Metal Injection Molding for Superalloy Jet Engine Components

摘要

The Metal Injection Molding MIM process is a combination of powder metallurgy technologies and the shape making capability of plastic injection molding. Major market segments for MIM are consumer electronics, automotive, firearms and medical. MTU Aero Engines GmbH advanced the MIM process using high temperature superalloys powders. Optimized thermal processes and superalloy powders utilize nearly the full potential of the superalloys challenged by the required high dynamic strength and aerospace quality. Compressor vanes and small retainers are now proving their quality in a test engine accompanied by the evaluation of material data. The development of MIM super alloy aerospace parts emerges the usage of MIM to more technically sophisticated applications.
