A punching machine triggers the punching process by inputting the material. Therefore, in addition to normal punches, a punching machine requires an insertion and release system. The type of insertion system can vary. For punching machines that stand alone, the raw material is often in strip form and placed in front of the machine. It is then continuously fed into the punch by a guide rail and stepping motor.

The use of raw material in strips has the advantage that excess material can be rolled up again, just like the raw material for the punching process was rolled up. This ensures efficient levels of recycling.
There are a large variety of further inputting systems, including the use of a robot arm, which is relatively complex. This is particularly useful for large, heavy and bulky material and punched products. For the undertaking of the punching process, there are a large variety of technologies available. The release mechanisms that are most used are simple pressure switches or light barriers.
