How about the gigantic pipes you saw on the side of the road while you were driving to work? These are just a couple interesting examples for what can be done with plate rolling technologies and plate rolling machines today. ## What is Plate Rolling? Plate rolling is a fabricating process that is used to form various types of sheet metal, mainly stainless, aluminum and steel into circular, conical, round or any other shapes. Plate rolling machines (aka “plate rollers” or “roll bending machines”) give materials their shape by using force through their rollers that are powered by mechanical, hydraulic or electrical systems. A plate rolling machine selection is made based on the rolling capacity needed. In recent article titled Your Guide to Determining the Plate Rolling Capacity of Your Plate Roll more details can be found on plate rolling capacity. ## What is Pre-Bending in Plate Rolling? Pre-bending refers to the process of holding sheet metal firmly between multiple rolls and pushing it in order to create the initial bend. With the rotation of the rolls on the plate rolling machine, the material is fed through the rolls and once the 360 degree rolling process is completed, the pre-bent end of the material makes it very easy to connect the 2 ends, thanks to the pre-bending process. ## 4 Reasons Pre-Bending is Crucial When Selecting a Plate Roll - ### Eliminates Waste Pre-bending process helps minimize waste by creating an optimum geometrical formation so that both ends of the material can get in touch after rolling as perfectly as possible. Practicing pre-bending process while having an experience and skilled plate rolling machine operator play a very critical role in eliminating waste. - ### Eliminates the Need for Extra Trimming The resources used on extra material trimming in plate rolling is nothing to be ignored for any efficiently and effectively functioning fabrication shops or operations. The need for extra trimming can easily be avoided through pre-bending by forming an optimum alignment of both ends of a sheet metal after rolling the material. - ### Saves Time Especially for high-volume production shops, wasting a minute out of the production time means wasting money and it can add up real fast over time. Since pre-bending helps an operator to form the desired shapes faster, the operating time per sheet metal on a plate rolling machine diminishes, which means rolling more parts with less time. - ### Smooth Bending Surface and Uniform Curvature / Thickness Pre-bending process is one of the most important practices in plate rolling when it comes to being able to get the results that was initially intended to get, which is simply rolling the material correctly. Properly rolled material will inevitably result in smooth material surface and uniformity in material curvature and thickness. ## Shop Bendmak Plate Roll Systems At BendmakUSA we offer a wide range of Plate Rolling Machines for every shop’s budget and needs.
