A recent product development from HASCO, the Z99 CoolCross is making routing of cooling channels easier and more efficient.

With this new system, it is possible to have cooling channels crossing each other on the same plane in a flexible and inexpensive manner.
The CoolCross injection mold cooling system permits a homogeneous temperature distribution, as well as constant cavity cooling on all four sides for the full duration of the injection molding cycle.
We think this is a good step forward and recommend that you try it in your next tool build.
