Buying lots of preformed HVAC duct gets very expensive, but you can form your own with machines and tools for forming sheet metal into shapes for Heating, Ventilating, and Air Conditioning duct work. Cutting can be done using hand shears, a rotary slitter or sheet metal shear. 90 degree bends can be formed on "easy edger" right angle flanger or a sheet metal hand brake. A few other simple shapes can be bent using a bar folder, cleat or cheek bender but these methods are slow. More complex shapes and longer lengths are best formed on a HVAC roll forming machine also known as a lockformer machine. Pittsburgh lock, Drive Cleat, and ACME Double Seam are made on a machine with at least 5 sets of roller dies. Button Snap Lock and S clip need 9 sets of roller dies. If you need to feed lots of metal to a rollformer consider using an uncoiler. To form elbows use a manual or powered right angle flanger and slip rolls. Take careful note of the minimum and maximum allowed metal thickness and also the electrical requirements of any machine you are considering. The S & Drive Former, Button Snap Lock or Fourplex Cleat Former machines are normally 220 volts, 3 phase with optional 1 phase 220 volts costing extra. Some less expensive machines are designed for use in small shops, others may cost more but are for frequent heavy use. Click for our budget priced TIN KNOCKER HVAC MACHINES
