Abstract (en)
A machine and a process for producing centrifuged castings of nonferrous alloys such as articles of costume jewelry, buckles, small metal parts and the like. The machine comprises a base (1) supporting rubber multiple molds (2) that are kept rotating and into which a predetermined amount of melted metal from a crucible (7) is injected at a central location. The device for feeding the melted alloy comprises a sleeve (8) with a movable plunger (9) that takes the liquid metal (6) from a side opening (12) and conveys it under pressure to the rotating mold (2) along a feeding conduit (5) that is substantially horizontal.
