"We've been running the PD1600 spiral tubeformer in our Düsseldorf facility for over two years now. The consistency of the spiral seam is outstanding — our leak test rejection rate dropped from 8% to under 1%. The PLC control is intuitive, and when we had a minor sensor issue last quarter, Preda's team shipped a replacement part free of charge within 48 hours. This is what real after-sales support looks like."
"We compared three brands before choosing Preda. The PD1600 has been a workhorse — 12 meters per minute, day in and day out. What really sold us was the Preda Care service: their engineer remotely connected to our PLC and resolved a programming question in under 20 minutes. No waiting, no expensive service calls. Our ROI was under 8 months. Highly recommended."

See what our customers say about their Preda Spiral Tube Forming Machine PD1602
The spiral seam consistency on this machine is the best we've ever seen. Our leak test rejection rate dropped from 7% to under 1.5% within the first month. The fixed mould design means every duct comes out perfectly round, batch after batch. Setup takes less than 10 minutes for a diameter change, and the PLC remembers all our common settings.
We went from 4 operators manually forming spiral duct to 1 operator running this machine at 12 meters per minute. Our daily output tripled, and labor costs dropped significantly. The cutting system is clean and precise — no deburring needed. Preda's remote support helped us optimize the feed speed within 20 minutes of installation.
Still Losing Money to Inconsistent Spiral Duct Quality?
Every HVAC duct shop faces the same bottleneck: manual spiral duct forming. When your team spends hours on hand-forming seams and cutting lengths, your production capacity drops, labor costs rise, and deadlines slip. The Spiral Tube Forming Machine PD1602 is engineered to eliminate these inefficiencies — automating spiral tubeformer while delivering consistent, factory-grade quality.
In this guide, we break down exactly how this machine transforms your fixed mould spiral duct machine workflow, what specifications matter for your operation, and how to calculate your return on investment. Whether you run a 3-person job shop or a 50-employee production facility, understanding these details directly impacts your bottom line.
How It Transforms Your Production Line
The Spiral Tube Forming Machine PD1602 operates on a proven principle: spiral tubeformer should be a continuous, automated process — not a series of manual interventions. Here is the step-by-step workflow that makes this possible:
Coil Feeding & Leveling
Galvanized steel or aluminum coil is automatically fed through precision leveling rollers, eliminating coil memory and ensuring a perfectly flat strip enters the forming head.
Continuous Spiral Forming
The strip is wrapped around the forming mandrel while the lock seam is simultaneously rolled and crimped. This creates the characteristic spiral seam that gives round ducts their superior strength and airtightness.
Precision Length Cutting
A flying shear or slitter cuts the continuous tube to your exact programmed length without stopping production — critical for maintaining high output rates.
Automatic Discharge
Finished ducts are automatically ejected onto the collection table, ready for flange installation or direct shipment.

Problems Solved: Before vs. After
We asked 50+ HVAC fabricators about their biggest production headaches. Here is how this machine directly addresses each one:
| Without This Machine | With This Machine |
|---|---|
|
✕ Inconsistent duct diameter
Ducts don't fit together on site, causing rework and delays |
✓ PLC-controlled diameter accuracy ±0.5mm
Every duct fits perfectly on first try, zero rework |
|
✕ Slow manual production
2-3 workers needed per machine, max 5-8 ducts/hour |
✓ Automated continuous production up to 38 m/min
One operator produces 30-60 ducts/hour |
|
✕ Air leakage at seams
Energy loss, failed pressure tests, customer complaints |
✓ Precision spiral lock seam with 360° crimping
Leakage class C/D compliance, passes every pressure test |
|
✕ Material waste from bad cuts
10-15% scrap rate from manual cutting errors |
✓ CNC flying shear with ±1mm length accuracy
Scrap rate below 2%, significant material savings |
Where It Fits in Your Factory
This machine is versatile enough to serve multiple production scenarios. Here are the most common configurations our customers use:
