From 25 steel grades, from Ø 40 to 3000 mm, checked to the width of a sheet of paper. Quote within 24 hours, delivery in 5 to 10 days — and when it's urgent, considerably faster.
Laser-cut on our own machinery: the blank. Nesting software places the cuts so tightly that hardly any scrap remains — this saving goes straight into your quote.
25 steel grades are ready and waiting — pressing starts with zero lead time. Hydraulics of every size form any dimension and any material to the exact pitch: Hardox included, 60 mm included, Ø 3000 included.
Every single flight is measured on the gauge mandrel — one hundred percent, no spot checks. So at your end it is: place, weld, move on. Your welders save hours per screw.
Every flight we have pressed since 1980 is stored as a data record in our sectional flight database — to our knowledge the largest of its kind. From this data we calculate blank and pressing in advance — experience plus AI: material springback, exact blank cutting, press stroke, adapted to every geometry before the machine even starts. Your geometry has most likely been here before. We know how it presses — that's why the flight fits the first time. This head start can't be bought, only collected: 40 years, flight by flight.
No advertising promises — measurable advantages from 40 years of process work. Exactly what buyers and design engineers care about:
25 steel grades in 90 variants are ready at our works — your production starts without waiting for material. Standard in 5–10 working days, express under 24 hours. Your project doesn't wait for steel.
Anyone can buy steel — having steel in stock is the difference. Our warehouse permanently holds 25 grades in 90 dimensional variants: from 2 mm thin sheet to 60 mm heavy plate, from S235 to Hardox. Your enquiry therefore never goes to procurement — it goes straight to cutting planning — often the very same day. From there, a well-rehearsed rhythm takes over: nested laser or plasma cutting, pressing, gauge mandrel inspection, order-specific packaging with labelling. For express cases we prioritise your position at the press — turning weeks into working days and working days, if need be, into hours.
Ø 40 to 3000 mm, thicknesses from 2 to 60 mm — cylindrical, conical, progressive through cranked, notched or perforated. Ten geometries plus custom work: where standard presses give up, ours get started.
We master ten geometries in series: cylindrical, conical inside and out, progressive pitches, full-blade flights with inclination, ribbon flights, paddle and part segments, notched and perforated special flights, plus cranked versions. Add to that wear reinforcements, cut-outs, drill holes and bevels — weld-ready edges for clean V-seams (please order bevels explicitly). Via the opening angle we also produce exact segments instead of full turns. And if your drawing shows a geometry that has never existed before: that is exactly why we have development in-house — we calculate, sample and press until it fits.
S235 to S355, stainless steels 1.4301–1.4571, Duplex 1.4462, creep- and heat-resistant grades, Creusabro, Hardox — the complete spectrum from stock, special grades on request. Including advice on which material will actually survive your wear.
From structural steel S235JR and S355J2+N through the stainless grades 1.4301, 1.4307, 1.4541, 1.4401, 1.4404 and 1.4571 to Duplex 1.4462; creep-resistant grades like 16Mo3 and P265GH, heat-resistant ones like 1.4828 and 1.4841, plus the wear heroes Creusabro 4800/8000, Hardox 400 und Manganhartstahl X120Mn12 — all from stock, special grades on request. The real value is in the advice: from more than 3 million pressings we know which material will actually survive in your conveyed product — whether sand, chips, sewage sludge or material at 400 °C. Tell us what your screw conveys, and we'll tell you what your flight should be made of.
In-house laser and plasma cutting plus nesting software squeeze the maximum out of every steel plate — minimal scrap, state-of-the-art processes, sharply calculated quotes. The saving is in the process, not in the quality.
Our prices are not achieved by skimping on material, but through technology: Our own laser and plasma machinery means no subcontractor margins and no waiting at the supplier. The nesting software places your blanks so tightly on the plate that hardly any scrap remains — with Hardox that adds up to real money. And the most honest calculation comes at the end: Many customers pay a touch more with us at purchase — and save it back several times over during weld-on. Zero rework thanks to 100 % inspection means: the most expensive hours of your production stay yours. Bottom line, the C.E. flight is the more economical one.
“No part rework. No orientation. No measurement. Just fantastic.”Harry Pfeiffer · HWM Holzwärme Müllheim GmbH
