Abstract
Device for improving the quality of light metal castings which are cast into plastic moulds. The device fits into the pouring hole of the mould and has a number of basins for the ingress of metal corresponding to the number of components to be cast in the particular mould. Air is thus able to escape from the mould and the qualtiy of the castings is improved. The device is made of any suitable material which can be accurately worked and is able to withstand the temps. of casting.
