Abstract
A divisible slip-casting mold has filter layers which incorporate a combination of different types of fluid-flow conduits to achieve improved fluid-flow properties. The conduits include major portions of porous ropes arranged in curved lines and minor portions of blind holes installed in straight lines. The porous ropes are essentially installed in those portions of the filter layer where the ropes are readily or uniformly arranged, and the blind holes are essentially installed in those portions of the filter layer which exhibit poor fluid-flow properties and in which installation of porous ropes is difficult. Thus, substantially uniform fluid-flow properties are provided in the filter layers of the mold to enhance mold casting performance.
