Double Hole Barrels

Double-hole barrels are extruder parts wherein double screws work with the sensitivity of a gearwheel, and which need to have a perfect axial parallelism.


Double-hole barrels can be produced with hole diameters within a range of Ø65-130 mm, and up to 40 in L/D rate.


With its experience of many years, ALMAK has been manufacturing barrels at this level of sensitivity.
