Panel forming machine: things to consider before buying

When buying a stationary plate roll forming machine, one of the first factors to consider is whether to buy a single, double or multiple contour machine.
What are the options? The single-profile roll forming machine has only one set of frame, shaft and roll mold. If you want to roll forming from a specific profile, this is a good choice. Depending on the profile, you can choose between cutting the front line or cutting the post line. Entry-level machines are relatively inexpensive, and the production speed is about 100-150 FPM. Companies with high-volume requirements usually use single-profile equipment and use fly-stop systems to reach speeds of 400 FPM.
Advantages: Affordable entry-level machines are suitable for start-ups that don’t need the best speed, while higher-priced production lines in similar products provide high-volume companies with excellent production speeds. Disadvantages: Only one panel profile can be processed.
Double-contour machines are often called double-height machines or double-layer machines because there are fewer racks and tools for one contour, and higher racks and tools for the second contour. Both levels are based on a common foundation. Materials enter and exit from the upper or lower layer. If floor space is limited, adding a second layer to the existing roll forming machine is a good choice.
Running two configuration files on just one machine can also save manpower and save additional costs for the second set of auxiliary items (electrical settings, controllers, uncoilers, shears, etc.) required for the new production line. When saving space, only one level can be operated at a time. The following are the most common profiles on the dual profile panel row: • “Ag” panel • R/PBR panel • U/PBU panel
Advantages: Enable the owner to provide two styles of panels; Disadvantages: Only one configuration file can be run at any given time.
Multiple profile machines (also called sub-plate or drifting machines) can be produced on the same layer, and the cost is higher. These production lines are usually used by large manufacturers who have requirements for many different contours. Not all markets have this kind of demand, but there are exceptions. Each profile has its own set of brackets and tools, mounted on interchangeable “daughter boards” (also known as after or bullets). The conversion is relatively fast, but an overhead crane or forklift is required to switch the bottom plate/r sub/cartridge.
Advantages: It can meet the needs of an unlimited number of panel configuration files, thereby eliminating the need for multiple machines. Disadvantages: The cost is usually higher compared to single profile or dual profile. Overhead rigging (forklift or crane) is required for conversion.
What is your current potential market? Experts generally agree that potential buyers should understand the market before buying any machine. Today, the typical regional rolling mill market requires ag panels or R/PBR panels, but maybe neither, or more.
How did you know? Ask about the roof and/or lumberyard you plan to manufacture. The market has a strong demand for regional panel favorites (styles and specifications), which can be changed, but usually do not change frequently or significantly. Roofers tend to stay on the panels they are most familiar with and comfortable to use. This can be determined by whether their market is mainly residential, commercial, agricultural or a combination of the two.
