The advancement of manufacturing technology has resulted in an increasing need for detailed, lightweight, and high-performance components with complicated geometries across many sectors. The emergence of advanced casting processes has been crucial in addressing these needs, as they provide the potential to manufacture components with complex geometries, enhanced mechanical characteristics, and minimised material wastage. The present study delves into the intricate domain of advanced casting processes, with a specific emphasis on the areas of design, simulation, and process control. The design of components with intricate shapes poses difficulties that conventional casting techniques encounter difficulties in surmounting. Simulation methods are crucial for accurately predicting the solidification and flow characteristics in casting processes, as this is essential for the production of components without any defects. Sophisticated simulation technologies, like as computational fluid dynamics (CFD) and finite element analysis (FEA), are utilised in advanced casting processes to model and analyse the intricate thermal and fluid dynamics phenomena that transpire during the casting process. This research provides an in-depth analysis of the role of simulations in enhancing the comprehension of solidification patterns, the identification of probable faults, and the optimisation of gating and riser designs to improve the overall quality of castings.

“…This shortens the cooling time and thus enables taking out the shapes from the mold fast. [30][31][32][33] After heating the molded powder-plastic composites at elevated temperature, the polymer network decomposes and the powders of metals, ceramics, or alloys densify into complex shapes with a high precision.…”

A conformal cooling channel (CCC) follows the mold core or cavity profile to carry out uniform cooling in the cooling stage. However, the significant pressure drop along the cooling channels is a distinct disadvantage of the CCC. In this study, an innovative waterfall cooling channel (WCC) was proposed and implemented. The WCC cools the injected products via surface contact, replacing the conventional line contact to cool the injected products. The WCC was optimized using numerical simulation software. Silicone rubber molds with two kinds of cooling channels were designed and implemented. The cooling time of the molded part was evaluated using a low-pressure wax injection molding machine. The experimental results of the cooling time of the molded part were compared with the simulation results from numerical simulation software. The results showed that the optimal mesh element count was about 1,550,000 with a mesh size of 1 mm. The simulation software predicted the filling time of the water cup injection-molded product to be approximately 2.008 s. The cooling efficiency for a silicone rubber mold with a WCC is better than that of the silicone rubber mold with a CCC since the core and cavity cooling efficiency is close to 50%. The pressure drop of the WCC is smaller than that of the CCC, which reduces the pressure drop by about 56%. Taking a water cup with a mouth diameter of 70 mm, a height of 60 mm, and a thickness of 2 mm as an example, the experimental results confirmed that the use of the WCC can save the cooling time of the product by about 265 s compared with the CCC. This shows how a WCC can increase cooling efficiency by approximately 17.47%.
