A system and a method for two-shot molding a crash pad, in which a passenger side air bag (PAB) door region is more flexible than other regions is disclosed. The system includes a first resin supply unit, a second resin supply unit, a temperature sensor mounted on a predetermined position of a mold, adjacent to a target material interface, and a controller for controlling a time at which to supply the second resin into the passenger side air bag region based on a detection signal from the temperature sensor. This system is cost effective and can maintain a uniform interface between different types of materials.
