Sheet Metal Forming Machinery

The opening rolls are heat treated when manufactured so that they are not too hard (otherwise they would chip) and not too soft (otherwise they would easily wear out). Without it the pocket closes like this… And the male Pitts doesn’t seat easily… When you know that it’s time to replace the Opening Roll wheel […]

Fastening ductwork like square to rounds and flex connections into an assembled fitting can be done with Drill Screws, Pop Rivets, an Acme Lock, a Spotwelder…or a Clinching Machine.  While a spotweld’s burn marks don’t make for an aesthetically pleasing product, the products made in a duct shop typically don’t require it. One reality many shops are facing

The Trumpf F301 Seamcloser is an alternative to an Air Hammer in closing the Pittsburgh Seam into a Lock by means of rollforming it over instead of hammering it over. There are advantages to Closing the Pittsburgh by a Rollforming process rather than a Knocking Over process—a much quieter process and a cleaner looking Lockseam

Because of the name, there’s confusion between these two machines. While each machine turns a flange on the edge of metal, one works only on a flat piece of metal while the other works only on an already formed round pipe edge. Therefore when it comes to their function in a sheet metal shop, these

The common method for “turning the drive” is by means of bending the edge of sheet metal “up and over” to form a 7/16″ open hem 180 degrees using either a manual or pneumatic cleatbender. But there’s another option…Rollforming. Shops with a Coil Line are the best candidates for a Drive Turn Rollformer if the Coil Line has

Since Rectangular Duct fabrication revolves around the Longitudinal and Transverse profiles, the “must have” machines are mostly ones that fall into one of those two categories, so here we go… #1. Pittsburgh Machine:  This machine rollforms the female pocket seam and since Pittsburgh is the universally accepted lock in commercial HVAC ductwork, every shop has a standard

The choice of Oval by engineers is driven by ceiling height factors on jobs that would otherwise be round Spiral. By taking Round Spiral and pushing/pulling it into an Oval shape, the engineer can get that same round diameter in an equivalent Oval shape and avoid ceiling height restrictions that the round pipe would encounter. We’re seeing

It’s a common source of confusion and it’s not just because they have similar names. These two machines look similar—two handles, close in size, and mount on a stand. Because each is an essential machine for Rectangular Duct Fabrication, every Sheet Metal shop making duct has one—and from a distance it’s easy to mistake one for

S and Drive Rollformers have a minimum of 8 Forming Stations and roll form the Flat S and Flat Drive. When contractors refer to S and Drive Duct, they are also including the “reinforced” Flat S , aka the Standing S Lock From a fabrication and transport perspective, S and Drive Duct is the most cost

Offering the simplest and most economical method to clinch two (2) pieces of same, dissimilar, or painted metals with 28 to 14 gauge mild steel capacity. Air Cam Model AC-3-26 Free Standing Clinching Machine Demo No Spot Welding and No Rivets Less Expensive Than conventional clinching machines due to low CFM usage (1/3 the competition)

SURELOK II E-25 and E-18 Floor Mounted Clinching Machines SURELOK II P offers greater clinching versatility and is able to fasten material from as thick as 14 gauge to as thin as 32 gauge. Rigid steel frame offers less deflection for longer tool life Close tooling access to get in close for more applications Fast

Vicon Full Wrap Coil Line Fabricates One Piece Duct Fabricates Two Piece Duct Vicon Full Wrap Coil Line Proudly made the in U.S.A. In a typical rectangular duct job, 75% is comprised of straight runs of Duct.  Automating the fabrication of these Duct Sections can take a 2 day process to a 2 hour one.

Pexto forming machines offer a broad variety of shapes and capabilities in forming sheet metal for a combination of uses: beading, crimping, setting down, double seaming, turning, burring, wiring, elbow edging, flanging, and flattening.         Most are portable and may be set up at the job with a clamp-on base. These machines

Namcor Strikermatic How is your shop making square to round transitions?   The Strikermatic is Powered by a 20 volt Dewalt rechargeable battery (included). The battery charge should last several days but definitely good for a single day no matter the usage. The machines electric cycles allow the user to have some control over the

Cleatbender (aka Drive Turn Machine) Slip and Drive duct with Pittsburgh Lock Turning drives on a manual cleatbender is a close second behind the Pittsburgh air hammers for the least popular task in a duct shop because it requires three awkward handle pulls to complete the profile and it’s a profile that the shop is

24 gauge Pittsburgh Machine Avoiding the Wavy Hammer over edge of a Pittsburgh by using a Model that’s closer to the gauge being used Have you ever looked at the Pittsburgh Seam and notice that the Hammer Over Edge seemed a bit wavy? I have but really didn’t think too much of it although I’ve

Vicon 520-DL Dual Plasma and Liner Cutting System: Taking automation of the Fittings to another level… One of the most manual tasks in Duct Shops is the process of laying out, measuring and manually cutting liner fittings to their corresponding metal fitting. Liner Drop accumulates daily in each shop due to measuring mistakes and poor cut

Automating Fabrication of Straight Duct There are two operations that even a Full Wrap Coil Line with every bell and whistle cannot complete: The Seaming of the Pittsburgh Lock and the insertion of the 8 Corners Three machines will automate the part of the job that accounts of 75% of the Duct on a typical
