MIM, Metal Injection Molding ?
If not use it in a sentence...

MIM=metal injected molding. What they do is take a powder form of metal mixed with a plastic and heat it until it flows. They then force it into a mold under pressure. The plastic is consumed by the process. The advantage of this is that all of the parts come out exactly the same and require little or no hand fitting. With a machined part there is ware and tear to the machine which causes variances between parts. This then requires each part to be hand fitted. The MIM parts have no variance from part to part. Some say that machined parts can be smoothed out better than MIM. I don't necessarily agree with that. I think that any real difference only exists in the minds of the so called experts.

MIM is simple and complex at the same time. If you want to wrap your mind around powder metallurgy, you have to understand that the powdered metal that all MIM parts are made from isn't melted. That point is often lost. If the metal is melted and poured (or injected) into a mold..it's a casting. Cast metal and sintered metal are completely different structures. The powdered metal in a MIM part is tricked into forming a bond by manipulating the molecules using heat (about 80-85% below melting point) and atmospheric control. The surfaces of the tiny metal particles will diffuse into each other, but this bonding is only a few molecules thick. This is why MIM parts have the properties of wrought metal, the particles are wrought, and since they do not melt, the wrought structure does not resolidify and transform into a cast structure.

I think the process was invented to form the impeller blades in jet tubine engines years ago.

Interesting. I thought it was invented because the forum put a lock on further discussion about the internal lock.

I found this video to be informative.

And simple. Simple is good for me.

Also I'll point out that on newer Smith & Wesson revolvers the most visibly noted MIM parts are the trigger, hammer, and thumb release latch.

It stands for: Let's make more parts faster and cheaper and charge people more.

Yeah, there's plenty with engineering degrees.

Those were the guys in high school who were paying attention in algebra class instead of thinking about how they could blow out and go bird hunting!

If you're talking about current production Bianchi holsters, it means Made In Mexico.

"Much Inferior Metal" perhaps?
