Application of laser additive manufacturing to produce dies for aluminium high pressure die casting

Author: Pereira, MFVT ; Williams, M ; Du Preez, WB Date: Jul 2012 A number of laser additive manufacturing (LAM) technologies can produce fully-dense metal components that potentially offer opportunities to apply the technology in die or mould making (known as rapid tooling). From these LAM technologies, ... Read more
Characterization of metal powder based rapid prototyping components under aluminium high pressure die casting process conditions

Author: Pereira, MFVT ; Williams, M ; Du Preez, WB Date: Nov 2009 This paper is based on tests performed on die component specimens grown on an EOS RP technology platform, as well as manufactured specimens machined out of preferred standard hot work steel DIN 1.2344. These specimens resemble typical components ... Read more
