Recent Advances in Dry-Bag Cip Equipment


Article Preview

Dry-bag CIP process has become a very popular method in the large volume production of powder compacts in the P/M and ceramic industries. Intensive technological research on the Drybag equipment has been carried out to improve the dimensional accuracy and the productivity. In this study, the rubber mold design technology with FEM simulation during pressing has been introduced, in order to achieve higher dimensional preciseness, and criteria for the selection of Drybag equipment, namely the In-line type or Off-line type, have been established based on the powder flowability index proposed by Carr. Based on these research results, high productivity Off-line Drybag CIP equipment, which can realize good dimensional accuracy with high productivity, was developed even for non granulated powders with poor packing density. This paper describes the research results and the present status of the most advanced Off-line Dry-bag CIP equipment technologies.
