Polymer Technologies Inc. (PTI) has selected the Moldflow Plastics Insight (MPI) software from Moldflow Corp. to analyze a sophisticated part made out of a nickel-based super alloy for an aerospace manufacturer using a Metal Injection Molding Process (MIM). MIM is a high-volume process that helps eliminate secondary machining operations for metal part production and a method of fabricating intricate net shape metal, ceramic, and metal ceramic components using technologies more commonly associated to the plastics industry.

Dr. Jerry LaSalle, PTI's director of MIM operations, and Boris Chernyavsky have been using MPI for several years for tooling design and mold simulation. LaSalle says, "MPI is being used to simulate mold designs before the tool is actually built. The simulations help us determine different gate designs and locations, placement of cooling lines, and melt overflows. MPI allows us to design the tool for maximum compatibility with the MIM feedstock before incurring the expense of a costly tooling mistake or an unacceptable design. It also allows us to troubleshoot. Many of the materials we use are very expensive. Therefore, less time on the production floor working through a problem saves labor and material costs."
