Saikumar Amda, Dr. N.V. Srinivasulu, Dr. L.Sivarama Krishna 02 07 The design and analysis of multicavity cap moulds using ANSYS Fluent for the simulation of the injection molding process The study investigates three distinct multicavity cap designs 2cavity threaded 8cavity threaded and 8cavity fliptop moulds commonly used in manufacturing caps for packaging pharmaceuticals and consumer goods The primary aim is to optimize the molding process by evaluating key parameters such as melt flow temperature distribution cooling efficiency and pressure drop during both the injection and cooling phases Using SolidWorks 3D models of the cap moulds are created and analyzed through CFD simulations in ANSYS Fluent to study the fluid dynamics heat transfer and material behavior within the mould The simulations help in understanding fill patterns melt front progression and the impact of cooling channel layouts on temperature uniformity across the cavities The performance of each mould configuration is evaluated in terms of cycle time energy consumption and potential defect formation such as warping short shots and air traps offering insights into optimizing the mould design for improved efficiency and part quality The findings highlight the importance of integrated CFD analysis in multicavity mold design emphasizing the role of cooling system optimization to reduce defects and improve overall efficiency in industrial manufacturing processes Copyright (c) Journal of Science Engineering Technology and Management Science.
