die is the latest in a series of innovations for the wire drawing world by the Italian company Vassena, which has been committed to researching and developing new materials, technologies, and geometries for over 60 years.
Vassena has always done its best to improve the processing yield and performance by working closely with drawing mills and wire & rope manufacturers, as well as raw material and machine producers.

 A new pressure die improving wire lubrication by 200%


For more than 60 years, Vassena has been working closely with wire drawing companies and rope manufacturers in order to improve the profitability of their work and results. The eye has always been to the future, looking for innovative materials, geometries and cutting-edge technologies.

In line with this path, a brand-new patent arrives today: Vassena VG402R.2
It’s a new pressure die designed to allow a superior adhesion of the lubricant on the wire, up to 200% better than standard dies. The VG402R.2 has a special structure, which allows to reduce the friction coefficient ensuring higher drawing speed, better quality of the drawn wire and longer die life. Among the other advantages there are the elimination of the candle effect in the soap box and a healthier working environment - a benefit that involves the entire company, from the entrepreneur, to the manager, from the head of the workshop to the employees and workers.


Wire drawing evolves: drawing dies 4.0 

In the last few months Vassena has been working on a brand new proprietary system: an application to generate a “dialogue” between drawing die and machine. From the very beginning, the early prototypes have shown promising results, and after the appropriate tests, the project is now a reality. The application sends signals with useful information to the software/operator for a 100% control of the finished product.

Among the collectible data are the wire temperature, the die deformation and any potential imperfection and unusual efforts, for a complete remote control of the production cycle. Vassena provides the sensors and the link to the software, developed in collaboration with one of the leading edge companies in this industry.

The solution is also compatible with all operating system. For more info, you can contact Vassena’s staff directly at:


Vassena Filiere broadens out with diamond drawing dies

The historical company Vassena Filiere located in Malgrate (Italy) begins 2019 with a big novelty: diamond drawing dies are now part of the company’s production range. 

After the introduction of pressure dies for diamond dies last month, Vassena is now able to provide the whole package: pressure dies plus diamond dies. Natural diamond dies, poly-crystalline synthetic diamond dies and mono-crystalline synthetic diamond dies, particularly suitable for the wire drawing of non-ferrous metals, can be supplied in a wide range of diameters, in order to meet all the needs of a wide customer base.

 Pressure dies for diamond dies - new in Vassena's product range

The pressure die system was developed by Vassena in order to reap the benefits of increased pressure and the consequently improved lubrication in both low and high-speed wire drawing processes.
Vassena taps into this innovative patented system applying it to polycrystalline diamond dies (PCD dies), especially designed for wire drawing of non-ferrous metals. The use of a pressure die prevents solidification of lubricant in the drawing die cone and allows an improved wire coating. The combination of these elements ensures reduced friction, less energy waste and most importantly a longer die life. Pressure dies and PCD dies can be easily and quickly assembled by operators without fuss.
