Pyrotechnic Target and Method of Manufacture

摘要

An impact initiated pyrotechnic target is shown in the form of a thin metal disc. The disc is manufactured using a shell casing in the form of a metal disk having a flat, round exposed disc surface and a circumscribing cylindrical lip. The lip extends upwardly past the exposed disc surface and is turned in on a radius. The exposed surface of the disk inside the periphery of the cylindrical lip is coated with a pyrotechnic composition coating layer which can be initiated by the impact of an inert projectile. A cardboard lid is snapped into place over the exposed disc surface and is held in place by the turned-in periphery of the cylindrical lip of the disc.

1. A method of manufacturing an impact initiated pyrotechnic target in the form of a shell casing made from a thin metal disc, the method comprising the steps of:
providing a thin metal disc, the disc having a flat, round exposed disc surface and a peripherally circumscribing cylindrical lip, the lip extending upwardly past the exposed disc surface a predetermined height; the disc lip also being turned-over and turned-in upon itself on a given radius; wherein the exposed surface of the disk inside the periphery of the cylindrical lip has applied thereto a pyrotechnic composition coating layer which can be initiated by the impact of an inert projectile; and wherein a circular protective lid is snapped into place over the exposed disc surface and is held in place by the turned over and turned-in periphery of the cylindrical lip of the disc to thereby form a completed shell casing.
