SECTIONAL FLIGHTS · SEGMENT SPIRALS · PRESSED
Sectional flights. Pressed, not rolled.
Sectional flights are cut from plate as an annulus and pressed into a helix; several are then welded end to end into a continuous spiral. Helicoid flighting is cold-rolled from strip. Both make a screw. Only one keeps its full material thickness at the outer edge.
Straight talk: we do not build complete screw conveyors — we make the part that does the work: the flight. Over 3 million pressed flights since 1980, every single one checked against a profile gauge. Your fabricator welds them on — a fit so close there is nothing left to correct.
Pressed sectional vs. rolled helicoid
Rolling stretches the outer circumference of the strip, so the blade thins towards the periphery. On a lightly loaded conveyor that is often acceptable and it is the cheaper route. Under abrasion it is not: the outer edge is where the material grinds, and it is exactly the part that has been made thinner. Pressed sectional flights hold constant thickness, meet DIN 15261, and are available in any grade and any size up to Ø 3000 mm and 60 mm plate.
- Constant blade thickness — the full wear reserve right out to the edge.
- Any geometry: cylindrical, conical, variable pitch, ribbon, paddle and partial segments, toothed, perforated, cranked.
- Any material: mild steel, stainless, duplex, creep-resistant, heat-resistant, Hardox, Creusabro, manganese steel.
- Exact segments over a defined opening angle instead of full turns.
One hundred per cent gauged
Each segment is checked against a profile gauge before dispatch. Pitch and seating are right before the part reaches your welder.
Frequently asked
What is the difference between a flight and a flighting?
Very little. „Flight" or „segment" refers to the single pressed piece; „flighting" or „spiral" refers to the continuous helix that results when several segments are welded end to end.
Do you supply continuous helicoid flighting?
No. We press sectional flights only — but with constant blade thickness, tight tolerances and in any material. For heavily loaded and abrasive duty that is the technically better answer.
How large can a pressed segment be?
Up to 3000 mm outside diameter and 60 mm plate thickness, made as a one-off to your dimensions.
