In simple terms: one mold, two injections, one cycle. The first plastic injection runs through the mold and then gates are closed, the mold is automatically rotated (rotary mold), or a part is transferred within the same mold (pick and place) and a different type of plastic is injected into the mold.

A two-shot mold offers different resins in the same part and same mold. Those different resins in a second shot could be for:

Appearance (i.e. clear windows, gloss finish)
Strength (i.e. gas filled)
Feel (i.e. non-slip grip)
Multi-color
Function (i.e. rubber seals, gaskets).
