Colder or faster mold water
Clean the water channels of a mold and raise the flow, or run the water colder, where the job allows it.
| Cost | About $420 per mold in toolroom time |
| Payback | Not counted |
| Limitation | We did not see how much water flows through any mold, so what it would add is not known. Colder water can change how a part looks and shrinks. |
