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.

A co-injection molding apparatus may mold an injection product that includes a skin layer forming an outer surface by a first material and a core layer surrounded by the skin layer and having an interior formed by a second material. The co-injection molding apparatus may include an injection mold configured to form an injection space to be injection molded by the first material and the second material, a first injector configured to inject the first material, a second injector configured to inject the second material different from the first material and positioned between the first injector and the injection mold, and a runner configured to connect the first injector, the second injector, and the injection mold.
