There are two main types of MIM
injection molding powders. They are water atomized powders and gas atomized
powders. Following analysis of the
composition and morphology for those two
powders are from a Shenzhen MIM injection molding manufacturer ZCMIM .
Water Atomised powders for Metal Injection Molding
MIM
l Irregular shape
l High proportion of
oxide particles/impurites
l Thick oxide layer,
rich in SiO2
l Low packing density
Gas Atomised powders for Metal Injection Molding MIM
l Regular, spherical
shape
l Low proportion of
oxide particles/impurites
l Thin oxide layer,
typically ~2nm
l High packing density
~65% theoretical max
