When performed by experienced mim parts manufacturers,
Metal Injection Moulding offers a combination of features which
can translate to cost-saving benefits:
As the parts is formed by injection, there are virtually no
design restrictions. Actually, geometry complexity and intricate
shapes are required in order to appreciate the cost-effectivness
of the MIM process. However, there are some designing rules that
you can easily get from our Engineering Dept.
Costly machining operations are reduced because of the high
geometrical complexity and tight tolerances that can be reached
with MIM. MIM is a typical near net shape parts manufacturing
The best tolerance range is ±0,3% of nominal dimension, with
a minimum of ± 0,04 mm for dimensions which are less than 3 mm.
The reduction in tolerances is not directly proportional to decreasing
dimensions and may depend on part shape, material, and process
QUALITY SURFACE FINISH
Surface finish of MIM parts is approximately 1 µm, appreciably
better than most investment castings.
achieves densities up to 99.5%. Unlike conventional press and
sinter P/M, MIM components can be plated, coated, heat-treated,
just like wrought alloys.
