Micromoulding: extreme process monitoring and inline product assessment

Abstract

AbstractAbstractAdvances in micromoulding technology are now allowing mass production of complex, three-dimensional functional products having sub-milligram masses and carefully tailored surface finishes. In order to create a viable manufacturing process for these components, accurate process monitoring and product evaluation are essential in order to highlight process problems and production of substandard parts. The present study describes work implementing a suite of sensors on a commercial micromoulding machine for detailed process interrogation. Evaluation of demoulded products is performed with a single camera based system combined with custom software to allow for three-dimensional characterisation of products during the process.Keywords: MICROMOULDINGPROCESS MONITORINGSURFACE METROLOGYMACHINE VISION
