The best metal injection work delivered comes by way of molding processes. To be sure, metal injection molding or MIM as it is abbreviated, has been done and dusted for many years now. But surely to goodness, as would be the case for numerous industries today, yours too perhaps, new technologies and developments are making metal injection molding even better than it was the year before.
For all those that are still new to the production processes involved, metal injection molding is a powder metal process. It is characterized by way of forcing metallic feedstock under pressure into a tool cavity. The process is quite similar to injection molding processes with the difference being that it uses powder. A resulting green part is required to slot through a debinding process. This gets followed by a sintering process. This latter process is required to produce the metal part’s high strength.
A tool cavity gets created by using two hardened tool steel dies. These dies have already been machined into its required shape. The majority of MIM parts have been fashioned from stainless steel alloys. But it is no longer uncommon for exotic materials such as titanium to be used. A hot-chamber machine is being used for zinc die casting processes. A cold-chamber device is used for aluminum. The benefit of these casting processes is that zinc and aluminum die-castings can be mass produced.
Net shape parts are also produced. This results in a finished part that may require no further secondary processes. All tools built from steel can be reused. This makes it possible for die casting processes to mass produce parts at competitive prices for the commercial and industrial client. A streamlined production process delivers quick results for the clients.
