| Summary: | This research is about generating models of injection moulding processing conditions,
towards quality performance of polypropylene-nanoclay integral hinges, exposed to
high heat temperature. The assessment of hinges’ quality performance analyses was
translated as the signal to noise ratio values for ultimate tensile strength, shrinkage and
warpage. This research had adopted Taguchi Optimisation Method, to optimise the
processing conditions, to generate the regression models and to construct master
curves for quality performance prediction based on nanoclay content. According to the
results, 18 regression models have been successfully generated. 3 types of master
curves have been constructed based on the produced models with the specific nanoclay
content. Additionally, the quality performance of the integral hinges was extended to
high heat exposures, and the additional of nanoclay had produced a significant
advancement in the injected mould samples. Validation test has been carried out
towards the regression model with most of the models have produced good predictions
of quality performances. The novelty of this research is the correlations between the
optimum injection moulding processing conditions with the precise range of
shrinkage, warpage and ultimate tensile strength. The correlations were simplified in
the form of regression models and master curves. These models and master curves
were recommended as references and a prediction method, specifically for
polypropylene-nanoclay integral hinges manufacturing and design process. These
findings will lead to wider and optimum applications of thin layer parts and
components such as packaging products; as well as other manufacturing field such as
artificial human parts development and building appliances. |
