Injection Molding Process and Properties

The compaction behavior of ceramic powders is reviewed from the viewpoint of the factors involved and how these relate to green microstructure. The basis for the observed linear relationship between the logarithm of compaction pressure and relative density is discussed, and five generic types of compaction behavior are presented. The relation of granule properties to compaction behavior, green strength and green microstructure are discussed. Die friction, springback, die filling and green microstructure evolution are reviewed, and the needs for a better understanding of pressing are discussed.
