Polymer Technologies Uses Moldflow PlasticS Insight to Develop Sophisticated Aerospace Component Using Metal Injection Molding Process



WAYLAND, Mass.--(BUSINESS WIRE)--Jan. 7, 2003--Moldflow Corporation (NASDAQ: MFLO), the world leader in process wide solutions for optimizing the design and manufacture of plastic products, today announced that Polymer Technologies, Inc. (PTI) is utilizing Moldflow Plastics Insight(TM) (MPI(TM)) software to analyze a sophisticated part made out of a nickel-based super alloy for a leading aerospace manufacturer using a Metal Injection Molding Process (MIM). MIM is a high-volume, high quality, cost-effective process that helps eliminate secondary machining operations for metal part production. MIM is a unique 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."

Recently, LaSalle and his colleagues used MPI on an aerospace flow body part that directs jet engine exhaust to other parts of the plane such as heating the passenger cabin. He adds, "The part is very difficult to machine. Thus, conventional methodologies would hinder our efforts and likely incur additional costs and headaches. By molding this complex, 1.7-kilogram part to a more nearly net shape, significant machining costs can be saved. MPI simulation was critical in assisting with gate design and prediction of knit lines."

Ken Welch, Moldflow's executive vice-president of marketing and field services, adds, "Clearly, PTI is representative of the increasing number of manufacturers that are using computational and analytical techniques to reduce design time and costs while significantly improving yield and quality. We are quite pleased with PTI's sophisticated approach to product design and development using MPI."
