Design for Soundness

Most metals and alloys shrink when they solidify. Therefore, design components so that all members of the parts increase in dimension progressively to one or more suitable areas where feeder heads (risers) can be placed to offset liquid shrinkage (Fig. 1).

Fig. 1: These illustrations portray how design can be used to rectify metal shrinkage defects. To ensure a component is free of shrinkage porosity, design components so that heavier sections are close to risers that can feed liquid metal to them.
