Battenfeld Parallel twin screw
Advantages of Parallel twin screws:
1.
Good at feeding,especially for powder.And also have the superiority in bad heat-stability
plastic materials and mixture palstic materials.
2.
Compare to single screw barrel,It is better than
single screw barrel in the followings: mixture materials,exhausting,self-cleaning.
3.
Compare to conical twin screw,Parallel twin screw and barrel is widely used in PVC productsprocessing, especially for the production of PVC products with theoutput over 350Kg / h, because the parallel twin-screw and barrel costsless than conical twin-
screw and barrel while it has more mature technology.
4.
Application:Parallel twin screw and barrel is successfully applied in
PVC plate,pipe, profile, pellet and mould, at the same time, it solved thetechnical problem of low foaming, high foaming, high filling, wear andcorrosion.
5.
Other advantages:Good plasticization, high productivity, small shear force, stable pressure,less wear and tear and low cost.

Basic informationRoughness of the surface | Ra0.4um |
Linearity of the screw | ≤0.015mm |
Linear axis limit | ≤0.02mm |
Hardness after Hardening & Tempering | HB240-280 |
Fragility of Nitration | ≤Two class |
Sample Screw size:106*2965mm
Apply to: PVC pipe,(add some Caco3 powder)
We nitrided the screws first,then spary bimetallic on the screw flight.
Bimetallic screw,we dig a 2915mm hole in the screw to cool when the screws are working.
And like conical twin screws,we always will dig hole in the screwaccording to your customers requsests,then plug acooper pipe into thehole. that could cool the screw when screws are on working.
