HELIBAR®
is the combination of a plastification cylinder with continuous grooves and a special barrier screw.
This system was developed by Dipl.-Ing. Eberhardt Grünschloss at the "Institut für Kunststofftechnik" at the University of Stuttgart, Germany. HELIX GmbH, as an expert manufacturer, accompanied the development of HELIBAR® right from the beginning with its unique technology for machining grooves into barrels and infeed sections. Mr. Grünschloss and Extrudex licensed HELIX GmbH to distribute and promote the HELIBAR® cylinders and screws globally. Several hundred HELIBAR® units are being successfully used worldwide.
Advantages of HELIBAR®:- produces higher output
- at lower melt temperatures
- very good process stability even
with very high tool pressure - reduces wear
- and saves energy
- lower melt temperature
- short residence time
- very good homogeneity
- higher specific output
- reduced cooling
- less wear
- energy saving
- very high process stability
- no surging
- lower start-up torque
- very good self-cleaning
- high ratio of regrind possible
- Definition of the performance requirements together with our consultant
- We prepare a quotation
- Dimensioning of the HELIBAR® layout by our experts
- We manufacture quickly and precisely
- Installation of the HELIBAR® unit in your extruder or injection moulding machine

Higher Output
The comparision between HELIBAR® and conventional extruders with grooved infeed sections shows a distinct increase of the output in kg/h per screw revolution.

Saving Energy and Lowering Costs
HELIBAR® plastification units use approx. 25% less electrical power per kg of processed plastic.

Reduced Wear, Careful Processing
The typical pressure curve in a HELIBAR® cylinder shows the greatly reduced pressure in the feeding zone and the lower maximum pressure. As a result the wear is considerably reduced, losses are decreased and the process is stable.

Schematic Sketch of a HELIBAR® Plastification Unit
The HELIBAR® cylinder is undivided and characterised by the axial or helical grooves along the entire length. The HELIBAR® barrier screw with shearing and mixing sections, is matched specifically to the cylinder.
