GETTING HEAT OUT OF THE MOLD WHERE WATER WON'T GO

摘要

Removing heat from complex areas of an injection mold is difficult and often remains unresolved in production tooling. Cycle times and/or dimensional stability are often sacrificed because of hot spots in the tool. This study investigated a variety of strategies employing copper alloys with and without water to the mold core. This study provided several surprises to the research team and identified one practical method for removing heat from non-watered cores. Application of high thermal conductivity copper alloys to the correct combination of components should allow mold engineers to solve both current and future mold cooling problems.
