Metal injection molding can be abbreviated to MIM. The process of metal injection molding is a powder metal process. It is characterized through forcing metallic feedstocks under pressure into its tool cavities. This particular process is similar to injection molding. But it is using powder metal feedstocks. A green part is fed through a ‘debind’ process. This is followed by sintering. This is done to produce the high strength metal part.
A tool cavity is created when two hardened tool steel dies have been machine molded into its shape. The majority of metal injection molded parts will have been made from stainless steel alloys. But note that other materials are being used. Titanium is one example. Benefits accrue for the industrialist who discerningly chooses to place his stock into taking full advantage of the MIM processes.
One of the biggest advantages, however, remains that of the production of intricate parts in steel and metal that simply cannot be die cast or machined anywhere else. Secondary operations in place included that of plating and finishing work, all done in-house in order to produce the finished part. And the machines being used in metal injection molding (MIM) processes include sixty, one hundred and one-fifty ton injection molding machines.
Materials being used by the MIM operators have been coded. Examples of this coding system include SUS 316L, SUS 17-4PH and panacea. Interested readers and industrialists are well positioned to learn all about what kind of alloys will be applied to their specific areas and the standard tolerances being applied. The information is all there, online. There should also be recorded demonstrations on examples of the stages being followed during metal injection molding work. And guidelines are also given on how to submit existing specs to a selected machinist.
