Abstract

This report discussed about how to solve problem arise from casting process by using the TRIZ Methodology. TRIZ methodology is a theorem use for creating an ideal solution in solving a problem, it is done by solving the contradiction arise in the problem. During the project, casting process is selected as the case study for application of TRIZ methodology in order to solve the defects arise in the process; theory designed aims to solve the problem innovatively. Initial part of the report discussed about casting process and followed by the common type and cause of defects found in casting process. Further on, discussion in the report continue to discuss about the solution towards casting defects, it is done by using TRIZ methodology (Mini-ARIZ and 40 innovative principles). Principles selected will be applied in this report, it tends to show how to solve manufacturing problem in casting and come out with a concrete solution, which is cost effective and efficient from various aspect. As for result and outcome of experiment, TRIZ implementation brings a major impact towards the result of casting. During the case study, TRIZ application has successfully solved four main problems identified in the casting experiment; these defects include surface cavities defects (pinholes), flash formation, rough surface and metallic projection. TRIZ application has successfully solved the problem by generating useful guidance and provides direction in future steps. Report also include the result and verification of solution effectiveness, solution generated outcome has been verified and proven to be effective by experiment. As in general, TRIZ successfully solve the problem of flash formation, rough surface, metallic projection and reduce the formation of surface cavities.
