TDC/TDF Machines

FORMTEK / LOCKFORMER / ENGEL

Q. Why do HVAC Contractors buy TDC/TDF flanging machines?

A. Really, the answer is quite simple; these machines roll the 35mm standard flange onto existing duct in about 6 seconds per length.

The alternative method is to buy expensive knock on flange, approximately $2.75 per metre in 5 metre lengths so when you are trying to manufacture a piece of duct you take the flange off the shelf, cut 4 pieces, deburr it, fit it with expensive corners, place on the end of the raw edge, and either tech screw or spot weld and seal.

With TDC/TDF you simply notch your sheet, roll of the flange, bend up the duct and clip in 4 corners at $1.20 all up.

The TDC/TDF method will save you approx. $40 per joint. Eliminates the necessity to stock knock on flange, it saves your cash flow as well as labour savings.

The TDC/TDF method is really a no brainer. Any serious Duct Manufacturer cannot afford to not use either TDC or TDF.

Use the TDC/TDF method with a beading machine for strengthening ribs in lieu of time consuming cross braking for a better looking piece of duct.

Fold the duct in L Shape, C Shape, or Wrap utilising the Kleen TDC/TDF Wrap Brake. You’ll be amazed at the savings your business can make piece of duct.

LOCKFORMER TDC™ ROLL FORMING SYSTEMS

Instead of add-on flange, roll forming your own sealable flanges on transverse duct joints during the fabrication process has never been easier. The TDC flange, per SMACNA Duct Construction Standard (DCST25a) specifications, is formed on the machine’s left-hand auxiliary, has unique, snap-in corners that eliminate spot welding. Optional rolls are also available for Z-Bar and TDC Clip.
