Fully Automatic CZ Purlin Machine One Click Switching Zero Manual Die Change
In traditional C/Z steel production, changing specifications often meant a machine shutdown for over half an hour. You had to loosen bolts, lift molds, recalibrating... Not only does this waste time, but it also demands highly skilled operators. However, our fully-automatic cz purlin machine has completely changed this situation. A simple button press on the touch screen triggers the hydraulic system to switch automatically between C-type and Z-type profiles without any tools.This machine covers a width range of 80mm to 300mm and a thickness range of 1.0mm to 3.0mm. Below, we will provide a detailed explanation of the technical configuration and production value behind this "one-click switch".
Hydraulic Automatic Mold Change System: How Does It Work?
This machine uses a hydraulic station (11kW) as the power core, and the PLC system fully controls it. After you input the parameters such as the width of the target product, the height of the flange, and the thickness of the lip on the touch screen, the system will automatically drive the hydraulic cylinder to adjust the position of the rollers, and simultaneously complete the interlocking switching of the C/Z mode molds. The entire mold change process takes no more than 10 minutes, and requires zero manual intervention. The best part of this system is its adjustable frame design - we install all the formed rollers on the movable frame base,and hydraulic push rods precisely position them. You don't need to prepare multiple sets of backup molds, nor do you need experienced workers to repeatedly adjust. Just input one time, and the machine will handle it all by itself.
What Specifications Can This Machine Produce?
Based on the cold bending forming process, this machine can simultaneously produce C-shaped steel and Z-shaped steel. The applicable range is as follows:
| Product Type | Width | Flange | lip | thickness |
| c purlin | 80-300mm | 30-100mm | 10-20mm | 1.0-3.0mm |
| z purlin | 120-300mm | 30-100mm | 10-20mm | 1.0-3.0mm |
Whether it is the main beams of the light steel villa, the purlins of the industrial factory building, or the load-bearing structure of the photovoltaic support, the above-mentioned size range is sufficient to cover the needs of the vast majority of construction projects.

Unloading system: This hydraulic segmented expansion unloader uses a speed sensor to automatically adjust and match the main machine's speed, preventing stretching or accumulation.
Drilling Station: It features 4 groups (3 for drilling and 1 for pre-forming cutting) and uses Cr12mov quenched molds. The system finishes drilling before forming to ensure precise hole positions with no burrs. Also, the pre-cutting station removes the uneven parts at the head of the steel coil, ensuring stable subsequent forming.
Formed machine: This unit features an H-steel welded base and a cast iron arched frame with chain drive. The total length of the entire line is 22 meters.
Cutting method: The machine performs post-forming cutting using hydraulic power and automatic fixed-length sizing. The length tolerance is 3000mm ± 1.0mm, ensuring that you do not need any additional adjustments during on-site assembly.
Receiving platform: The receiving platform uses an automatic stacking machine to neatly stack the finished products for direct packing.
The Actual Benefits Of One Click Switching
For most factories, frequent model changes cause massive downtime. Assuming an 8-hour working day, three 30-minute changeovers waste 1.5 hours, resulting in a nearly 20% capacity loss. Our one-click hydraulic switch reduces this changeover time to under 10 minutes. This means:
Small batch orders can also be accepted: With drastically lower changeover costs, you can now easily handle small orders of just a few hundred meters, significantly expanding your business scope.
The labor intensity of workers has significantly decreased: Operators no longer need to carry heavy molds or repeatedly test and adjust. An ordinary operator can take over after just half a day of training, eliminating the reliance on scarce senior workers.
Higher equipment utilization: Producing more finished products annually directly translates into substantial additional profits.
Additionally, the PLC program storage function enables you to import production specifications via USB.. Simply click to retrieve them next time without re-entering parameters, saving at least 15 minutes of setup daily for factories with frequent order switches.
