  • Patent number: 9027801
    Abstract: 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.
