The screw element is an important component of the extruder, and the wear resistance and corrosion resistance are important indicators for considering the service life of the screw element.
- Do/Di: The ratio of outer and inner diameters determines the average shear rate, devolatilization effect and powder feeding ability
- Do: outer diameter
- Di: Inner diameter
- a:Center distance

- Screw configuration refers to the structural composition of the extruder screw. Different combinations can meet the production requirements of different materials. The screw
configuration can achieve dispersion, shearing and other effects, and solve the requirements for uniform mixing of materials, which is of great significance to production stability.
- Different screw elements have different functional characteristics. We should choose and design the right screw elements based on different extrusion status in order to optimize the
overall comprehensive performance in the extrusion process.
- Tightly meshing screws eliminate dead zones in the entire process section through their tight, self-cleaning screw combination, resulting in high process reliability and optimized self-
