The paper describes how a stream-lined gating system where the melt is confined and
controlled during filling can be designed.
Commercial numerical modelling software has been used to compare the stream-lined
design with a traditional gating system. These results are confirmed by experiments where
the two types of lay-outs are cast in production.
It is shown that flow in the stream-lined lay-out is well controlled and that the quality of the
castings is as at least equal to that of castings produced with a traditional lay-out. Further,
the yield is improved by 4 % relative to a traditional lay-out.
Key words: Gating systems, Melt flow, Casting quality.
