Some of the available edge material is placed in the designated area to provide the material for the die test during bending. After the workpiece blanking edges, burrs, contact to make the necessary modification (polishing process), the cutter contact, with a flat file for shaping, about burr larger finishing workpiece with grinding machine, small hole contact with corresponding small file modification, in order to ensure that the appearance of beautiful, appearance of finishing together also made to ensure to bend when positioning, When bending, the workpiece depends on the bending machine in the same direction, to ensure the same batch of product size.

Sheet metal processing process you know how much in the blanking completion, into the next process, different workpiece according to the processing requirements into the corresponding process. There are bending, pressure riveting, flanging tapping, spot welding, punch hull, section difference, sometimes after bending one or two to the nut or stud pressure, which has a mold punch hull and section difference to consider the first processing, to avoid other processes after the first processing will interfere, can not complete the needed processing. When there is a hook on the upper cover or the lower shell, if it cannot be touched after bending, it should be processed before bending.
