Volume 2, Issue 12 , 2017, Pages 761-768

https://doi.org/10.5185/amp.2017/873

Abstract
  Regardless of high demands on properties of powder injection molding (PIM) compounds, there is still uncertainty in the role of the polymer binder in the process. To a great extent this is caused by the relatively low number of suitable direct methods to observe the interactions among binder components ...  Read More
