A centrifugal injection machine comprises a rotor arm bearing at each of a pair of free ends a pivotably mounted container. A holder which retains a multiplicity of workpieces is insertable into a capsule or cavity within each container. The rotary arm contains a reservoir associated with each container or liquifying a charge of material. Upon rotation of the machine at a high velocity, the liquified material is transferred from the reservoir to the container in a vacuum and is pressurized therein as a result of centripetal acceleration. Upon the termination of a predetermined interval, a trip mechanism is activated to rotate the containers so that the molten liquid which has not been injected under pressure into recesses in the workpieces is ejected or discharged from the containers. The containers rotate within a vacuum chamber which is depressurized prior to the centrifuge operation.

An apparatus for injecting a first metal into thin plate-shaped recesses in a workpiece body to form electrode plates in a multilayer capacitor, said workpiece body having capacitor terminals formed of a second metal, said second metal having a higher melting point than the melting point of said first metal, said apparatus comprising: a frame; a boom rotatably mounted to said frame; drive means operatively linked to said boom for rotating same about an axis of rotation at a high speed, said boom having at least one free end spaced from said axis of rotation; a carrier member pivotably mounted to said boom at said free end, said carrier member being provided with a pressurization recess having a mouth and a closed end opposite thereto; retaining means disposable in said pressurization recess for retaining therein a multiplicity of workpiece bodies each formed with a plurality of thin plate-shaped recesses and having capacitor terminals formed of the second metal; feed means provided on said boom for feeding the first metal in liquified form to said recess through said mouth; heating means including heater elements disposed in said carrier member in juxtaposition to said pressurization recess for supplying thermal energy to the liquified first metal in said recess to maintain the first metal in liquified form during a metal injection phase of an operating cycle; counterweight means operatively coupled to said boom for balancing the mass of said boom and said carrier means with respect to said axis of rotation; and actuator means operatively coupled to said carrier member for pivoting same from a first angular orientation, in which said mouth and said closed end are aligned in a direction perpendicular to said axis and with said mouth being disposed between said closed end and said axis, to a second angular orientation in which said mouth and said closed end are aligned in said direction and with said closed end being disposed between said axis and said mouth, whereby centripetal acceleration of said carrier member during said metal injection phase of an operating cycle causes a pressurization of the liquified first metal in said pressurization recess to force the first metal into said plate-shaped recesses of said ceramic bodies and whereby the liquified first metal is ejected from said pressurization recess during a discharge phase of an operating cycle.
