The automotive industry's demand for efficient production has led to innovations in mold design. Research by Çalışkan et al. (2021) demonstrated that utilizing additive manufacturing to create conformal cooling channels (CCCs) in injection mold cores can reduce cycle times by up to 38%. This is achieved by enabling cooling channels that precisely follow the contours of the part being molded, ensuring more uniform and effective heat dissipation compared to traditional straight channels, which are limited by CNC machining capabilities. This highlights the potential of advanced manufacturing to significantly improve production efficiency and address thermal management challenges in complex manufacturing processes.
