Single wire drawing lines are normally used for intermediate wire drawing, fine wire and superfine wire for specific application.

They are specially manufactured to drawing special material as plain, copper and tinned copper wire.

Sampsistemi single wire drawing machines have several advantages including:

  • Intermediate and fine wire production range
  • Easy string-up and maintenance operations thanks to full front access and ergonomic design
  • Fully submerged drawing sections
  • Additional spray lubrication available
  • Excellent wire surface quality
  • Great energy savings
  • Annealing performed in a self-generating steam atmosphere
  • Compact design
  • Large diameter annealing rings and long wire path
  • Also suitable for data and communication cables extrusion lines
  • Optional final preheater when in tandem with extrusion line
  • Optional wire temperature control
