Screw conveyors are used in conveying material from point “a” to “b”, across huge range of industries, whether tiny stainless augers used in pharmaceutical factory or a heavy-duty conveyor moving course industrial materials.

Having complete flexibility on the critical variables of Diameter, Shaft size, Pitch, Thickness, and grade of material (Mild carbon steel, stainless, high tensile steel, abrasion resistant plates, chromium carbide sandwich plates etc) allows design of the most effective and efficient solutions

Special formats requiring internal legs against shaft, perimeter slots or notches, are almost limitless, with Helix Flight technology. The ability to form these special format flights with cant angles or out of special materials or part revolution sections adds further capability.

Whether it’s a 2000mm diameter, 50mm thick rock auger for drilling industry or a 300mm, 5mm small auger, Helix Flight technology can handle the challenge. We understand the complexity of an auger flights; high pitch to shaft ratios, surface requirements, special needs for fitting wear teeth.

 Fortunately, with constant research and development Helix Flight is now the leading technology for cold forming of heavy thickness helices for augers avoiding preheating labour and energy costs provides a competitive advantage, as does the ability to form helices cut with lead edge in final form ready to accept teeth and other ware parts.

Helix Flight machines are used by high volume professional manufacturers who value integrity of weld and hence pile design, value maximizing load capacity per pile and also the ease and surety of installation.

With nearly 450 different applications of screw presses there are many special features which are accommodated with Helix Flight’s technology including conical shafts, cant angles, tapering diameter helix etc.

With capacity up to 6000mm in diameter and pitch of 7200mm Helix Flight technology also allows cold forming of abrasion resistant perimeter band, cant angles, special tapered lead sections and working in larger sections sizes.

There is a growth in use of abrasion resistant materials such as Hardox 500 Tuf,
Creusabro 8000 and many other materials. Being able to cold form allows delivery of helices with the original material performance characteristics without degradation through annealing processes.

Food grade brings with it requirements of ferrous contamination free, no marking, arced welds and food grade polishing. This all starts with the forming process with Helix Flight’s ferrous contamination free system.

Common to many OEM designs is large lower helix lead edges with diameters up to 2700mm and needing precision tight tolerances on helix lead edge for sweeping material off the wagon floor. This along with being able to form these items with aggressive perimeter tapers in their final cut form allow Helix Flight technology to lead this field. Remember – no tags required. Helix Flight technology enables versatility with no limitation on what kind of shaft is employed; conical, square, hexagon, stepped round shafts etc, and helices can be cut and formed flawlessly to fit the required shaft.

Providing hollow helix solutions with two helices with cant angles back to back enables a continues void through which heating or coolant can be placed to heat or cool the material being conveyed. Helix Flight’s Blank Cut Design Manager software is an integral part of this process and the competitive advantage it brings.
