What are the functions and characteristics of the threaded elements of the twin-screw extruder?

External Thread Components for Plastic Extrusion Machines

In order to optimize the performance of each segment of the screw, different types of external thread components are employed, offering multifunctional composition. The commonly used external thread components can be divided into two main categories.

Conveying Elements, External Thread Type: The labeling convention includes a numerical indication, such as "56/56" conveying block, where the first "56" specifies the specific pitch as 56 mm, and the second "56" indicates the length as 56 mm.

Generally, with the increase in the pitch circle diameter of the external thread block, the extrusion capacity of the plastic extrusion machine increases, resulting in reduced waiting time for raw materials and decreased mixing effectiveness. The commonly referred to large pitch circle diameter corresponds to external thread blocks with a range of 1.5D to 3D. The small pitch circle diameter refers to external thread blocks with a tooth spacing close to 0.5D. The intermediate pitch circle diameter falls between the two, providing a range of external thread components.
