Krauss Maffei KMD parallel twin screw barrel

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,Paralleltwinscrewand barrel is widely used in PVC products processing,especially for theproduction of PVC products with the out put over 350Kg /h, because theparallel twin-screw and barrel costsless than conicaltwin-screw and barrel while it has more mature technology.
4.Application:Parallel twin screw and barrel is successfully applied in PVC plate,pipe,profile,pelletand mould, at the same time, it solved the technical problem oflowfoaming, 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 information
Roughness 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 inthescrewaccordingto your customers requsests,then plug acooper pipeintothehole. thatcould cool the screw when screws are on working.
