Apparatus for making bars from powered metal

摘要: Powdered metal is continuously introduced into a die cavity in discrete quantities and compacted bar segments to form bar. The has fixed cross-sectional area open at both ends, except during the initial compaction when one end closed. After formation of length bar, frictional resistance between wall relied on so that remaining serves as stopper for subsequent compactions powdered continuous forced out may be passed through an induction furnace sintering, swager, all preferably operation. Also provided means varying lengths formed from are bonded substantially uniform physical characteristics along its length.
