Abstract

The funnel- or bowl-shaped insert for hollow charges consists of a hollow body (10) which is produced and shaped from a copper monocrystal obtained through crystal growth. The growth orientation is the (111) main orientation. It coincides with the longitudinal axis of the hollow body. For production using the Bridgman zone melting process a mould is proposed consisting of an inner and outer mould section (18, 20). Both mould sections may be moved axially in relation to each other and will be brought into their terminal position determined by stop (26) during the melting process.
