It has a significant impact. High-quality release agents form a protective film on the mold surface, reducing erosion and wear from high-temperature, high-pressure molten metal, mitigating thermal fatigue, and thereby extending mold life. Conversely, inferior release agents may fail to protect effectively—even corroding the mold—and shorten its service life. For instance, in high-mold-temperature scenarios, thermally stable die casting release agents must be selected to withstand intense molten aluminum erosion and meet the mold’s high-temperature resistance requirements.
