Mold Cooling Channel Design

Design Principles

• Distance from cavity: 2-2.5x channel diameter
• Channel spacing: 3-5x diameter
• Channel diameter: 8-16 mm
• Turbulent flow required (Reynolds > 4000)

Cooling Enhancement

• Baffles for deep core cooling
• Bubblers for fountain cooling
• Thermal pins for hot spots
• Conformal cooling for best uniformity
