PURPOSE: To provide an apparatus for manufacturing parts capable of forming a hollow part only at a specific position of a part used in a chamber. CONSTITUTION: After injecting resin 5 into a specific shaped molding space S formed by inserting a part of a moving mold 3A into a depression 2a of a fixed mold 2, a part having a hollow part 6 is formed at a specific position by injecting high pressure inert gas. Besides, by providing a projected part 3a in the moving mold 3A, a groove thining a thickness of a connection part 6a between the hollow part 6 of the part and its other part is formed. |
