Proper use of release agents is a systematic process involving selection, preparation, spraying, and mold maintenance.
Choose release agents based on casting requirements. For example:
For castings requiring high-performance post-coating (e.g., painting), prioritize silicon-free release agents to prevent silicone oil migration from compromising coating adhesion.
Select release agents tailored to mold operating temperatures: low-temperature (below 200°C), medium-temperature (200–250°C), or high-temperature (above 250°C) formulations.
The quality of dilution water is critical. Impure water containing contaminants, minerals, or microorganisms can disrupt release agent stability, cause degradation, and increase risks of casting porosity or filter clogging.
Use purified or deionized water where possible, following technical data sheet (TDS) guidelines for dilution ratios.
If purified water is unavailable, tap water is acceptable; avoid well water, groundwater, or recycled water.
Atomization Quality: Ensure the spray gun produces fine, uniform atomization for consistent film formation.
Spray Distance and Angle: Maintain a typical spray distance of 80–200mm. Use multi-angle cross-spraying to ensure full coverage of all cavity surfaces.
Mold Temperature Coordination: Spray when mold temperature is within 200°C–280°C for optimal results. Avoid excessive spraying at low mold temperatures.
After each spray, use compressed air to "blow off debris," removing excess release agent and potential residues.
Regularly protect molds to prevent carbon buildup and dirt accumulation.
