bimetallic twin parallel screws barrel

Bimetallic twin parallel screws barrel are widely used in producing pipe,cable,plate,profile and ect with plastic material pvc+caco3,WC pp pe and ect.

All our extruder bimetallic twin parallel screws barrel adopt the high quality 38crmoala as the basic material,but that could change if you want.

Our manufactory have been already passed the ISO 9001:2008 and SGS certificate.

We have sparying bimetallic on the surface of The twin parallel screws barrel.

Dimension Avaliable

twin parallel screws barrel---Screw Diameter : 55/2,65/2,70/2,80/2,88/2,90/2,100/2,110/2,130/2...

We also could produce unconventional parallel twin screw barrel,and our engineer could design the screw according to your plastic material and products.

And our manufactory even have many parallel twin screw barrel designs of word-famous brand: such as CINCINNATI,BATTENFELD,KRUSSMAFFEI,BAUSANO,WEBER,AMUT....

So dear customer,if you are need to change your parallel twin screw barrel recently,please contact us! we could satified you.

Technical Parameter

Advantage of parallel twin screw barrel

1.Extruder bimetallic twin parallel screws barrel has the advantage of lower rotation speed, smaller shear stress between the small screw 

2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.

3. Extruder twin parallel screws 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 barrel costs less than conical twin-screw and barrel while it has more mature technology.

4. Extruder twin parallel screws 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.
