Advantages of Parallel twin screw:

--Good plasticization, high productivity, small shear force,stable pressure,less wear and tear and low cost.
--Good at feeding,especially for powder.And also have the superiority in bad heat-stability plastic materials and mixture palstic materials.

Applicatio of Parallel twin screws:
Parallel twin-screwand barrel is successfully applied in PVC plate,pipe,profile,pelletandmould,at the same time, it solved the technical problem of low foaming,high foaming,high filling, wear and corrosion.

Compare to single screw barrel,
It is better than single screw barrel in the followings: mixture materials,exhausting,self-cleaning.

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 maturer technology.
