Specifications
1.bimetallic parallel twin screw and barrel
2.38CrMoAlA;
3.High quality alloy.
4.longer lifetime
Advantages:
1. Parallel twin screw and 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. Parallel twin-screw and 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 and barrel costs less than conical twin-screw and barrel while it has more mature technology.
