Choose a die-casting release agent tailored to the application’s demands:
For processes requiring high temperature resistance, opt for agents with superior thermal stability and chemical inertness.
For applications with strict cleaning/coating requirements, select agents with excellent cleanability.
When testing, focus on the dilution ratio calibrated to the same solid content.
Do not use a spectrophotometer to compare different release agent types: manufacturers use unique raw material compositions and formula proportions, and even variants of the same product with different solid contents can behave significantly differently.
If the test sample’s solid content deviates drastically from the baseline, adjust the dilution ratio accordingly. Over-concentrated application may lead to a rough or uneven mold surface finish.
During testing:
Conduct evaluations when the die-casting machine is operating under normal production conditions.
Take periodic samples (at irregular intervals) and compare them to the original release agent to track performance consistency.
Include tests for downstream process impacts, such as:
Salt spray corrosion testing (to assess resistance to environmental degradation);
Electroplating/electrophoretic coating compatibility (to ensure the release agent does not interfere with adhesion or finish quality).
