Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw

 
Specifications
1.bimetallic parallel twin screw and barrel
2.38CrMoAlA;
3.Highquality alloy.
4.longer lifetime
Advantages:
1. Parallel twinscrew and barrel has the advantage of lower rotation speed, smaller shear  stress between thesmall screw
2. Good plasticization, highproductivity, small shear force, stable pressure , less wear and tear and lowcost.
3. Parallel twin-screw andbarrel is widely used in PVC products processing, especially for the productionof PVC products with the output over 350Kg / h, because the parallel twin-screwand barrel costs less than conical twin-screw and barrel while it has moremature technology.
