Spiral grooves are precision-engineered channels in annular dies that distribute polymer melt uniformly for consistent extrusion.
Spiral grooves are helical channels machined into the mandrel or body of an annular die, designed to evenly distribute molten polymer around the circumference before it exits through the die gap. They ensure uniform flow, pressure, and temperature distribution, critical for producing consistent cross-sectional profiles in extruded products like pipes, tubes, and films.

The primary function is to distribute molten polymer evenly around the die circumference, ensuring uniform wall thickness and consistent product quality in extruded items like pipes.
They help balance and reduce pressure variations by creating multiple flow paths, which minimizes defects such as weld lines and improves processing stability.
