Parallel twin barrel and screws are widely used in producing pipe,cable,plate,profile and ect with plasticmaterial pvc+caco3,WC pp pe and ect.
All our extruder parallel twin bimetallic screw barrel adopt the high quality 38crmoala as the basicmaterial,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 theejection of The parallel twin bimetallic screw barrel.
Dimension Avaliable
bimetallic Parallel twin barrel and screws---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 screwaccording to your plastic material and products.
And our manufactory even have many parallel twin screw barrel designs of word-famous brand: such asCINCINNATI,BATTENFELD,KRUSSMAFFEI,BAUSANO,WEBER,AMUT....
So dear customer,if you are need to change your parallel twin screw barrel recently,please contact us! wecould satified you.

Advantage of parallel twin barrel and screws
1. Extruder bimetallic parallel twin barrel and screws has the advantage of lower rotation speed, smaller shearstress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and lowcost.
3. Extruder parallel twin barrel and screws is widely used in PVC products processing, especially for theproduction of PVC products with the output over 350Kg / h, because the parallel twin screw barrel costs lessthan conical twin-screw and barrel while it has more mature technology.
4. Extruder parallel twin barrel and screws is successfully applied in PVC plate, pipe, profile, pellet and mould, atthe same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion
