Vassena  to attend 7th International Conference on Drawing in Poland

On March 2-4, Zakopane in Poland will host the 7th International Conference on Drawing. Organizers for this event, to be held at the Antałówka Hotel, include members of the Poland Chapter of the Wire Association International.

The Italian wire drawing dies manufacturer Vassena will be present together with its Polish agent with a table top at the conference, in order to consolidate its presence and stay close to the customers in the area.
Conference topics will include steel wire and wire products, wires and products of non-ferrous metals, management and logistics in the metal industry.


Vassena Drawing dies: open letter

 

"During the years, we have heard all kind of things about how to get a tool, nay a drawing die, that was together cheap and durable… but unfortunately a so miraculous product has never been found.

Rightly, as my father Giuseppe said, there is no great discovery to revolutionize the system, but it’s the little experiences that allow to enhance day after day, that truly make the difference.
Thanks to his experience there were several innovations in the world of drawing, just think of the cold mounted die, the mechanical wire degreaser, the pressure die, the “L” type die with long cone and more… Ideas and patents that have been adopted and modified by others over time.
Today to talk about pressure system is normal for a young professional, but old wire manufacturers still remember what kind of revolution that was, when considering speed and durability.

This is teaching us to continue to do research on new materials, supported also by our suppliers, on new types of cores, all in order to make these little improvements that allow drawing at high speeds by reducing the number of substitutions of dies, obtaining a wire with low deformations due to the stress of wire drawing.

For this reason some years ago we have developed the type “L” die which enables, thanks to a prolonged conical part, an appropriate material, a geometry studied for every single drawing step, to get those long expected results both on high resistance and on galvanized wire.
Obviously we talk about a die composed of a drawing core which is well dimensioned and firmly and irremovably embedded in a steel case, all to reduce the vibrations and consequently the breakage of the same core and able to withstand the drawing speed and obtain a high final quality with state-of-the-art drawing machines.
The cost of this die, though being higher compared to the one with a small core, gets easily reduced to zero at the end when you consider the tons of highly quality wire you produce and the number of dies you replace.

Soon we will present our newborn product, covered by international patent, a brand new pressure insert designed to increase the lubrication of the wire also at low speeds.

We thank you for the time and thank our customers for the trust they've shown in all these years.
Yours sincerely 
 
Davide Vassena

High-speed wire polishing: up to 25 m/s with the new Vassena cleaning device


Easy to use and affordable, this wire cleaning device requires no maintenance and it is able to clean the surface of wire at a speed reaching 25 meters per second.

The machine is composed of two units which rotate in opposite sense, controlled by two different motors and by an inverter to adjust the rotation speed.

Different abrasives cubes with multiple particle sizes are available; from the coarser one (36) to the finer (320), in order to meet all the customer needs.

Service  

As it is well known, for die to provide the best performance the product requires small amendments and upkeep to make best advantage of its inner core. To easily make production dies corrections, and to achieve optimum results, we are now able to offer adequate support with machinery, technology and training both for using the machines and to grind dies production.

 

 19:49 dies for wet drawing  

 

For modern extruder machines, that reach high speeds during the process, Vassena has developed a new type of spinneret, able to perform for a longer periods of time at the required higher speeds. Moreover, due to these minor changes the quality of the wire output remains at a higher spec.
 On spinneret trail 19.38, which was born to draw dry wire and lasts about four times longer, when compared with a normal spinneret produced by Vassena. The company is now happy to introduce its new version. The 19.49,  for the wet drawing of welding wire.It is a new spinneret, that is guaranteed to last three times longer than compared with the standard. For further information, do not hesitate to contact us directly.

Due to the support given by our supplier, and also our extensive  experience in the production of dies. We have succeeded in tuning this special spinneret to permit our customers to take a full advantage of performance of their modern productions chain machines. Because of this we suggest these two types of spinneret. One specifically for use in a dry wire drawing and the other wet wire drawing. Due to alterations in the production of the draw pates are able to maintain the function and quality at even highest speeds.

Vassena introduces the new patented pressure die device VG402R.1   

 

 
Vassena has the pleasure to communicate that the company is now able to introduce the new "International patent" pressure die device called VG402R.1


This is again the VG402R system with the same characteristics:
- The nib is assembled with the stainless steel case
- The gap between wire and hole of the pressure dies is about one millimeter
- The special geometry doesn't permit the solidification of the lubricant when you stop the machine

The new device VG402R.1 that Vassena has studied has been optimized to obtain more benefits:
- more pressure with the same gap and same dimension of the pressure device
- high lubrication also at low drawing speeds
- more die life, because the lubricant is more compacted on the wire, automatically there is low coefficient of friction between wire and dies
- better cooling of the wire
- less friction on wire
- and most importantly less losses of lubricant.
