    Why choose this machine?

    One machine replaces 3 fixed-width machines

    This is the biggest advantage of this machine. Instead of buying separate machines for 40mm, 50mm, and 60mm C-channels, you just adjust the width on the touch screen and you’re ready to go. No more changing rollers, no more downtime, no more wasted money on multiple machines.

    Unmatched Production Efficiency & Labor Savings

    Genuine Panasonic PLC for unbeatable reliability

    We don’t use cheap generic PLCs that break down every few months. This machine comes with a genuine Panasonic control system, which is known worldwide for its stability and durability. It runs smoothly day in and day out, and you’ll almost never have to deal with electrical issues.

    High-Grade Materials & Long Service Life

    Compact design that fits anywhere

    Most C-channel machines are 6–8 meters long and take up half your workshop. This one is only 3.5 meters long and weighs just 2 tons. It fits easily in small garages and workshops, and you can even move it around with a forklift if you need to rearrange your space.

    Precise Forming Meeting International Standards

    Dead simple to operate and maintain

    Any regular worker can learn to run this machine in 10 minutes. The touch screen interface is intuitive, and there are no complicated parts to break. Maintenance is just basic lubrication every few weeks, so you don’t need to hire an expensive technician just to keep it running.
