Sheet Metal Forming：Processes, Work, Uses

Product Details: Sheet metal forming involves various techniques to shape metal sheets into desired forms. Key methods include bending, deep drawing, and stretch forming. Bending deforms metal around a straight line, producing bends up to 90° or angles from 30° to 179°. Deep drawing uses a punch to force sheet metal into a die cavity, ideal for making cans, cups, and car body panels. Stretch forming bends and stretches sheet metal over a die, commonly used in aerospace for intricate shapes. The process includes blank preparation, lubrication, positioning and clamping, the forming operation, and part removal and inspection[1].
