Sticking / Soldering
Review local die temperature, spray coverage, alloy contact time, and film strength. Increasing spray quantity alone can create new problems.

Troubleshooting
Common Die Casting Defects
Start with the visible symptom, then review equipment and process conditions before changing the release agent.
Build-up / Dirty Die
Check overspray, cold die areas, incomplete evaporation, and residue from active materials. A lower-residue direction may be appropriate.
Gas Porosity
Confirm spray drying, venting, vacuum, plunger lubrication, and release-agent quantity. Product choice is only one part of the gas load.
Paintability / Bonding Issues
Review residue, silicone requirements, cleaning effectiveness, and the complete coating or bonding sequence using actual production parts.
Process Controls
Three variables to verify first.
Die Temperature Window
A die that is too cold can retain water and active material. A die that is too hot can prevent uniform deposition. Stable film formation depends on an effective temperature window.
Dilution Ratio
There is no universal setting. Determine dilution against the release agent, machine, casting geometry, spray system, water quality, and target surface condition.
Spray Quantity
More spray is not automatically better. Excess can increase cooling, residue, gas load, wastewater, and cycle time. Use the minimum quantity that maintains reliable release.
