To tackle die sticking using die-casting release agents, follow these steps:
Analyze sticking location and root cause: First, identify where die sticking occurs and its characteristics (e.g., whether it is in high-temperature areas). Pinpoint the reason: insufficient heat resistance of the release agent due to excessively high temperatures; inadequate cooling from overly concentrated release agent causing local sticking; or complete lack of spray coverage in certain spots.
Optimize spraying process: Prioritize uniform spray coverage of the mold surface. For hot spots, adjust spraying parameters (time, pressure, angle, distance, atomization effect) and dilution ratio to reduce mold temperature and ensure complete part forming.
Upgrade release agent: If sticking persists after the above adjustments, switch to a release agent with higher heat resistance. Note: Do not arbitrarily use a more concentrated release agent upon encountering die sticking. Only if spraying is optimal (with uniform coverage) but sticking still occurs, can the release agent concentration be moderately increased.
Important: This guide focuses solely on release agent-related solutions. In practice, comprehensive judgment must integrate die-casting parameters like temperature, speed, time, and pressure.
