Studies on the mouldability of structural foams in hybrid moulds
Nogueira, A. A.; Martinho, P. G.; Brito, A. M.; Pouzada, A. S.; Gago, P. T.In the context of the research project Hybridmould 21, studies on the mouldability of structural foams using hybrid moulds have been carried out. Hybrid injection moulds are an increasingly considered alternative for prototype series or short production runs of large dimension parts. In this solution for injection moulds the moulding elements (blocks or other inserts) are manufactured in alternative metallic ma...
Rapid prototyping and tooling in the manufacture of mould elements for large parts
Freitas, A.; Soares, Rui; Martinho, P. G.; Pouzada, A. S.In the last two decades the advances in rapid prototyping and tooling (RPT) technologies made possible the use of materials alternative to steel in some mould components. They also have allowed novel fabrication strategies and new ways of thinking on the production of injection moulds for short series of plas-tics parts. These technologies induced a new generation of toolmaking techniques. In the scope of the d...
Mechanical design of hybrid moulds : mechanical and thermal performance implica...
Martinho, P. G.Tese de doutoramento em Ciência e Engenharia de Polímeros ; The design and manufacture of injection moulds are the most time-consuming phases in the development of new plastics products. In the last two decades the advances in rapid prototyping and manufacturing technologies made possible the use of materials alternative to steel in some mould components. The integration of these components with conventional m...
A new way to produce conformal cooling channels by RPT for moulding blocks of t...
Nogueira, A. A.; Pouzada, P. S.; Martinho, P. G.; Pouzada, A. S.Prémio de melhor artigo com interesse para a indústria. ; Hybrid moulds are an increasingly considered alternative for prototype series or short production runs. In this solution of injection moulds the moulding elements (blocks or other inserts) are manufactured in alternative metallic materials or in synthetic materials. One of the main issues associated to the use of these alternative materials is their the...
