Customizable Pneumatic Lock Seam Closing Equipment for Galvanized Steel Duct Production

When people first see it, they usually ask about air supply—yes, it runs on compressed air at 0.6 to 0.8 MPa, and you'll need a pump that, nothing exotic. We've shipped these to plenty of sheet metal shops, and most buyers go with the standard 1100-1300 mm duct length range, though we can adjust that if your runs are weird. Teh 650 kg weight means you'll want a forklift or at least a pallet jack for positioning, but once it's set, it's pretty stable.

And the max sheet thickness is 1.0 mm, which is fine for residential and light commercial work, but honestly, it's not ideal for heavy-gauge industrial ducting over that, so keep your material spec in check. That's a thing some new buyers overlook—it handles galvanized and steel sheet fine, but if you're pushing 1.2 mm, it jams. We usually do COA and CE certification with each unit, and if you need an HPLC purity report or whatever, our company can provide that, though it's more relevant for our chemicla lines.

We've got options on color and some control panel tweaks, so customization is actually real here, not just a checkbox. The semi-automatic operation is straightforward—load the workpiece, foot-pedal or button start, and it locks the seam without much fuss. I'd say production capacity is roughly 50-60 pieces per hour, give or take, depending on operator speed. Payment is typically 30% deposit and 70% before shipment, but we're flexible on T/T or L/C for established accounts.

14 days lead time on standdard units, but if you want custom duct length ranges or a different color for your shop, add another week or so. We do offer overseas engineer support, but for most setups, the manual and a quick video call cover it—unless you're running 24/7, it's overkill. The floor footprint of about 3 meters by 0.88 meters is narrow enough to tuck against a wall. Warranty is one year, and we stock common spare parts like seal rings and valves for routine wear.

Basically, this is a workhorse for shops doing repetitive rectangular ductwork, and the pneumatic design keeps maintenance low compared to hydraulic or electric alternatives. But if you're doing crazy high volumes or top-secret specs, you might want the full automatic line—that's a different budget though. The 3060×880×1000 mm dimnesions fit standard shipping containers without special crating, and we can arrange door-to-door freight if you want.
