Abstract

Known projectiles with molded fragments are usually produced in the shape of steels or rollers produced with the aid of powder technology or in a flow compression process. The molded fragments are located in a dense packing in the wall of fragmentation bodies without being able to be brought into an orientation which is advantageous for the fragmentation effect. In order to enhance the fragmentation effect, the fragments are arranged with regard to their orientation and mutual spacing within a casting form in a pattern provided in an inner mold form, and subsequently provided with the cast material. Required through the form-fitting support of the fragments through protuberances projecting into the fragments, after the removal of the fragmentation body the recesses formed in the fragments can have incendiary charges pressed therein. Thereby the fragmentation is enhanced by the additional incendiary effect.
