... 8.7 is an example of a block mold analysis that predicted the potential shrinkage at the rim–spoke junction. Water-cooled Anviloy chills were designed at the rim–spoke junctions. The analysis also showed that the hub runs very hot. This prompted the design of a top cooling ring on the hub that helped...

..., there is general agreement about what leads to a good adhesive bond. Surface roughness plays a key role. The rougher the surface, the more surface area is available for the liquid adhesive to penetrate and lock onto. However, for this penetration to be effective, the adhesive must wet the surface, a function...
