SURFACE FINISH
Surface finish of MIM parts is approximately 32 RMS (0.80 micrometer), appreciably better
than most investment castings. However, profilometer readings may be affected by residual
porosity and are subject to interpretation. The method of measuring surface finish should
be agreed upon by both the customer and vendor. The surface of MIM parts can be improved by
conventional processes such as grinding, lapping or burnishing.
