Conformal Tool Cooling

Thermal Management

Conventional cooling lines are restricted to straight drilled paths that often leave thick areas of the part with inadequate cooling. Conformal tool cooling maintains a constant distance from the cavity surface, preventing localized hot spots that lead to differential shrinkage and part warping. This thermal control reduces internal stresses and improves dimensional stability in the finished component.

Modern additive manufacturing processes allow the fabrication of these complex internal channels.

Cycle Optimization

Moulding cycle times are dominated by the time required for the polymer to solidify sufficiently for ejection. Optimizing conformal tool cooling allows rapid heat extraction, which significantly reduces the cooling phase of the cycle. A shorter cycle increases overall equipment effectiveness and lowers the per-part production cost in high-volume runs.

The faster cooling rate also influences the crystalline structure of semi-crystalline polymers, sometimes enhancing mechanical properties.

Channel Configuration

Fluid dynamics within the cooling circuit must be carefully balanced to prevent stagnant flow and maintain turbulent flow conditions. The design of conformal tool cooling paths must account for pressure drops and flow rates to ensure efficient thermal transfer. Using multi-channel manifolds allows even distribution of the cooling fluid throughout the mould.

A well-designed cooling circuit prevents premature tool wear and reduces maintenance intervals.
