whats the difference in MIM and cast parts ?? thanks jwr
MIM parts are metal mixed with plastic, and then are injected into molds.
There is no plastic in a MIM part.
The process involves combining fine metal powders with a plastic binders which allow the metal to be injected into a mold using standard plastic injection molding machines. After the part is molded and before the binders are removed, the part is referred to as a 'green part'. The next step is to remove the binders with solvents and thermal processes. The resultant metal part is sintered at temperatures great enough to bind the particles but not melt the metal. The products of metal injection molding are up to 98% as dense as wrought iron and used in a broad range of applications (including medical, dental, firearms, aerospace, and automotive just to name a few.)
thank you for the replys,every little bit helps.FWIW I did do a search,but unlike someone said "search is not my friend" Mr. Computer is not my friend.we just barely get along. when all else fails I ask. jwr
I don't understand why your question was challenged. Sometimes asking instead of Googling is profitable to everyone.

Most important lesson in this thread.I don't understand why your question was challenged. Sometimes asking instead of Googling or FAQing is profitable to everyone.
