Bu çalışmada, yaş kum kalıplar kullanılarak geleneksel yerçekimi (gravity casting) ve yerçekimine ters döküm
(counter gravity casting) yöntemleri ile üretilen parçaların besleme özellikleri üzerine döküm sıcaklığı ve basıncın etkisi araştırılmıştır. Deneysel çalışmalarda Al-% 10 Si döküm alaşımı kullanılmıştır. Numuneler 600, 640 ve 690 °C sıcaklıklarda, 100, 200, 250, 300 ve 500 mmHg vakum seviyelerinde dökülmüştür. Sonuçlar, yerçekimine ters döküm yöntemiyle gelişmiş besleme özelliklerinin elde edildiğini göstermiştir.

In this study, effect of casting temperature and pressure on feeding properties of specimens produced by green
sand mould traditional gravity casting and counter gravity casting was investigated. In experimental study Al -
10 % Si casting alloys was used. the specimens were poured at 600, 640 and 690 °C temperature, under 100,
200, 250, 300 and 500 mmHg vacuum level. the results showed that improved feeding properties were obtained
by Counter Gravity Casting process.
