View Full Version : First 1911
5th December 2011, 01:18
Picked up my first 1911 today, it's a Ruger SR1911. Apparently these things are hard to get ahold of... I went into the PX today and low and behold they had one so I talked it over with the wife and about 20 mins later I walked out with it. Been wanting a 1911 for a while after shooting my friends but didn't know what to get, went to the local stores and heard wind of the Ruger and decided to wait for it to come out.

been stalking around the forum a bit and keep seeing MIM, what does it mean? I tried looking for an abbreviations thread but wasn't able to find one.

MIM stands for Metal Injection Molding. It is a relatively new process that allows metal parts to be molded using the same basic process as injection molding of thermoplastic parts. The metal particles are given a thin coating of material with a low melting temperature. This material is then heated to liquefy the coating allowing the particles to flow into the injection mold. After cooling the molded part called a "green part" is ejected from the mold. The green part is held together by the solidified coating and is about 20% bigger in size than the final part. The green part is then heated to a high temperature to drive off the coating and fuse the metal together. The finished part is the correct size.
MIM allows molding of metal parts in low cost tools. The metallurgy can be adjusted to get high quality parts that require less machining and therefore have a lower labor cost than fully machined parts. It makes sense when high volumes can justify the tooling.

Welcome to the forum.
For the record, MIM is also used in many industries, in applications that can't be described as 'low quality'... e.g. jet engine turbine blades. Please browse the forum for discussions on the matter.
