Indicative price ranges by machine type (2026)
The table below is a budgeting starting point, in US dollars, for the bare machine before tooling, freight and commissioning. Ranges are wide because each class spans a budget-export tier and a premium-Western tier — see who sits in which tier. Treat every figure as indicative and confirm with a current quote.
| Machine | Indicative price (USD) | What it makes / does |
|---|
| Pittsburgh lockformer | $4,000 – $15,000 | The longitudinal corner seam on rectangular duct |
| TDF / TDC flange former | $8,000 – $40,000 | Integral rolled flange on rectangular duct ends |
| Duct spot welder | $3,000 – $15,000 | Resistance tack welds on panels & fittings |
| Duct stitch / seam welder | $15,000 – $60,000 | Near-continuous or gas-tight round-duct seams |
| Plasma cutter / shear / folder | $10,000 – $60,000 | Cutting and forming of sheet and blanks |
| Spiral tubeformer | $30,000 – $150,000+ | Continuous round spiral lockseam duct |
| Coil-fed auto duct line | $120,000 – $500,000+ | Coil in, finished rectangular duct out |
Indicative market ranges across budget-export and premium-Western suppliers as of 2026, in US dollars, for the bare machine before tooling, decoiler/run-out table, freight and commissioning. Not a quotation. Prices move with steel cost, currency and configuration — request a current quote for your specification.
What actually drives the price
Tier (budget-export vs premium-Western). The single biggest swing. A budget-export spiral former and a premium European one can differ several-fold for nominally the same diameter range — the difference is build quality, tolerances, lead time and the depth of support behind it.
Automation level. On lines especially, each added station — levelling, notching, punching, seam closing, corner insertion — adds cost. Buy the automation your duct mix justifies, not the highest available.
Tooling, dies and ancillaries. Decoiler, run-out table, extra dies, controlled-corrugation units and similar are real line items that the headline machine price often excludes.
Country fit. Voltage and frequency (380V/50Hz vs 60Hz export configuration), plug/breaker spec and documentation language all affect the delivered cost. See duct machine power requirements.
Freight and commissioning. Sea freight, insurance, on-site installation, operator training and a spare-parts kit can add materially to a sticker price — and a quote that omits them is not comparable to one that includes them.
Sticker price vs delivered price vs 5-year cost
Three different numbers get confused in duct-machine buying, and comparing the wrong one is the most expensive mistake:
1. Sticker (machine) price — the headline figure. Useful only if every quote you compare includes exactly the same scope, which they rarely do.
2. Delivered-and-commissioned price — machine + tooling + freight + installation + training. This is the number to compare between vendors, and the one to actually ask for.
3. Five-year total cost of ownership — delivered price plus consumables, spare parts, downtime and support over the life of the machine. A mid-priced machine with commissioning, a two-year parts kit and responsive engineering support frequently beats the cheapest sticker over five years. Work it through with the 5-year TCO model and the ROI & payback guide.
How to get an accurate number
Send each shortlisted vendor the same brief — duct type and size mix, gauge and material, your country's voltage/frequency, and your port — and ask for a delivered, commissioned price plus a two-year spare-parts list. Then compare those, not the bare machine prices. Use the 47-point buyer's checklist so nothing is missed, and read the common buying mistakes before you commit.
For SBKJ machines, you can download the spec sheets from each product page and send your brief for a delivered-and-commissioned quote — a mechanical engineer (not a salesperson) replies within 12 hours.

FAQ
How much does a spiral duct machine cost?
Indicatively US$30,000 for a basic budget-export spiral tubeformer to US$150,000+ for a premium European one, before tooling, decoiler, run-out table, freight and commissioning. The spread is driven by build quality, diameter range, cutting system and support. Ask each vendor for the delivered-and-commissioned price.
How much does an auto duct line cost?
A coil-fed auto duct line is a six-figure purchase — indicatively US$120,000 to US$500,000+ depending on automation, line length, the stations included, tooling, freight and commissioning. Total cost of ownership matters more than the sticker price on a coordinated line.
How much does a TDF flange machine or a Pittsburgh lockformer cost?
A Pittsburgh lockformer is indicatively US$4,000–15,000; a TDF/TDC flange former indicatively US$8,000–40,000 (single-head budget at the low end, duplex or premium-Western at the high end). Confirm with a current quote, as prices move.
Why don't duct machine manufacturers publish prices?
Because the real price depends on configuration — tooling, decoiler/run-out table, automation, country voltage, freight and commissioning. Two quotes for the 'same' machine differ once these are included, so reputable suppliers quote on your actual specification rather than a single misleading number.
Is a cheaper duct machine more expensive in the long run?
Often yes. The lowest sticker price usually excludes commissioning, training, a spare-parts kit and support, which resurface as downtime and scrap. Over five years a mid-priced machine with those included is frequently cheaper. Compare delivered price plus five-year total cost of ownership.
