Hollow charges are often used for combating moving, lightly armored targets and do not fulfill their task due to relatively small effective charges which arrive at the target. When using blasting charges for civilian purposes, large borings must often be made at inaccessible positions without substantially affecting the environment. A shape charge ( ) having a lining ( ) which explodes outward in the axial area thereof punches an overcalibrated opening in the target area. A large effective charge ( ) or other elements can be inserted through said opening. According to the invention, the delayed ignition of a large effective charge ( ) results in a massively increased effect thereof in the target. The ammunition body ( ) is provided for use predominantly in combating moving, lightly armored targets, but can also be used for oil exploration and delivery.

Ammunition body, a method for inserting, and its use

A water-filled pressure chamber (7) loaded by conventional pumps at pressures of several thousand bars is used to isostatically press explosive charges. Inside this pressure chamber (7) is a compression mold (6) having an inner/outer mold (1) consisting of several components. Explosives in the mold are subjected through an elastic sleeve (3) to liquid pressure (p), so that the interior pressure in the chamber will be nearly isostatic. Following pressure relief, Dimensionally accurate and homogeneous precision explosive charges are obtained. The present invention also includes the process using the pressure chamber. The invention increases manufacturing output and quality of explosive charges so produced.
