Review of isostatic pressing methods

Abstract

In modern society, it is vital to improve quality process and in addition, to reduce cost. This paper is devoted to the production technologies of ceramic products of complex shape, namely, isostatic pressing methods. The information presented in the paper is intended to help the reader to get a sense of isostatic pressing methods; in addition, it can be used when choosing the production technology of an article made from powder materials. The paper describes the main isostatic pressing methods of powder materials, namely, hydrostatic and gasostatic pressing, as well as various methods of quasi-isostatic pressing, which include pressing in thick-walled elastic shells, pressing in thermoplastic polymers and others. The characteristic features, applications, advantages and disadvantages of each method are presented and described. Particular attention is paid to the analysis of the possibility of a particular technology to produce ceramic products of complex shape. In addition, the study compares technologies included in the group of isostatic methods
