Abstract
A divisible slip-casting mold has filter layers which incorporate a combination of different types of fluid-flow conduits to improve the mechanical strength of the mold while providing the filter layers with substantially uniform fluid-flow properties. The conduits include major portions of blind holes installed in straight lines and minor portions of porous ropes arranged in curved lines. The porous ropes are essentially installed in those portions of the filter layer having a mechanical strength which is inferior to the predominant portions of the filter layer, and the blind holes are essentially installed in the predominant portions of the filter layer. Thus, improved mechanical strength and substantially uniform fluid-flow properties are provided substantially throughout the filter layers of the mold.
