The dilution ratio of die-casting release agents is generally determined by customer operating conditions, including die-casting machine tonnage, mold temperature, spray time/volume, casting complexity, spraying equipment, and post-processing cleaning/coating requirements. For example:
When using large-tonnage die-casting machines, high mold temperatures, long spray durations, large spray volumes, or complex castings, the dilution ratio is typically lower (to ensure sufficient film formation and protection).
Conversely, simpler conditions allow for a higher dilution ratio.
Notably, the normal dilution ratio for magnesium alloy die casting is lower than that for aluminum alloy. Under standard circumstances, a 20% concentration release agent for 1000–2000 ton die-casting machines requires a dilution ratio of approximately 100–150 times.
