Abstract

Binder removal approaches involve various combinations of heat, solvents, vacuum, and pressure. In each variant, the goal is binder removal without component damage. This chapter addresses the factors that control success, showing how process decisions depend on the powder and binder characteristics. The chapter starts with a comparison of binder-, lubricant-, and polymer-removal situations that arise after powder shaping and then describes the general principles of binder removal in powder-binder techniques. The subsequent sections discuss in detail characteristics, operating procedure, equipment setup, advantages, limitations, and applications of first- and second-stage binder removal processes, as well as the factors influencing these processes. Cost issues associated with binder-removal technologies are also discussed.
