Plastic injection molding is one of the most used manufacturing technologies globally. Traditional cooling systems typically employ straight-drilled channels that are not optimized for complex part geometries, often resulting in prolonged cooling times, increased cycle durations, and potential product deformation. This study evaluates the effectiveness of conformal cooling channels as a solution to these limitations. Numerical simulations were performed using “SolidWorks Plastics”. A standard cooling configuration for a polymer whiteboard eraser was selected for case study geometry. Subsequently, a conformal cooling system, designed to follow the geometry of the part, was simulated under identical conditions. The results showed a reduction in both cooling and cycle times, highlighting the engineering and manufacturing advantages of conformal cooling in injection molding processes.
Keywords: conformal channels, conventional channels, cooling time, cycle time

This study presents the mechanical design of a “Sievert System” for hydrogen storage applications. In response to the growing demand for safe and efficient hydrogen handling technologies, the project focused on developing the system architecture, with particular emphasis on the adsorption vessel. The final design integrates control valves, a vacuum pump, a hydrogen storage tank, pressure sensors, and seals. ‘Finite element analysis’ (FEA) of mechanical stress was conducted on the adsorption vessel to ensure mechanical integrity under operational conditions. Several design iterations were required to address challenges related to sealing effectiveness and component integration. Based on this research, a system prototype will be developed and constructed for future experimental validation in hydrogen storage applications.
Keywords: adsorption vessel, finite element analysis, hydrogen, mechanical design, “Sievert System”
