Flexibly-reconfigurable roll forming (FRRF) is a novel sheet metal forming technology by which sheet metal is shaped into a desired curvature using reconfigurable rollers and gaps. FRRF is conducive to producing multi-curvature surfaces by controlling the longitudinal strain distribution. However. it is difficult to predict the forming results since FRRF technology forms a secondary s... https://fitnessgravesyardes.shop/product-category/control-panel-w-keypad/
