Traditional drilled cooling lines are limited to straight paths, often leaving “hot spots” that cause uneven cooling, longer cycle times, and part warpage. Metal Additive Manufacturing (AM) is fundamentally changing this by enabling the production of conformal cooling channels.
These channels are optimally designed to follow the precise contours of the mold cavity and core. This results in:
✅ Highly uniform heat transfer, drastically reducing cooling time.
✅ Minimized thermal stresses & warping, ensuring superior part quality.
✅ Increased productivity through faster cycle times.
✅ Extended mold life by eliminating thermal fatigue from hotspots.
The impact is most profound for high-performance plastic injection molds with complex geometries, where traditional cooling is least effective. AM allows for topological optimization, merging cooling efficiency with structural integrity.
This is not just an incremental improvement; it’s a paradigm shift in injection mould tooling design for optimal thermal management. It bridges the gap between ideal design and manufacturable reality.
