MIM Systems Ltd has developed new technology to produce plastic injection molds based on the Metal Injection Molding process. This is a rapid tooling method which allows tooling production time to be cut by a factor five to ten and tool price by half compared to traditional methods. The molds produced by this technology, called Mold in Mold, are made out of steel, hence they have mechanical characteristics similar to the production tools used today. Moreover, the mold in mold technology also speeds up the tuning of the molds required to optimize parts production. It is especially efficient for the production of parts with very elaborate geometrical features. By reducing the tooling price, the production of small or limited series of parts by injection molding becomes economically feasible.
