Ultrasonic V-Cut Webbing Cutting Machine with Shaped Press Die, 15 kHz WM-581

›

The WM-581 is a press-type ultrasonic cutter: webbing is laid into a shaped die on the work table and one 85 mm cylinder stroke drives a 15 kHz horn down to cut and seal the V profile in a single hit. The shape is machined into the tooling rather than set on a blade, so thick flat braided rope and strapping come out with identical V ends every stroke, fused closed against fraying. The 2,600 W generator runs on 200–240 V AC with automatic real-time frequency tracking, welding amplitude adjustable from 10% to 100%, a Chinese/English interface and a stroke counter. The floor frame measures 650 × 750 × 1500 mm and weighs 160 kg.

Specifications

Key features

• The V profile lives in hardened tooling, not in a blade setting — shape, depth and symmetry repeat identically on every stroke, and a new end shape is a die change rather than a machine change
• 15 kHz horn at 2,600 W cuts and fuses in the same instant, so dense flat braid comes off the die with closed, fray-free V ends and no separate singeing step
• 85 mm cylinder stroke clears bulky material into and out of the die, and the two START buttons sit at opposite ends of the panel so the stroke fires with both hands away from the tooling
• Welding amplitude is adjustable from 10% to 100% with automatic real-time frequency tracking — heavy braid and light tape are handled by dialling amplitude, not by re-tooling
• Generator protects itself with die impedance analysis, voltage, overload and transducer protection, cross-checks time against energy on every cycle, counts strokes and reports over 485
• Free sample test — send your webbing, we cut it on this machine and send you the video and the cut pieces before you order

What it processes

• V-notched and shaped ends on flat braided rope, webbing and heavy strapping
• Thick or multi-layer braid that a reel-fed inline cutter cannot pull through cleanly
• Short runs and mixed shapes where the profile changes with the die instead of a program
• Sealed shaped ends for slings, pull tabs, handles and harness straps that must not unravel

Suited for: V-shaped and other die-formed ends on synthetic webbing, strapping and flat braided rope — especially thick or dense braid where the end must be fused shut and the profile has to come out the same on every piece. Not suited for: continuous cut-to-length production from a reel. For sealed straight, beveled and arrow-point ends fed off the roll at 60–80 pieces per minute, pick the WM-567 ultrasonic ribbon and tape cutting machine; for programmed lengths from 1 to 10,000 mm on rope, ribbon and webbing 1–80 mm wide and 0.1–8 mm thick, pick the WM-574 ultrasonic rope and webbing cutting machine. Hole patterns belong on the WM-564 ultrasonic webbing punching and cutting machine.

Send us a metre of your webbing with a sketch of the end shape and we cut it on this machine on camera, then mail the pieces back — you inspect the fused V ends on your own material before anything is ordered.
