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 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 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 the technical problem of low foaming, high foaming, high filling, wear and corrosion.
5.Other advantages:Good plasticization, high productivity, small shear force, stable pressure,less wear and tear and low cost.

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 screw according to your customers requsests,then plug a cooper pipe into the hole. that could cool the screw when screws are on working.
