A combination padlock with a name card has a housing, a card clamp, multiple dial cores, a shackle, a locking shaft and a key core. In this method, after piercing in the piercing rolling process, rolling is performed without using an inside regulating tool in the elongation rolling process, or without performing the elongation rolling followed by reducing rolling in a reducing rolling process, and thickening is then performed by use of a cold mill or cold draw bench in a cold rolling process. These MSI shapes are oriented in a plane perpendicular to the air-bearing surface. The main body has an external housing, charging plugs and an plug storage device.
