Abstract

PURPOSE:To facilitate each process in a similar method without skillfullness by spraying or coating the external surface of a mold in a shape, which corresponds to the internal surface of a required horn, with the releasing agent, by melt-spraying it with a metal, or by applying a glass-fiber reinforced plastics. CONSTITUTION:On the surface of mold 1 made of glass-fiber reinforced plastics FRP, etc., and having the external surface in a shape that corresponds to that of the internal surface of a required horn, this layer 2 is formed of polyvinyl alcohol by spraying or coating. On it, metal coating 3 of adequate thickness is further formed of Al, etc., by meet-spraying and on the coating, layer 4 of plastics FRP is formed by pressure injection; after layer 4 is hardened, mold 1 is removed to manufacture the required horn in the internal surface shape. Consequently, each process can be facilitated in a similar method without skillfulness.
