Poiché i produttori di autoveicoli richiedono un sempre più elevato livello di qualità delle guarnizioni, è ormai indispensabile che i produttori di guarnizioni raggiungano cicli di produzione molto stabili caratterizzati da una minima quantità di difetti e scarti. Pertanto, per lo stampaggio a iniezione della gomma è divenuto necessario sviluppare un adeguato controllo di processo tale da tener conto delle sue fluttuazioni. Dal punto di vista della sostenibilità, gli scarti di gomma non si degradano e rimangono a lungo nell'ambiente. Pertanto, per aumentarne la sostenibilità, la prima strateg

<p>This thesis is devoted to analysis and optimization of the injection molding process with a focus on the mold. In the analysis, both process parameters and the design of the mold are taken in consideration. A procedure has been developed, i.e. a method and a program code, which enables optimization of different quantities, not only restricted to injection molding simulation, by altering different variables. There are many ways to interpret the word “optimization”. In this work, “optimization” means the use of mathematical algorithms in order to maximize or minimize any given quantity. This

Abstract:
Numerical simulation for injection molding has been developed and accepted by the processing industry to improve productivity, part quality and to shorten start-up times. In the particular case of micro injection molding, numerical simulation is all the more crucial since processors deal with much more basic problems than in the case of classical injection molding. Due to the small part dimensions prevailing in micro molding, it is not uncommon to be faced with the total incapacity to achieve complete filling of the micro cavity or to eject the solid part.

Abstract:
碩士<br>長庚大學<br>機械工程研究所<br>88<br>The effort of this thesis is to derive the optimal processing parameters of the Gas-Assisted Injection Molding process (GAIM) by the use of an artificial neural network (ANN). This approach is proposed because the effects of processing conditions, such as the applied pressure, plug material, its geometry and extruding velocity, and the local temperature, are highly nonlinear and fully coupled. The complexity of the process makes the operation design a difficult task, even with the existence of a reliable physical model. Usually, prolonged tests must be conducted.

On account of labor shortage in the recent years, companies have adopted a new business model where labors are replaced by machines, resulting in rapid product and service delivery. Hence, being able to improve productivity and product quality has become the new competitive advantage for companies. And what determines the competitive advantage is its Manufacturing Capability Optimization. However
