Summary
The AK04F continuously adjustable rectangular-spot edge-sealing head was originally born on a
Laser Marking Machine frame: the same scan optics, the same fiber interface, the same real-time feedback loop. By swapping the Q-switch for a high-duty kW modulator and widening the spot from 20 μm to 8 mm, we turned a precision
Marking Machine sub-assembly into a seam-sealing powerhouse that closes battery-pouch edges at 120 m min?1 without undercut or porosity. So whether you are scaling up from a laboratory
Pneumatic marking machine or down from a heavy-duty
Dot Peen Marking Machine line, the AK04F drops straight onto your 19-inch rack and inherits all the motion libraries you already use for
Laser Engraving—no new software, no new training.
?
From the 20 W MOPA core that signs medical plastics in a Laser Marking Machine, to the 2 kW rectangle-spot head that hermetically seals EV cells, to the
Consumables that keep your Dot Peen Marking Machine pins and Pneumatic marking machine chisels running 24/7, we deliver one total industrial-laser ecosystem. One controller, one cable set, one process database—covering everything from micro-UDI codes to full-width edge sealing—lets you migrate seamlessly between Marking Machine, cleaning, welding and sealing without ever changing platforms.
