Effect of oxo treatment on aluminum die cast mold and peripheral parts

・　Reduction of peeling (double flow is suppressed by improving hot water flow)
・　Reduces the occurrence of nests and sink marks (reduces the amount of coagulated pieces and improves hot water circulation)
・　Suppresses seizure and galling (unevenness improves cooling effect and forms chill layer)
・　Delayed occurrence of heat check (heat fatigue countermeasures are possible by increasing residual compressive stress and hardness)
・　Countermeasures against stress corrosion cracking (strengthening the durability of the cooling circuit and extending the life of the mold)
・　Prevents aluminum from adhering to the hot water level detection rod and makes it maintenance-free.
