New Process for Fabrication of Microcomponents Using Metal Nanopowder

摘要

A new process to manufacture small parts was developed using two kinds of polymer, SU-8 for a master mould and Polydimethylsiloxane (PDMS) for a soft mould, and the small parts produced via the new process were investigated in physical properties, such as density and shrinkage. PVB(polyvinyl Butyl) is proper use of binder to fabricate a microcomponent in the new process. Relatively clear shape of green component could be achieved by using the new process, but physical properties for the sintered ones were not enough to produce good microcomponents. In order to apply the new process to the fabrication of microcomponents, more advanced studies should be performed for enhancing the density of the sintered components by increasing compaction intensity of powders into a PDMS soft mould.
