The objective of this paper is to present a methodology for optimal design of cooling systems
for multi-cavity injection mold tooling. After the part layout and the injection mold are
designed, the methodology optimizes cooling system layout in terms of cooling channel size,
locations, and coolant flow rate. The mold cooling design is modeled as a non-linear
constrained optimization problem. The objective function for the constrained optimization
problem is stated as minimization of both a function related to part average temperature and …
