Abstract
There is provided a mold apparatus and process whereby a warhead body can be fabricated in a single over molding process which may also include therein metal fragments, metal balls, obturators, boat tails and other aerodynamic features, metal rings and/or threads. Other molds and processes are presented whereby a warhead body may be over molded in a polymer matrix in sequential steps which may include adding therein metal balls, then fragments, and any of obturators, boat tails and other aerodynamic features, metal rings and/or threads, as desired. Still another process for fabricating a warhead body is presented whereby an insert section is first preloaded with metal fragments and covered with a skin, then the insert section is inserted into an oversized area in a mold, and polymer is then loaded around the insert section to form a unitary warhead body.
