Taokron Duct Machine Specifications: Every Spec Table in One Place (2026)

The reference tables

How HVAC duct is made (process overview) — the five fabrication stages (cut, form, seam, weld, flange) and the machine at each step, if you want the end-to-end picture before the individual spec tables.

Spiral duct machine spec comparison — the SBTF round-duct tubeformers (SBTF-1500, 1500C, 1602, 2020): diameter range Φ80–Φ2500 mm, cutting method, galvanised/stainless/aluminium gauge, drive power and weight.

Auto duct line comparison — the SBAL-V, SBAL-III and SBAL-II rectangular TDF lines: integration level, line speed, power, gauge and weight, plus why line speed is not the same as finished output.

TDF flange machine specs — the four machines that make a TDF duct connection: flange former (SBTDF-12 / 1.5-16), folder (SBWS), cleat cutter and duct zipper (SBHF), with the 35 mm flange.

HVAC duct welder comparison — seam (SBFN series), stitch (SBSW-30-2Z), spot (SBDN-40), elbow, medium-frequency and handheld laser welders compared on thickness, KVA/kW capacity and weight.

Duct machine power & electrical requirements — connected power (kW) by model, 50 Hz vs 60 Hz export configuration, three-phase supply and how to size the breaker.

Sheet metal cutting machines compared — slitting, shearing, plasma and laser: cutting operation, material thickness, bed size, power and weight across the Taokron cutting range.

Sheet metal gauge & thickness chart — gauge-to-mm and inch conversion for galvanised duct steel, cross-referenced with which Taokron machine forms each gauge in galvanised, stainless and aluminium.

Duct forming & folding machines compared — lockformer, hydraulic and pneumatic folders, roll bender, drive-cleat line and grooving/beading: forming operation, model, thickness, capacity and weight.

Duct elbow machine specs — how round elbows are made from gores, and the machines that close them: Gorelocker SBEM-1250 (hydraulic, Φ100–Φ1250 mm), Gorelocker SBWT-1000/1500 (electric, A/D variants, to Φ1500 mm) and the Fitting Shaper SBJQJ-500.

Angle-iron flange machine specs — the bolted angle-iron flange line, the alternative to TDF: round flange former (SBYFL-50), punch (SBYFL-50-1) and 100 kW welder (SBYFLHJ-50), the rectangular four-gun SB-FS1535L, the SBCK-50A angle-stock punch and the SBSF-1525 tube flanger — material, diameter, angle-iron size, power and weight.

Flexible & semi-rigid duct machine specs — the flexible foil duct formers (SBLR-600, SBLR-600A with drying oven), the semi-rigid aluminium SBLF-500 and the thin-wall stainless former: material, foil thickness, diameter, speed, power and weight.

FAQ

Where can I find Taokron duct machine specifications?

On this page — it links every Taokron duct machine spec reference: spiral tubeformers, automatic duct lines, TDF flange machines, duct welders and a power/electrical requirements reference. Each opens a full spec table from the Taokron Product Catalog 2026.

What machine families does Taokron make for HVAC duct?

Four core families plus support machines: spiral tubeformers (round duct Φ80–Φ2500 mm), automatic rectangular TDF duct lines, TDF flange-forming machines, and a range of duct welders (seam, stitch, spot, elbow, medium-frequency and laser).

Machinery for this application

The duct fabrication workflows above run on standard Taokron equipment: spiral tubeformers for round duct, auto duct production lines for rectangular duct, and TDF flange and lockformer machines for closure — or browse the full machine catalog.
