ENGINEERING SUMMARYEngineering summary

Selecting a MIM feedstock requires joint consideration of the metal powder, binder system, solids loading and rheological process window. The grade or D50 value alone is not enough.

ENGINEERING EXPLANATION

Interpret the relationships between variables, not a single parameter

Explain how powder size, morphology, and packing interact with binders, solid loading, and MIM rheology.

01

Powder determines the feedstock basis

Particle size distribution, morphology, specific surface area and powder packing state can affect binder requirements, mix uniformity, viscosity and risk of powder-binder separation.

02

feedstock connects four processes

Compounding, granulation, injection molding, debinding and sintering are interrelated. Over-adjusting one of these variables in pursuit of fill may shift risk to the debinding or sintering stage.

03

Inquiries require feedstock system

When discussing powder for MIM, provide the binder type, solids loading, compounding and injection conditions, and details of any short shots, flash, separation or dimensional issues.
