FIELD: foundry.
SUBSTANCE: feeding system comprises head (10) installed on rod-bridge (11). Head has first end (12) and opposite second end (13), longitudinal axis (A) passing between these ends, and continuous side wall (14) passing around longitudinal axis, forming cavity for receiving molten metal during casting. Rod-bridge limits open hole for connection of cavity for receiving molten metal with formed casting. First end of the riser has a lower part installed on the connecting rod. Second end of the riser comprises a flat upper part (16) and curved (15) or bevelled part passing along the periphery of the upper part, connecting the side wall and the upper part.
EFFECT: reduced risk of rupture of polymer film at its tension on model during vacuum forming.
