HELIBAR® single-screw extruders
with grooved intake zone, axially or helically grooved barrel and barrier screw with shearing and mixing sections.
Advantages:
HELIBAR® extruders provide substantial process advantages over smooth-barrel extruders including:
- Higher specific throughput
- Improved melt pressure build-up
- Lower melt temperature for most resins
- Improved melt homogeneity
- Problem-free processing of wall-slipping resins
- Reduced wear
- Short residence time
- Higher overall operating efficiency and therefore improved economics
