A mold assembly for an injection molding machine, the mold assembly comprising:
- a first mold side and a second mold side, the first mold side and the second mold side defining a mold cavity therebetween;
- a first mold support plate being disposed one of immediately adjacent to or in direct contact with the first mold side;
- a second mold support plate being disposed one of immediately adjacent to or in direct contact with the second mold side;
- and
- an evaporative cooling system for removing heat from one of the first and second mold sides during an injection molding process, the evaporative cooling system including one or more cooling fluid channels,
- wherein none of the cooling fluid channels of the evaporative cooling system extends into the first mold side or the second mold side.
