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 multi-contour machine.
What are the options? The single-profile roll forming machine has only one set of frame, shaft and roller molds. 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 cheaper, and the production speed is about 100-150 FPM. Companies with high demand usually use a single contour machine with a fly-stop system that can reach 400 FPM.
Advantages: Affordable entry-level machines can be used for start-ups that do not require the best speed, while higher-priced production lines in similar products can provide high-volume companies with excellent production speeds. Disadvantage: Only one panel profile can be processed.
Double contour machines are often called double-height machines or double-layer machines because the number of racks and tools used for one contour is small, while the number of racks and tools used for the second contour is higher. 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 relatively high. These production lines are usually used by large manufacturers who have requirements for many different profiles. This demand does not exist in all markets, 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 an unlimited number of panel configuration file requirements, thereby eliminating the need for multiple machines. Disadvantages: usually more expensive than single or dual configuration files. Overhead rigging (forklift or crane) is required for conversion.
What is your current potential market? Experts generally agree that potential buyers should understand their market before buying any machine. Nowadays, the typical regional rolling mill market requires ag panels or R/PBR panels, but maybe neither, or more, or both.
How did you know? Ask about the roof and/or lumberyard you plan to build. The market has great demand for regional panel favorites (styles and specifications), which can be changed, but usually do not change frequently or by a large margin. Roofers tend to stay on the panels they are most familiar with and most comfortable to use. This can be determined by whether their market is mainly residential, commercial, agricultural or a combination of the two.
