Continuous developments in the field of powder metallurgy allow the production of parts with increasingly narrower dimensions and weight, at an ever increasing rate of production. Complex parts with thin walls can be manufactured today by use of multi-stage press adapters and tools. The residual magnetic fields amplified in small air gaps, will thus impact progressively the compacting process of ferromagnetic powders.
This paper discusses the advantages of using completely demagnetized tools in the ferromagnetic powder compacting process.
