A mold for use in the production of a ballistic article from a composite laminate stacked material wherein the mold has a sliding sealing section that nests with a outer perimeter section and base portion so as to shield the sides of the composite laminate stacked material from applied isostatic pressure applied when in an autoclave. By shielding the sides of the composite laminate stacked material excess resin matrix material can be forced from the composite laminate stacked material to provide a uniform composite article with reduced weight and reduced thickness.

An apparatus according to the present exemplary embodiment is an apparatus that forms a composition on a substrate using a mold. The apparatus includes a gas supply unit that supplies gas to a periphery of a space sandwiched between the mold and the substrate, a deforming mechanism that deforms the mold, and a control unit that, in a state in which the gas supply unit increases a density of the gas in the periphery of the space sandwiched between the mold and the substrate, after the deforming mechanism deforms the mold in a concave shape with respect to the substrate and releases the mold from the deformation, brings the mold into contact with the composition on the substrate.
