Patented die to draw
pre-stressed concrete wire
The die, developed by Vassena, has a core that is well dimensioned compared to the holes; it is assembled in a fixed and
immovable way in its compact casing in standard sizes.
The pressure die, with a cylindrical hole and pointed final section of hard metal, fits perfectly into the cone entrance of the
die, permitting the removal of any lubricant solidification in the cone of the die during pauses in production. The particular
structure of the pressure core guarantees efficacy and consistency to the lubrication. The support die provides stability
and reduces vibration to the core; consequently there is less possibility of breakage and a reduction in wire vibration.
Moreover, the system VG402 is equipped with a drain hole that permits any lost lubricant, perhaps caused by an excess of
pressure, to return to the lubricant tank.
The operator can assemble die and
pressure die quickly and easily without
using special tools; the assemblage
is completed with a light manual
pressure of the two components. As
the core is assembled like a standard
die even the operation of reconditioning
is made easy, allowing for the reuse of
the system.
Using a reduction ring, die VG402
becomes a standard die.
