【 摘 要 】

This research was about the development of mould for rheology test sample via simulation. The development work concerned with stages of design, simulation, analysis, and fabrication of the mould to produce good quality samples. In the design stage, three mould concepts have been prepared via Solid Works software. The simulation of injection moulding was conducted by using CadMould 3D-F software. Then, in the analysis stage, the main factor that has been studied were the cavity system, runner system and the gating system. For each design, different type of systems were applied to compare different simulation result. Through the simulation software, it was rectified that the parameter such as the number of cavities, filling time, shear stress were the main factors to contribute good rheological properties of the sample. The final result shows that Design 2 was chosen as the suitable mould due to number of cavities and good results in the analysis, as compare to other mould design. Finally, Design 2 have been fabricated and undergo fitting test to see whether the dimension had been done correctly. Based on this research findings, it was proven that to develop a mould suitable for rheology sample, the mould design selection should be made based on the type of system in simulations.
