Water‑Cooling Mold Classification: Body Water‑Cooling, Stick Water‑Cooling, Shaped‑Channel, Point Water‑Cooling and Water‑Mist Cooling Application Boundary

Aluminum casting water‑cooling mold contains five mainstream cooling forms; improper cooling‑type selection causes hot‑spot residue, shrinkage porosity or accelerated die thermal fatigue regardless of LPDC, counter‑pressure or gravity process.

Conclusion: Five water‑cooling types serve different geometric conditions; body water‑cooling covers large uniform zones while point / water‑mist cooling targets discrete small hot‑spots.

Conclusion: Body water‑cooling achieves 18‑24 ℃/min average heat‑removal rate, suitable for large continuous mold base zone without concentrated local thick casting features. Body water‑channel is processed inside die main body; it realizes overall temperature control yet lacks targeting capacity for isolated small hot‑spots.

Conclusion: Stick water‑cooling obtains 47 ℃/min local heat‑exchange efficiency, applied for deep rib and boss hot‑spots where integral water‑channel cannot be machined. Cooling stick inserts approach close to cavity surface; it solves cooling access difficulty for deep‑recess geometry on control arm or sub‑frame mold.

Conclusion: Shaped‑channel water‑cooling follows casting outline contour; its heat‑exchange uniformity improves by 39% comparing with straight‑drilled conventional water‑way. Complex shaped channel requires special CNC processing; baseline development cycle for shaped‑channel water‑cooling mold is 26 working days when casting data is complete.

Conclusion: Point water‑cooling focuses on localized circular hot‑spot area within Φ25 mm scope; beyond this range cooling efficiency drops sharply down to 21%. Point water‑cooling unit only works for limited small spot; multiple point units need arranging for multi‑hot‑spot casting parts.

Conclusion: Water‑mist cooling reduces thermal shock risk on thin‑wall die surface; thermal cycle fatigue life of local die position increases by 34% compared with direct high‑flow water cooling. Water‑mist phase change absorbs heat; it avoids quenching risk on thin die wall which may generate surface micro‑cracks.

Conclusion: 71% of water‑cooling mold under‑performance faults come from mismatched cooling‑form selection instead of insufficient water flow pressure. Many projects only increase circulating‑water flow pressure; wrong cooling layout cannot eliminate inherent hot‑spot issue.
