An elongate collapsible feeder element for use in metal casting and a feeder system with attached feeder element and feeder sleeve. The feeder element has an A end and an opposite B end measured along the height, and a C end and an opposite D end measured along the length. The A end is for mounting on a mold pattern or swing plate and the opposite B end is for receiving a feeder sleeve. A bore is between the A and B ends defined by a sidewall having a stepped collapsible portion. The feeder element is compressible in use to reduce the distance between the A and B ends. The bore is offset from the centre of the feeder element along the length towards the C end and a second sidewall region is non-planar, contiguous with a third sidewall region and located between the bore axis and the D end.

Feeder element

Fluid distribution feeder

Feeder element for use in metal casting, having a first end for mounting on a mould pattern or swing plate, an opposite second end including a mounting plate for mounting on a feeder sleeve, and a bore between the first and second ends defined by a sidewall. The feeder element is compressible whereby to reduce the distance between the first and second ends. The bore has an axis that is offset from the centre of the mounting plate, and an integrally formed rim extends from a periphery of the mounting plate.

The present invention relates to a feeder element () for use in metal casting. The feeder element () (which serves the function of a breaker core) has a first end () for mounting on a mould plate (), an opposite second end () for receiving a feeder sleeve () and a bore () between the first and second ends () defined by a sidewall (). The feeder element () is compressible in use whereby to reduce the distance between said first and second ends (). The invention also relates to a breaker core/feeder sleeve assembly ().
