By continuously moving the slot in sync with the cutting head, the system is always cutting over open air, while the entire coil of material remains supported. Without slats and the risk of the laser colliding with them, the system prevents flashback. As an added benefit, the slot has the ability to open and close. This feature allows for parts to be separated from slugs and smaller pieces of scrap, which are removed in a side out process. This helps streamline scrap removal.
Besides no scratching of parts, what are the other benefits?
Another key advantage is the ability to avoid tip ups. When laser cutting parts supported by laser cutting slats, it is critical that the part is supported in various points. As the part is cut from the sheet, part could tip depending on points of support. This can cause a major jam if the laser head were to run into it. It can also disrupt the finished part handling process. Part tip up is not an issue since the parts are supported by a conveyor belt instead of slats.
Improved exit part handling and automation is a great benefit. The finished parts after cutting exit onto a handling conveyor outside the laser enclosure. A drop stacker, robotic stacker or other downstream process will handle the parts from the conveyor. With no flashback, the parts will be loose from other parts, allowing easier downstream handling.
Flashback can cause major issues in your sheet metal processing work. Laser cutting slats enables flashback opportunities. The RDI Coil-Fed Laser blanking technology can effectively laser cut your parts while eliminating flashback. Part and scrap separation will be streamlined, and moves into finished part handling.
