Metal Injection Molding
The Metal Injection Moulding process (MIM), considered as a development of the Powder Injection Moulding (PIM), became, over the years, a competitive manufacturing process for small components, offering an alternative to other processes, more expensive to create these parts.
History of the technology

The PIM process was at first developed in the 1930s in the USA. This process was originally intended for ceramics.
Then, during the Second World War, metal powders appeared. The process of Metal Injection Moulding was developed by Dr. Raymond E. Wich Jr. during the 1970s and became then an industrial process.
Afterward, the MIM process spread in Japan and finally in Europe. (M. Martin, 1999)
The context of its invention
Historical Context

In the 1940s, conventional powder metallurgy was developped in Germany before the Second World War. Later, in Sweden, the company Högänas developed pure iron powder that could be pressed and sintered to small mechanical components. But this material contained pores at this time.
After the war, various alloys were used as powder metal which enhances the properties of the final part.
In parallel, the "atomize" technique was developed : a jet of metal was crushed into a mold. But this technique results in part still with pores. Moreover, it cannot be used for high-alloy metal.
In the 1950s, the automotive industry used a lot of powder metal, especially the US market, followed by Europe and Japan. In parallel, the atomization with pure gases (argon, helium or notrogen) was developed.

In the 1960s, a new process, using gas under pressure that presses the metal powder into a mold, was enhanced. It is the Hot Isostatic Pressing process (HIP).
In the 1980s, the MIM process was invented and developed in California. Small components were made thanks to the MIM process while large components were made with the HIP process. (Metec, 2013)

    Copper was the most important metal used in early times. The alloying of copper to produce bronze represents a significant step forward in metallurgical practice: the resulting alloy is both stronger and less brittle than copper alone. There are a variety of different methods by which metal and metal artifacts can be produced or manufactured. Casting using the lost-wax method was an…

    Track and Field events, also known as athletics, have progressed a great deal since their birth in Olympus, around the ninth century B.C. More athletes and more nationalities compete in Track and Field than in any other Olympic sport. Athletics is one of the largest attractions at the Modern Olympics, drawing in huge crowds of spectators and creating interest at summer Olympics. Track and Field events have come a long way since the Ancient Greek Olympic games. Many events and techniques have been revised, added, or eliminated since the original Greek Olympics. The Olympic motto, "Citius, Altius, Fortius" is describing the Track and Field events in Latin. The Latin means " Faster (Swifter), Higher, Stronger," and indicates the running, jumping, and throwing events.…

    On Monday September 26 we toured PCPM. I found out they specialize in plastic injection molding and have been in business since 1978. At the beginning of the tour we were informed on the process the plastic goes through from the time it enters the factory in pellets to the time it leaves as a finished product. When we actually toured the factory it was difficult to hear our tour guide but I believe heard him say they add nylon to the plastic for certain molds to make it stronger. Seeing the molding process take place was pretty interesting, by making each mold one at a time PCPM ensures the quality of everything that leaves their warehouse. I missed quite a bit of the middle section of the factory tour because I couldn’t hear but I was especially fond of the new ecoflaps PCPM is producing. That is something I’ve never thought of before and it’s nice to know things like that are made here in Putnam County. What they do at PCPM is a pretty complex operation, with all of the different plastics they have to keep separate and at different temperatures it is quite a task. The variety of products that are made by PCPM must require a lot of skilled management to keep things running smooth.…

    The invention of epoxy resin has undergone a long period of time. As early as 1891, the German Lindmann hydroquinone and epichlorohydrin with the reaction of condensation into the resin and make use of anhydride curing. But its value has not been revealed. Epoxy plastic has its roots far back in history, to be specific, in 1936, when Dr. Pierre Castan in Switzerland succeeded in synthesizing an epoxy resin that he hardened with pthalic acid anhydride. Dr. Castan's work was licensed by Ciba, Ltd. of Switzerland, which went on to become one of the three major epoxy resin producers worldwide. Ciba's epoxy business was spun off and later sold in the late 1990s and is now the Advanced Materials business unit of Huntsman Corporation of the United States.…
