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 inbad heat-stability plastic materials and mixture palstic materials.
--Good at feeding,especially for powder.And also have the superiority inbad heat-stability plastic materials and mixture palstic materials.
Compare to single screw barrel,
It is betterthan single screw barrel in the followings: mixturematerials,exhausting,self-cleaning.
Compare to conical twin screw,
Paralleltwin-screw and barreliswidelyusedinPVCproductsprocessing,especially for the production of PVCproducts with the out put over 350Kg /h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrelwhile it has more mature technology.
Application of Parallel twin screws:
Paralleltwin-screwand barrel issuccessfully applied in PVCplate,pipe,profile,pelletandmould,at the same time, it solved thetechnical problem of low foaming,high foaming,high filling,wear andcorrosion.
