【Q&A】Why doesn't the maintenance frequency decrease in high-temperature environments? 【Part 3】
In high-temperature environments such as die-casting molds, we sometimes receive inquiries stating that even when using high-temperature grease, the maintenance frequency does not decrease as expected.
What are the reasons behind the notion that "heat-resistant grease = reduced maintenance frequency" not necessarily being true?
In high-temperature environments, several complex factors come into play, including:
- Evaporation and separation of oil
- Oil film breakdown due to load and repeated sliding
- Contamination by fine wear particles
- Changes in properties due to temperature fluctuations
As a result, simply having a high heat resistance does not guarantee the maintenance of a stable lubrication state.
In this third installment, we will clarify:
✔ Why degradation progresses more easily in high-temperature environments
✔ The mechanisms behind seizure and sticking
✔ How to approach the decision for reapplication
If you want to reassess the maintenance of high-temperature molds, please take a look.
