- MIM Parts Question - 1911Forum
The problems with MIM parts in guns boils down to choosing some parts that are incompatible with MIM (Colt extractors come to mind)and bad manufacturing processes that stem from going wih the lowest bidder Not all MIM is equal Most manufacturers have figured that out now and it is a pretty well settled debate Do I like MIM? No Does it work

How can I tell if my Tisas has MIM parts? Of my four Tisas models three of them say "TISAS KNOXVILLE TN" and one says "SDS KNOXVILLE TN" I suspect that the model labeled SDS still has MIM but I am not sure
- MIM parts? - 1911Forum
MIM, forged, machined, cast—they can all be done right, and they can all be done wrong Kimber and Smith of certain eras were bad MIM Metal sintering reduces dimensions and still requires deep surface hardening Do it wrong, and you get undersized dimensions on some parts and thin surface hardening that wears uncommonly fast
- What are MIM internal parts? - 1911Forum
MIM is Metal Injection Moulding I't a step up in the "sintered metal" process of producing a part that is close to if not dimensionally correct without extra machining It works like this; powdered metal (or metals if you want an alloy) and an adhesive medium are pumped into a mould and heated under pressure until a bonding occurs, and the adhesive cooks out, leaving you with a "finished

- 1911 Mim extractor, replace or not? - 1911Forum
MIM is powdered metal pressed into near net shape, then sintered (heated enough to melt only the outer surfaces of each powder particle) This precludes grain growth throughout the finished part, effectively creating a part that has grain refinement without multiple grain reduction stages through rolling, extrusion or forging
