MIM represents the most cost effective manufacturing approach for small intricate metal components that are required in medium to very high volumes. Imagine how many machining operations would be required to produce the shape if it were to be machined.General, MIM is the preferred process for component designs that would require 4 or more machining set-ups or operations. Keep in mind that machining adds incremental cost for each machined feature, while the molding process used in MIM adds very little or no incremental cost for each molded feature.


The following is a list of general characteristics that describe good MIM applications:
Some parts

  • engths to 7 inches
  • all thickness to 0.5 inches
  • eights above 100 grams
  • olumes as low as 5,000 annually

Most parts

  • engths less than 3 inches
  • all thickness from 0.04 to 0.12 inches
  • eights under 60 grams
  • olumes of 100,000 to >100,000,000 annually
