The cavity powders specially developed for the aluminum industry are available ready-to-use and are applied over the entire area of the feeder (s) after the liquid metal has been poured. The fine powder ignites automatically, then slowly burns off with the release of heat and ultimately forms a solid crust.
For application to risers in sand casting for all alloys to effectively increase the riser effect. Blowhole powders are used to cover and insulate the exposed feeder surfaces in open feeders. They also reduce the rate of cooling of the metal in the risers by exothermic reactions. This can ensure that the feeder solidifies last and that there is always sufficient liquid metal for refeeding. Sprue hoppers can also be heated exothermically for the purpose of refeeding.
