Euroviti, Extrusion

Extrusion

Euroviti is able to provide the complete set of monoscrew extrusion composed by: screws and barrels, feeding zone sleeve plain and grooved, like triangular, trapezoidal or spiral, complete support hopper

To increase resistance against wearing and abrasion, we are able to provide screws and barrels in:

  • EUV 41 Nitrided steel
  • EUV 79 Hardened steel
  • EUV 10 Sintered steel
  • EUV 80 Sintered steel
  • EUV 90 Sintered steel

Our staff will help you in choose the most suitable steel for your application between sets:

Standard Series                             
Bimetallic Corrosion Series         
Bimetallic Strong Series               
Bimetallic Unlimited Series           

The experience acquired in this field allows us to offer our customers the study of the screw geometry to improve the plasticizing capacity, to increase the output and to improve the homogenization.
