Optimizing cooling for shorter cycle time and less warpage
| Type | Cooling Efficiency | Manufacturing Cost | Cleanability |
|---|---|---|---|
| Straight Drilling | Fair | Low | Easy |
| Bubbler | Good | Medium | Moderate |
| Baffle | Good | Medium | Moderate |
| Conformal (3D Printed) | Excellent | High | Difficult |
| Thermal Pin (Heat Pipe) | Excellent | High | N/A |
Rule: cooling distance = 2-2.5x channel diameter. Channel diameter should be 8-12mm for most molds. Water velocity > 1.5 m/s for turbulent flow.
