Abstract

Det beskrives en støpeapparatur som omfatter et overføringselement (12) som har et ventehulrom (14) der i til mottak av en ladning av støpbart materiale. Støpbart materiale i kornform eller smeltet form mates inn i en oppvarmet passasje (30) av en materspiral (40) i et rør (36). Et stempel (42) forflytter smeltet støpbart materiale langs passasjen (30) og inn i ventehulrommet (14). Overføringselementet (12) forflyttes deretter til en posisjon hvor i ventehulrommet (14) er på linje med en åpning (18) i en bæreplate (16). Åpningen (18) er i kommunikasjon med et støpehulrom (20) som har formen til den artikkel som skal produseres. Et andre stempel (46) forflytter ladningen av støpbart materiale fra ventehulrommet (14) gjennom åpningen (l 8) og inn i støpehulrommet.
