μ-MIM® Technical Newsletter

In the previous report, we discussed the evaluation of metal powders. In the powder metallurgy industry, the process of kneading (mixing main raw material with sub materials) is unavoidable. This time, we will move on to the kneading stage.

It's been a while since the "I want to know but can't ask” series. We will discuss the basics, realities, and concerns of powder, which serve as the starting point for manufacturing, not only in the MIM industry but also in various other industries, over several issues.

Metal components manufactured by powder metallurgy tend to be regarded as having a low density compared to machined or stamped wrought material. Although, low density can be an advantage depending on the applications, but in general operations, high density is required to meet the mechanical strength requirements assumed in the design phase. In this issue, we introduce the characteristics of powder metallurgy from the perspective of density.
