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.
