Injection Mold cooling

As you consider and develop the heat transfer methodology in a new injection mold, You cannot lose sight of the cooling media flow rate. The larger the flow channel, the higher the flow rate must be to generate and maintain turbulent flow within the injection mold cooling channel, which is a prerequisite to efficient heat transfer out of the insert. By the same token, more parallel channels will require higher flow rates. Most injection mold designers do not have detailed information from the processor at this level, and this detail is generally overlooked.
When considering conformal cooling as was indicated in the curved axis drilling discussions, There is a point where you Must consider control of the thermal mass and this becomes an area of compromise based on the economics involved.
Conformal injection mold cooling works! But, It is not always feasible.
