Abstract(s)
A fabricação de moldes é um pilar da indústria metalomecânica nacional. A qualidade
patenteada pelos moldes de fabrico nacional é reconhecida mundialmente.
A fabricação de um molde é sempre um novo desafio, dadas as especificidades de cada
peça e à complexidade geométrica que normalmente apresentam.
Este trabalho teve por principal objetivo proceder ao projeto, fabricação e ajuste de um
molde para uma peça plástica complexa, destinada à indústria automóvel, a qual, pela
sua complexidade geométrica, elevada relação de área versus espessura e grande
número de reforços bastante delgados, exige cuidados especiais no momento de se
tomarem decisões quanto às melhores metodologias a adotar na sua fabricação, com
vista a garantir a qualidade exigida pelo cliente final. O projeto foi desenvolvido e levado
a cabo, permitindo constatar que algumas das opções tomadas na fase do projeto foram
as mais adequadas, exigindo pouco trabalho de afinação no final e permitindo a
extração de peças com elevada repetibilidade de características e a qualidade requerida
pelo cliente.
Moulds manufacturing for plastic injection is a pillar of the national metalworking industry. The quality patented by moulds manufactured in Portugal is recognized worldwide. The mould manufacture is always a new challenge, regarding the specific nature of each part and the geometric complexity typically featured. This work had as main objective to design, manufacture and adjustment of a mold for a plastic part, intended for the automotive industry, which, by their geometric complexity, area vs. thickness ratio and large number of reinforcements quite slender, requires special care at the time of taking decisions about the best methodologies to adopt in its manufacture in order to guarantee the quality required by the final customer. The project was developed and carried out, allowing see that some of the choices made in the design phase were the most adequate, requiring little work of tuning at the end and allowing the extraction of parts with high repeatability of features and fulfilling the quality required by the customer.
