The invention concerns a method for forming metal parts by cold deformation, consisting in: mechanically depositing a metal zinc layer on the free surface of the blank of the part to be produced; and forming said part by plastic deformation. Such a garment hanger has a body, a hook member connected to the body, a tab holder operatively connected to said hanger. The row selection time is subdivided in npwm sub selection time. A rail extends from the main body. Objects in view may be tracked and blanked by obscuring an agglomeration of the cells in response to a masking signal generated by the microcontroller.
