Overview
For mixed box-and-pan and straight-profile work, judge the Erbend MFD by the hardest part’s bend sequence, not capacity alone. Its rotating combi clamping beam changes clamping-tool geometry without a physical upper-tool change; clearance and finished-part removal still need checking.
- The beam rotates 180 degrees between a 100 mm-high segmented goat-foot tool and a single-piece sharp-nose tool set at 20 degrees. Tool height alone does not establish finished-pan depth.
- Working lengths are 2,550 mm for the 2525, 3,200 mm for the 3220 and 4,200 mm for the 4215. Compare actual stock and blank length with the specific model; capacities vary by model and material.
- A 1,000 mm servo backgauge and ERFOLD BASIC line-by-line CNC control are standard. Longer backgauge arrangements and ERFOLD ADVANCED 2D/3D graphical control are optional. Check gauging, blank support and programming needs.
- Bring drawings or flat patterns, material grade, actual thickness, finish, blank dimensions, flange heights, corner details and the intended bend sequence. A forming trial can help check clearance, finished dimensions, surface condition and part removal.
The Erbend MFD can suit a mix of box-and-pan and straight-profile work when the hardest representative part clears the tooling and bend sequence; its rotating combi clamping beam offers two tool stations without a physical upper-tool change.
Two clamping-tool geometries on one beam
A folder clamps the sheet between beams and uses a folding beam to form the bend. On the MFD, the clamping beam rotates 180 degrees between a 100 mm-high segmented goat-foot tool and a single-piece sharp-nose tool set at 20 degrees. The operator can select between those clamping-tool geometries by rotating the beam rather than removing one upper tool and installing another.
That arrangement is relevant when a shop runs cut-sheet pans, covers, or enclosure panels alongside straight profiles. Roof accessories, facade cladding, and HVAC sheet metal are among the application families to consider. The two stations do not remove the need to position blanks, set up jobs, or handle parts, and their availability does not establish that every part geometry will fit.
Let the difficult part determine fit
A previously formed side, tall return, or deep pan can interfere with a beam or tool during a later bend. Corner reliefs, support for the blank, the order of bends, and the path for removing the finished part also affect whether the sequence is workable. Tool height alone does not establish a finished-pan depth for every design.
Assess the hardest representative blank through its intended bend sequence. The useful application details are the flat pattern or drawing, material grade and actual thickness, finish, blank dimensions, flange heights, and corner details. A forming trial can help check clearance, sequence, finished dimensions, surface condition, and part removal before a shop treats published capacity as proof of fit.
Match length, gauging, and control to the mix
The MFD family lists working lengths of 2,550 mm for the 2525, 3,200 mm for the 3220, and 4,200 mm for the 4215. Published capacities differ by model and material, so compare the actual stock and blank length with the specific machine under consideration rather than treating the family as one rating.
The standard configuration includes a 1,000 mm servo backgauge and ERFOLD BASIC line-by-line CNC control. Longer backgauge arrangements and ERFOLD ADVANCED 2D/3D graphical control are optional. Confirm that the gauging and support arrangement suit the actual blank and part, and check the control configuration if graphical programming is required. Folders can be a fit for light-gauge, painted, or surface-sensitive architectural sheet, but the result on a particular material and finish still needs to be assessed on the part.
I’m Patrick O’Neill, Mac-Tech’s National Product Manager / Regional Sales Executive for the U.S. market. I can help assess whether the MFD’s model length, tooling stations, backgauge, and control configuration suit your part mix, and whether a forming trial is warranted. Bring drawings or flat patterns for your most demanding pan and profile, along with material grade, actual thickness, finish, blank dimensions, and the intended bend sequence.
