COMBRINCK, J.; BOOYSEN, G.J.; VAN DER WALT, J.G. y DE BEER, D.J.. Limited run production using Alumide® tooling for the plastic injection moulding process. S. Afr. J. Ind. Eng. [online]. 2012, vol.23, n.2, pp.131-146. ISSN 2224-7890.
Existing techniques for the production of conventional steel tooling for plastic injection moulding are expensive and time-consuming. As a result, many new products often do not advance beyond the prototype stage. This paper describes an investigation into the possibility of using laser sintered Alumide® (an aluminium-filled nylon material) in a novel alternative process for producing hybrid rapid tooling tools. Initial experiments performed by researchers at the Central University of Technology have shown excellent results. An Alumide® tool can be manufactured in a shorter time and at a significantly lower cost than the same size direct metal laser sintered tool.
