High performance lubricant for warm die compaction

The powder metal (PM) industry is constantly striving to increase the density in components in order to improve the mechanical performance. High density can be achieved with a variety of different manufacturing methods; however, warm die compaction has become popular due to the simplicity of the process. Using specially designed lubricants and heated tooling, high density can be achieved in a single compaction step. A new lubricant system has been developed which provides improved density and ejection performance. The optimal operating conditions and achievable properties of the lubricant system will be discussed.
