Excellent surface finish
The surface quality of MIM parts is far superior to that of precision casting parts. Even without polishing treatment, a surface Ra < 1.2 is achieved. Thus, handling and polishing expenses can be eliminated or reduced considerably.
The MIM process allows us to achieve exactitude better than ± 0.5% of the desired size, without post-processing. This means that with extremely small parts, the tolerance is in the area of a hundredth of a mm. When working with parts that have very narrow tolerances or bigger dimensions, calibration or post-processing might be necessary.
