New process for fabrication of microcomponents using metal nanopowder

Lee H.M., Choi C-J, Korea Institute of Machinery and Materials, KR

We developed a new process to manufacture a soft mould for the small parts using two kinds of polymer, SU-8 for a master mould and Polydimethylsiloxane (PDMS) for a soft mould and produced the small [...]

Fabrication of microcomponent using Fe based nanopowders

Choi C-J, Lee H.M., Korea Institute of Machinery and Materials, KR

The metallic microcomponents were fabricated by pressureless sintering of nano-sized pure Fe and 17-4 PH stainless steel nanopowders. The compacting and sintering behaviors of nanosized Fe powders have been evaluated and compared with those of [...]
