With the use of nano-silicon powder, the arcuate back 58 may be tightly fit into the corresponding portion of the base mortise hole with only a very small layer of adhesive filling the gap. An improved leg 70 of a second embodiment illustrated in the axial cross-section of FIG. 7 is ...
In order to minimize this imbalance, the flow path of the second material needs to be determined so that the pressure on the all sides of the core at any given timing of the filling could cancel each other. For example, when the melt front advancement in the front side of the core and...
