Abstracts: Injection Moulding (IM) is considered to be one of the most prominent processes for mass production of plastic products. One of the biggest challenges, facing injection molders today, is to determine the proper settings for the IM process variables. Selecting the proper settings for an IM process is crucial because the behavior of the polymeric material during shaping is highly influenced by the process variables. Consequently, the process variables govern the quality of the parts produced. The difficulty of optimizing an IM process is that the performance measures usually show conflicting behavior. Therefore, a compromise must be found between all of the performance measures of interest. After the implementation of the proposed method, targets for improvement are clearly defined with the problems and causes being identified. This work also presents a novel, general and intelligent approach to multi response process optimization, with a purpose to obtain a single optimum setting of process parameters that meets specifications of all considered, possibly correlated, responses.
