Guiding

Each machine within the production line must be meticulously positioned to maintain the steel coil consistently along a central line, ensuring that the rolling shutter slats remain free from distortion. Therefore, the simple guiding part plays a pivotal role. Multiple guiding rollers are strategically set throughout the production line to fulfill this critical function.

Roll former

Prior to the forming process, a cooling system is implemented to help reduce the temperature of rollers, while also protecting the surface of the steel coil. The machine's cast-iron structure is a complete piece of steel, ensuring stability throughout the forming process and an extended lifespan. The forming rollers are driven by gears, efficiently transferring power from the motor to the rollers. Additionally, we have equipped a protective cover on the gears to ensure the safety of both workers and the machines.

It should be noted that the size, shape, and placement angle of the forming roller will affect the forming point of the profile, so a rolling shutter slat profile requires a roll forming machine. But in order to optimize the solution, we have also launched a double-row roll forming machine, which can save costs.

Flying cut

We utilize a Yaskawa motor to drive the movement of the cutting base, ensuring non-stop cutting at a production speed of 15m/min. Inside the roll forming machine, an encoder records the advancing distance of the steel coil, enabling machines to precisely control cutting lengths within an error of ±0.5mm.

This accuracy is maintained through the PLC control cabinet, where inputting the desired cutting length on the screen leads to precise and efficient cutting operations.
