Apparatus and method for manufacturing crash pad

An apparatus and method for manufacturing a crash pad with a foaming layer formed by injecting a foaming solution between a core and a skin are disclosed. The apparatus includes a first mold and a second mold used to form the skin by injecting molten resin of a skin material into a skin forming cavity when the first and second molds are combined. In addition, a third mold and the fourth mold form the core by injecting molten resin of a core material into a core forming cavity when the third and fourth molds are combined. The first mold has a vacuum aperture in an inner surface of the first mold to adsorb and fix a thread to implement a stitch before the forming of the skin, and the vacuum aperture exerts a vacuum suctioning force to absorb and fix via a vacuum pressure applied from a vacuum pressure providing unit.
