Parallel double screw barrel set features

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

-Good at feeding powders. They’re also good at heat-stable plastics and mixed plastics.

Compared to single screw barrel,

Three things make it better than single screw barrel: compounded polymers, venting, and self-cleaning.

Compared to conical double screw barrel,

Using parallel double screw barrels to process PVC products is common, especially over 350kg/h. Because they’re cheaper and more advanced than a conical double screw barrel.

Conical double screw barrel features

It offers homogeneous plasticization and mixing, high output, stable quality, a wide range of applications, and direct moulding of PVC powders. They can adapt to any thermoplastic production line with a wide range of forming heads and auxiliary machines. Using the conical double screw barrel, you can extrude plastic pipes, plates, sheets, rods, and profiles, and pelletize various plastic powders.

Counter rotating double screw barrel application

It’s used in PVC sheets, pipes, profiles, and pellets. It solves problems like low foaming, high foaming, high filling, wear, and corrosion.
