Automated Design of Honeycomb Conformal Cooling Channels for Improving Injection Molding Quality

Production Engineering Archives, 2023
The study of conformal cooling channel usually has adopted two assumptions in model design: the use of (1) a hot runner system and (2) a one-mold-one-cavity design. These assumptions substantially simplify the research.
