faqs
1. what is mimtechnology?
mim (metal injectionmolding) is a manufacturing technology that combines theshape making complexity of plastic injection molding with thematerial flexibility of powder metallurgy.
2. is the metal melted during the moldingprocess?
no, only the bindersare melted allowing the powders to flow like a plasticmaterial. upon cooling the binders solidify giving the partstrength for handling. the part must be subsequently sintered tohigh density to achieve the required mechanicalproperties.
3. how does mim differ from the conventional pmprocess?
conventional pm uses high,uniaxiallyappliedpressure to coarse metal powders in a die set to produce moderatelycomplex components. typically, no further densification is gainedduring the sintering process. densities achieved by this method aretypically in the range of 80-90% of theoretical which limit thephysical properties that can be achieved for the given alloy.mim products are not limited in shapecomplexity due to the flexibility of the injection moldingprocess. the fine metal powders used - combine with higher sintering temperatures to allow mim toachieve near full density in the final article. thisallows mim products to have similarproperties as wrought materials.
4. does the part shrink during removal ofbinders?
no, the part will not change size inthedebindingphase of theprocess. however, since sintering achieves near full densityof the powders, the part will undergo a size change of up to20%.
5. why should i use mim?
mim excels in producing small, highlycomplex parts that are difficult or cost prohibitive to producewith conventional technologies such as machining orcasting.
