Single Screw Barrel Feature：
- Ideal for heat and shear-sensitive materials.
- Wide processing window for a large number of shapes at the highest possible output rates.
- Large diameter feed zone provides the surface area and residence time for gentle plasticizing and a fully homogenized melt.
- Optimized L/D based on discharge diameter of the screws
