High-Speed Centrifugal Compaction Process (HCP) is a kind of wet compacting method for fine powders. One of possible applications of this technique is a net-shape fabrication of complex shape parts, especially including hollow shapes. For such application, we have developed HCP with cores but the compact was easily cracked and chipped because of insufficient green strength. Therefore, in this study we aimed to develop new slip system which enables to provide strong green compact. We revealed adequate combination and composition of dispersing medium, agent and binder resin for metallic powder slip. The HCP green compact of this slip system provides crack-and-chipping-free green compacts with cores, with packing density above 60%.
