Round Duct Making Machines

This mould type tubeformer is designed to automatically form spiral duct for HVAC round duct production. It is an advanced spiral duct forming line with much more reliable performance due to its fixed mould design. Each mould will form spiral tube of one fixed diameter. Compared with band type spiral tubeformer, this machine is of higher durability and the spiral tubes formed are of better air tightness.

The Preda Band Type Spiral Tubeformer with Plasma Cut is an advanced spiral duct production machine that combines the efficient band-type locking system with an integrated 120 Amp plasma cutting system and servo-controlled rail guide. Unlike mould-type tubeformers that require a separate lock strip, the band type system forms the lock seam directly from the strip edges, simplifying the production process and reducing material costs.
