Scaling down devices from the macroscopic world to microsystems presents various
problems since tolerances decrease down to the range of the surface roughness.
Consequently, the problems assembling such systems increase and any wear has an
extreme impact on the function of microsystems. Recently, most microparts are made of
thermoplastics or in brittle materials like silicon by deep etching. The mechanical properties
of these materials, however, are not favorable for microparts subjected to mechanical wear.
To meet the obvious demand for wear resistant microparts made of metals and ceramics,
the development of Micro-Metal Injection Molding (Micro-MIM)/Micro-Ceramic Injection
Molding (Micro-CIM) was started at Forschungszentrum Karlsruhe a few years ago. The
article describes special distinctions between Micro-Powder Injection Molding (μ-PIM) and
normal PIM as well as the arising process variations.
