Pattern design for investment casting / Mohammad Naimie Mohamed Bakari and Rosniza Rabilah

Investment casting is an advanced Metal Forming process used to produce metal parts of the highest quality, functionality and cost-effectiveness. Investment casting is a one-to- one process in which one disposable pattern produces one metal part. When combined with modem production knowledge and technologies, investment casting can be applied to produce parts of varying degrees of complexity, in virtually any volume and for the broadest possible spectrum of applications.
Our project paper is based on new pattern design, which focused for the pattern and new style for UiTM Pulau Pinang. The main purpose of this project is to minimize the cost making the die and produce flexibly for any type of patterns.
We also want to study about investment casting process. We designed a simple FKM Souvenir for Faculty of Mechanical Engineering. The souvenir that we had design is a prototype with 1:1 scale. The patterns are designed for to add the pattern that available at UiTM Penang foundry workshop. In this project we use a polystyrene to make the pattern. We don’t use the wax to make the pattern because we don’t have a complete equipment to make their mold. Furthermore the cost to build the mold is very expensive. The material use for this souvenir is 100% pure Aluminium. We have given all of our best performance to achieve the fully satisfaction in this project. However the patterns that we designed are still not a perfect creation and still need much of modification. So, we hope that this project will be a great and useful in the future with suitable correction and improvement.
