PURPOSE:To facilitate the die release of a FRM and yet to prevent the flaw on the surface of the FRM by interposing the metal foil having higher m.p. than that of the metal becoming the matrix of a fiber reinforced metal composite material (FRM) between an aggregate and die prior to pouring of a molten metal into the die. CONSTITUTION:The metal foil 8 of higher m.p. than that of the metal attaining to a matrix is inputted into the cavity 4 of an inner die 5 after multiple-winding it on a fiber reinforced aggregate 7. The molten metal 9 of the metal becoming a matrix is pouring into the cavity 4 in this state and impregnated to the aggregate by pressing it by a plunger 10. After the molten metal being solidified the inner die 5 is taken out of an external die 3 by pushing the inner die 5 up by a knockout pin 6 and split by lightly striking it by a hammer, etc., to take off the FRM together with the foil 8. With the metal foil 8 of this case no seizure is caused on the molten metal and die, the die release of the obtd. FRM is facilitated and the separation of the metal foil and FRM is easy, so the surface of FRM is not damaged.
