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,Paralleltwinscrew and barrel is widely used in PVC products processing,especially for the production of PVC products with the out put over 350Kg /h, because the parallel 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,pellet and mould, at the same time, it solved the technical problem oflow 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 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 inthescrewaccording to your customers requsests,then plug acooper pipeintothehole. that could cool the screw when screws are on working.
