1.extruder double screw barrel for hdpe pipe
2.38CrMoAlA+ gas nitriding
3.Longer lifetime ,competitive price.
1. Parallel twin screw and barrel has the advantage of lower rotation
speed, smaller shear stress between the small screw
2.Good plasticization, high productivity, small shear force, stable
pressure , less wear and tear and low cost.
3.Parallel twin-screw and barrel is widely used in PVC products
processing, especially for the production of PVC products with the
output over 350Kg / h, because the parallel twin-screw and barrel
costs less than conical twin-screw and barrel while it has more
bimetallic parallel twin screw and barrel
Screw structure and compression
ratio can be designed according
to different products & different output requirement.
PVC plate, pipe, profile, pellet and mould, at the same time, it
solved the technical problem of low foaming, high foaming, high
filling, wear and corrosion.
Nitride Case Depth
1)Longer time Gas Nitriding treatment
2)special anti-wear & abrasion alloy (bimetallic)
4)cobalt base alloy
6)Gh113 nickel based alloy
Wrapped up by film in wooden
T/T , L/C
25 working days
Bimetallic: much longer lifetime.
