A method for manufacturing a crash pad for a vehicle, may include (a) preparing a die including an upper die and a lower die for forming a first cavity for a Passenger Air Bag (PAB) door and a second cavity for a crash pad body, between the upper die and the lower die, (b) fixing a skin foam on an upper surface of the lower die, (c) moving the upper die in an upward direction in a predetermined distance and filling the first cavity for the PAB door with a first material and the second cavity for the crash pad body with a second material, (d) moving the upper die in a downward direction to compress the first and second materials against the lower die, while the first and second cavities may be filled with the first material and the second material, and (e) extracting a core of the PAB door and the crash pad body integrally formed with the skin foam from the die.
